RISK FACTORS

Any investment in our common stock involves a high degree of risk. You should consider carefully the risks and uncertainties described below and all information contained in this prospectus, before you decide whether to purchase our common stock. If any of the following risks or uncertainties actually occurs, our business, financial condition, results of operations and prospects would likely suffer, possibly materially. In addition, the trading price of our common stock could decline due to any of these risks or uncertainties, and you may lose part or all of your investment.

Risks Related to Our Business

We have incurred significant losses since our inception and anticipate that we may continue to incur significant losses. If we fail to generate significant revenue from sales of our marketed products, we may never achieve or sustain profitability.

As of March 31, 2010, we had an accumulated deficit of approximately $44,539,000. The accumulated deficit has resulted principally from costs incurred in our research and development efforts and general operating expenses. We have incurred significant losses in each year since our inception in 1998. Net losses were approximately $2,516,000 for the three months ended March 31, 2010, approximately $7,159,000 for the year ended December 31, 2009, approximately $5,430,000 for the year ended December 31, 2008, and approximately $3,697,000 for the year ended December 31, 2007. We may continue to incur significant operating losses as we continue to invest capital in the sales and marketing of our marketed products, development of our product candidates and our business generally. We also expect that our general and administrative expenses will increase due to additional operational and regulatory burdens associated with operating as a public company.

As a result of the numerous risks and uncertainties associated with developing medical devices, we are unable to predict the extent of any future losses or when we will become profitable, if at all. Our profitability will depend on revenues from the sale of our marketed products. While we recently began marketing of our ClearPoint system in the United States by directly contacting key physicians and hospitals, we may never achieve significant revenues. Therefore, we cannot provide any assurance that we will ever achieve profitability and, even if we achieve profitability, that we will be able to sustain or increase profitability on a quarterly or annual basis. Further, because of our limited commercialization history, we have limited insight into the trends that may emerge and affect our business. We may make errors in predicting and reacting to relevant business trends, which could harm our business and financial condition. Any failure to achieve and maintain profitability would continue to have an adverse effect on our stockholders’ equity and working capital and could result in a decline in our stock price or cause us to cease operations.

Although we have obtained regulatory clearance to market our ClearPoint system in the United States, it may not achieve market acceptance or be commercially successful.

We expect sales of our ClearPoint system will account for the vast majority of our revenues for at least the next several years. Although we received regulatory clearance for our ClearPoint system and we have begun marketing in the United States by directly contacting key physicians and hospitals, our marketed products may not gain market acceptance unless we convince physicians, hospitals and patients of the benefits of our marketed products. Moreover, even if physicians and hospitals understand the benefits of our marketed products, they still may elect not to use our ClearPoint system for a variety of reasons, including:

7

Table of Contents

Index to Financial Statements

We believe that the market for our ClearPoint system is fairly concentrated among a few hundred hospitals. If physicians and hospitals do not perceive our ClearPoint system as an attractive alternative to other products and procedures, we will not achieve significant market penetration or be able to generate significant revenues, if any. To the extent that our ClearPoint system is not commercially successful or is withdrawn from the market for any reason, our revenues will be adversely impacted and our business, operating results and financial condition will be harmed.

If we fail to obtain regulatory approval for our ClearPoint system in foreign jurisdictions, we will not be able to expand the commercialization of our marketed products abroad.

Currently, we market our ClearPoint system in the United States; however, we also intend to sell our ClearPoint system in the European Union. To market a product in the European Union, we must be entitled to affix a CE mark, an international symbol of adherence to quality assurance standards and compliance with applicable European Union medical device directives. A CE mark would enable us to market a product in all of the countries of the European Union, as well as in other countries, such as Switzerland and Israel, that have mutual recognition agreements with the European Union or have adopted the European Union’s regulatory standards. There can be no assurance that we will receive CE marking approval for our ClearPoint system. To sell our ClearPoint system in other foreign jurisdictions, we will have to obtain separate regulatory approvals from those foreign jurisdictions as well. The regulatory approval process varies among jurisdictions and can involve substantial additional testing. Clearance or approval by the FDA does not ensure clearance or approval by regulatory authorities in other jurisdictions, and clearance or approval by one foreign regulatory authority does not ensure clearance or approval by regulatory authorities in other foreign jurisdictions. The foreign regulatory approval process may include all of the risks associated with obtaining FDA clearance or approval in addition to other risks. In addition, the time required to obtain foreign clearance or approval may differ from that required to obtain FDA clearance or approval and we may not obtain foreign regulatory clearances or approvals on a timely basis, if at all. We may not be able to file for regulatory clearance or approval and may not receive necessary clearance or approval to commercialize our ClearPoint system in any foreign market, either of which would preclude sale of our ClearPoint system in foreign jurisdictions.

We intend to apply for CE marking approval for sale of our ClearPoint system during 2010, and we have engaged KEMA as the Notified Body for our CE marking approval process. A Notified Body is a private commercial entity that is designated by the national government of a European Union member state as being competent to make independent judgments about whether a device complies with applicable regulatory requirements. The exact regulatory pathway for CE marking approval for our ClearPoint system will be the subject of discussions that we have with KEMA. At this time, we are unable to accurately predict when, if ever, CE marking for our ClearPoint system will be obtained, whether clinical trials will be required as part of the CE marking approval process or the regulatory requirements to which we would be subject after approval.

If hospitals and physicians are unable to obtain adequate coverage and reimbursement from third-party payors for procedures utilizing our ClearPoint system, our revenues and prospects for profitability will suffer.

We anticipate that our ClearPoint system components will be purchased primarily by hospitals, which bill various third-party payors, including governmental healthcare programs, such as Medicare, and private insurance plans, for procedures in which our marketed products will be used. Reimbursement is a significant factor considered by hospitals in determining whether to acquire new medical devices such as our marketed products. Therefore, our ability to successfully commercialize our ClearPoint system depends significantly on the availability of coverage and reimbursement from these third-party payors.

Medicare pays hospitals a prospectively determined amount for inpatient operating costs. The prospective payment for a patient’s stay is determined by the patient’s condition and other patient data and procedures

8

Table of Contents

Index to Financial Statements

performed during the inpatient stay using a classification system known as Medical Severity Diagnosis Related Groups, or MS-DRGs. Medicare pays a fixed amount to the hospital based on the MS-DRG into which the patient’s stay is assigned, regardless of the actual cost to the hospital of furnishing the procedures, items and services provided. Therefore, a hospital must absorb the cost of our marketed products as part of the payment it receives for the procedure in which the product is used. In addition, physicians that perform procedures in hospitals are paid a set amount by Medicare for performing such services under the Medicare physician fee schedule. Medicare payment rates for both systems are established annually.

At this time, we do not know if hospitals will consider third-party reimbursement levels adequate to cover the cost of our marketed products. Furthermore, we do not know if physicians will consider third-party reimbursement levels adequate to compensate them for performing the procedures in which our marketed products are used. Failure by hospitals and physicians to receive an amount that they consider to be adequate reimbursement for procedures in which our marketed products are used will deter them from purchasing or using our marketed products and limit our sales growth.

One result of the current Medicare payment system, which is also utilized by most non-governmental third-party payors, is that a patient’s treating physician orders a particular service and the hospital (or other facility in which the procedure is performed) bears the cost of delivery of the service. Hospitals have limited ability to align their financial interests with those of the treating physician because Medicare law generally prohibits hospitals from paying physicians to assist in controlling the costs of hospital services, including paying physicians to limit or reduce services to Medicare beneficiaries even if such services are medically unnecessary. As a result, hospitals have traditionally stocked supplies and products requested by physicians and have had limited ability to restrict physician choice of products and services.

The Patient Protection and Affordable Care Act enacted on March 23, 2010, as amended by the Health Care and Education Reconciliation Act of 2010 enacted on March 30, 2010, or, together, the Health Care Reform Law, includes a number of provisions that will likely result in more coordination between hospitals and physicians resulting in the alignment of financial incentives between hospitals and physicians to control hospital costs. Most significantly, the Health Care Reform Law provides for the establishment of a Medicare shared savings program whereby Medicare will share certain savings realized in the delivery of services to Medicare beneficiaries with accountable care organizations, which may be organized through various different legal structures between hospitals and physicians. We expect that the overall result of such increased coordination will be voluntary reductions in the array of choices currently available to physicians with respect to diagnostic services, medical supplies and equipment. Such a reduction in physician choices may also result in hospitals reducing the overall number of vendors from which they purchase supplies, equipment and products. The Health Care Reform Law may make it more difficult for us to become and remain an approved vendor, which could have an adverse effect on our financial results and business.

If there are changes in coverage or reimbursement from third-party payors, our revenues and prospects for profitability will suffer.

In the United States, we believe that existing billing codes apply to procedures using our ClearPoint system. Reimbursement levels for procedures using our ClearPoint system or any product that we may market in the future could be decreased or eliminated as a result of future legislation, regulation or reimbursement policies of third-party payors. Any such decrease or elimination would adversely affect the demand for our ClearPoint system or any product that we may market in the future and our ability to sell our products on a profitable basis. For example, on July 30, 2008, Centers for Medicare and Medicaid Services, or CMS, the federal agency that administers the Medicare Program, released a list of potential topics for national coverage determinations. This list included ablation for atrial fibrillation and specifically asked whether the evidence was adequate to demonstrate health benefits in patients who receive the procedure. On October 21, 2009, the Medicare Evidence Development and Coverage Advisory Committee held a meeting on the adequacy of the available evidence for catheter ablation for the treatment of atrial fibrillation. Although CMS has not formally opened a national coverage analysis on this topic, the agency has shown that it is interested in the clinical evidence of atrial

9

fibrillation treatments and any national coverage decisions it makes could have a material effect on the ClearTrace system and our potential business in this area. Furthermore, if procedures using our ClearPoint system gain market acceptance and the number of these procedures increases, CMS, as well as other public or private payors, may establish new billing codes for those procedures that provide for a lower reimbursement amount than traditional approaches, which would adversely affect our financial results and business.

Among other things, the Health Care Reform Law will ultimately increase the overall pool of persons with access to health insurance in the United States. Although such an increase in covered lives should ultimately benefit hospitals, the Health Care Reform Law also includes a number of cuts in Medicare reimbursement to hospitals that may take effect prior to the time hospitals’ realize the financial benefit of a larger pool of insured persons. Such cuts in Medicare reimbursement could adversely impact the operations and finances of hospitals, reducing their ability to purchase medical devices such as our ClearPoint system. Further, the fact that the Health Care Reform Law did not address pending reductions of Medicare physician payment rates under the sustainable growth rate formula could result in an overall reduction of physicians willing to participate in Medicare. Either of these events could adversely affect demand for our ClearPoint system, our business and our financial results.

If third-party payors deny coverage or reimbursement for procedures using our ClearPoint system, our revenues and prospects for profitability will suffer.

Notwithstanding its regulatory clearance in the United States, third-party payors may deny coverage or reimbursement if the payor determines that the use of our ClearPoint system is unnecessary, inappropriate, experimental, not cost-effective, or is used for a non-approved indication. In addition, no uniform policy of coverage and reimbursement for medical technology exists among third-party payors. Therefore, coverage and reimbursement for medical technology can differ significantly from payor to payor. Any denial of coverage or reimbursement for procedures using our ClearPoint system could have an adverse effect on our business, financial results and prospects for profitability.

If we are unable to expand our sales, marketing and distribution capabilities or enter into agreements with third parties to market, sell or distribute our ClearPoint system, we may be unable to generate material product revenues.

We have limited experience in the sales and marketing of medical devices. Currently, our sales and marketing efforts for our ClearPoint system are being coordinated primarily by our Vice President, Sales, our Vice President, Product Management and our two Clinical Engineering Managers. In order to successfully commercialize our ClearPoint system, we will need to expand our present sales and marketing capabilities, which could prove to be time-consuming and expensive. If we are unable to expand these capabilities, we will need to contract with third parties to help us market and sell our ClearPoint system. Likewise, if our current distribution capabilities are unable to satisfy customer demand for our ClearPoint system, we will need to contract with third parties to help us perform that function. To the extent that we enter into arrangements with third parties to perform sales and marketing or distribution services, our product revenues are likely to be lower than if we market, sell and distribute our ClearPoint system ourselves.

Our reliance on single-source suppliers could harm our ability to meet demand for our ClearPoint system in a timely manner or within budget.

Many of the components and component assemblies of our ClearPoint system are currently provided to us by single-source suppliers. We generally purchase components and component assemblies through purchase orders rather than long-term supply agreements and generally do not maintain large volumes of inventory. While alternative suppliers exist and have been identified, the disruption or termination of the supply of components and component assemblies could cause a significant increase in the cost of these components, which could affect our operating results. Our dependence on a limited number of third-party suppliers and the challenges we may face in obtaining adequate supplies involve several risks, including limited control over pricing, availability, quality and delivery schedules. A disruption or termination in the supply of components could also result in our inability to meet demand for our ClearPoint system, which could harm our ability to generate revenues, lead to

10

customer dissatisfaction and damage our reputation. Furthermore, if we are required to change the supplier of a key component or component assembly of our ClearPoint system, we may be required to verify that the new supplier maintains facilities and procedures that comply with quality standards and with all applicable regulations and guidelines. The delays associated with the verification of a new supplier could delay our ability to manufacture our ClearPoint system in a timely manner or within budget.

The Health Care Reform Law and other payment and policy changes may have a material adverse effect on us.

In addition to the reimbursement changes discussed above, the Health Care Reform Law will also impose a 2.3% excise tax on the sale of any taxable human medical device after December 31, 2012, subject to certain exclusions, by the manufacturer, producer or importer of such devices. Further, the Health Care Reform Law encourages hospitals and physicians to work collaboratively through shared savings programs, such as accountable care organizations, which may ultimately result in the reduction of medical device acquisitions and the consolidation of medical device suppliers used by hospitals. While passage of the Health Care Reform Law may ultimately expand the pool of potential end-users of our ClearPoint system, the above-discussed changes could adversely affect our financial results and business.

Further, with the increase in demand for healthcare services, we expect both a strain on the capacity of the healthcare system and more proposals by legislators, regulators and third-party payors to keep healthcare costs down. Certain proposals, if passed, could impose limitations on the prices we will be able to charge for our ClearPoint system, or the amounts of reimbursement available from governmental agencies or third-party payors. These limitations could have a material adverse effect on our financial position and results of operations.

Various healthcare reform proposals have also emerged at the state level. We cannot predict what healthcare initiatives, if any, will be implemented at the federal or state level, or the effect any future legislation or regulation will have on us. However, an expansion in government’s role in the United States healthcare industry may lower reimbursements for our ClearPoint system, reduce medical procedure volumes and adversely affect our business, possibly materially.

Our future success depends on our ability to obtain regulatory clearances or approvals for our current product candidates. We cannot be certain that we will be able to do so in a timely fashion, or at all.

We do not have the necessary regulatory clearances or approvals to market the ClearTrace system in the United States or in any foreign market. In the United States, without FDA clearances or approvals, we cannot market a new medical device, or a new use of, or claim for, or significant modification to, an existing product, unless an exemption applies. To obtain FDA clearance or approval, we must first receive either premarket clearance under Section 510(k) of the federal Food, Drug, and Cosmetic Act or approval of a premarket approval application, or PMA, from the FDA.

In the 510(k) clearance process, the FDA must determine that a proposed device is “substantially equivalent” to a device legally on the market, known as a “predicate” device, with respect to intended use, technology, safety and effectiveness, in order to clear the proposed device for marketing. Clinical data is sometimes required to support substantial equivalence. The 510(k) clearance process generally takes three to twelve months from submission, but can take significantly longer.

The process of obtaining PMA approval is much more costly and uncertain than the 510(k) clearance process. The PMA approval process can be lengthy and expensive and requires an applicant to demonstrate the safety and effectiveness of the device based, in part, on data obtained in clinical trials. The PMA process generally takes one to three years, or even longer, from the time the PMA application is submitted to the FDA until an approval is obtained.

Outside the United States, the regulatory approval process varies among jurisdictions and can involve substantial additional testing. Clearance or approval by the FDA does not ensure clearance or approval by regulatory authorities in other jurisdictions, and clearance or approval by one foreign regulatory authority does not ensure clearance or approval by regulatory authorities in other foreign jurisdictions. The foreign regulatory approval process may include all of the risks associated with obtaining FDA clearance or approval in addition to other risks. In addition, the time required to obtain foreign clearance or approval may differ from that required to obtain FDA clearance or approval and we may not obtain foreign regulatory clearances or approvals on a timely basis, if at all. We may not be able to file for regulatory clearance or approval and may not receive necessary clearance or approval to commercialize our product candidates in any foreign market, either of which would preclude sale of our product candidates in foreign jurisdictions.

To market a product in the European Union, we must be entitled to affix a CE mark, an international symbol of adherence to quality assurance standards and compliance with applicable European medical device directives. CE marking approval would enable us to market a product in all of the countries of the European Union, as well as in other countries, such as Switzerland and Israel, that have mutual recognition agreements with the European Union or have adopted the European Union’s regulatory standards.

The regulatory status of our current product candidates is as follows:

The FDA or any applicable foreign authority may not act favorably or quickly in its review of any regulatory submission that we may file or that Boston Scientific may file in connection with the SafeLead Development Program. Additionally, we or Boston Scientific may encounter significant difficulties and costs in obtaining clearances or approvals. If we or Boston Scientific, as the case may be, are unable to obtain regulatory clearances or approvals for our product candidates, or otherwise experience delays in obtaining regulatory clearances or approvals, the commercialization of our product candidates will be delayed or prevented, which will adversely affect our ability to generate revenues. Such delay may also result in the loss of potential competitive advantages that might otherwise be attained by bringing products to market earlier than competitors. Any of these contingencies could adversely affect our business. Even if cleared or approved, our product candidates may not be cleared or approved for the indications that are necessary or desirable for successful commercialization.

To the extent we seek a new indication for use of, or new claims for, our ClearPoint system, the FDA may not grant 510(k) clearance or PMA approval of such new use or claims, which may affect our ability to grow our business.

We received 510(k) clearance to market our ClearPoint system for use in general neurological interventional procedures. In the future, we may seek to obtain additional, more specific indications for use of our ClearPoint system beyond the general neurological intervention claim. Some of these expanded claims may require FDA 501(k) clearance. Other claims may require FDA approval of a PMA. Moreover, some specific ClearPoint system claims that we may seek may require clinical trials to support regulatory clearance or approval, and we may not successfully complete or have the funds to initiate these clinical trials. The FDA may not clear or approve these future claims or future generations of our ClearPoint system for the indications that are necessary or desirable for successful commercialization. Indeed, the FDA may refuse our requests for 510(k) clearance or PMA approval. Failure to receive clearance or approval for additional claims for our ClearPoint system would have an adverse effect on our ability to expand our business.

Clinical trials necessary to support 510(k) clearance or PMA approval for the ClearTrace system or any new indications for use for our ClearPoint system will be expensive and may require the enrollment of large numbers of suitable patients, who may be difficult to identify and recruit. Delays or failures in our clinical trials will prevent us from commercializing any modified or new product candidates and will adversely affect our business, operating results and prospects.

Initiating and completing clinical trials necessary to support a PMA for the ClearTrace system or any other product candidates that we may develop, or additional safety and efficacy data that the FDA may require for 510(k) clearance or PMA approval for any new specific indications of our ClearPoint system that we may seek, will be time consuming and expensive with an uncertain outcome. Moreover, the results of early clinical trials are not necessarily predictive of future results, and any product candidate we advance into clinical trials may not have favorable results in later clinical trials.

Conducting successful clinical trials may require the enrollment of large numbers of patients, and suitable patients may be difficult to identify and recruit. Patient enrollment in clinical trials and completion of patient participation and follow-up depends on many factors, including the size of the patient population, the nature of the trial protocol, the attractiveness of, or the discomforts and risks associated with, the treatments received by enrolled subjects, the availability of appropriate clinical trial investigators and support staff, the proximity to clinical sites of patients that are able to comply with the eligibility and exclusion criteria for participation in the clinical trial, and patient compliance. For example, patients may be discouraged from enrolling in our clinical trials if the trial protocol requires them to undergo extensive post-treatment procedures or follow-up to assess the safety and effectiveness of our product candidates or if they determine that the treatments received under the trial protocols are not attractive or involve unacceptable risks or discomforts. In addition, patients participating in clinical trials may die before completion of the trial or suffer adverse medical events unrelated to our product candidates.

Development of sufficient and appropriate clinical protocols to demonstrate safety and efficacy will be required and we may not adequately develop such protocols to support clearance or approval. Further, the FDA may require us to submit data on a greater number of patients than we originally anticipated and/or for a longer follow-up period or change the data collection requirements or data analysis applicable to our clinical trials. Delays in patient enrollment or failure of patients to continue to participate in a clinical trial may cause an increase in costs and delays in the approval and attempted commercialization of our product candidates or result in the failure of the clinical trial. Such increased costs and delays or failures could adversely affect our business, operating results and prospects.

If the third parties on which we may need to rely to conduct any clinical trials and to assist us with pre-clinical development do not perform as contractually required or expected, we may not be able to obtain regulatory clearance or approval for the ClearTrace system or any additional claims that we may seek for our ClearPoint system.

We do not have the independent ability to conduct pre-clinical and clinical trials for our marketed products or our product candidates. To the extent that we will need to conduct such trials, we will need to rely on third parties, such as contract research organizations, medical institutions, clinical investigators and contract laboratories, to conduct such trials. If these third parties do not successfully carry out their contractual duties or regulatory obligations or meet expected deadlines, if these third parties need to be replaced, or if the quality or accuracy of the data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our pre-clinical development activities or clinical trials may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory clearance or approval for a product candidate or additional claims we may seek for our marketed products on a timely basis, if at all. As such, our business, operating results and prospects may be adversely affected. Furthermore, our third-party clinical trial investigators may be delayed in conducting our clinical trials for reasons outside of their control.

The results of our clinical trials may not support our product candidate claims or any additional claims we may seek for our marketed products and may result in the discovery of adverse side effects.

Even if any clinical trial that we need to undertake is completed as planned, we cannot be certain that its results will support our product candidate claims or any new indications that we may seek for our marketed products or that the FDA or foreign authorities will agree with our conclusions regarding the results of those trials. The clinical trial process may fail to demonstrate that our marketed products or a product candidate is safe and effective for the proposed indicated use, which could cause us to stop seeking additional clearances or approvals for our ClearPoint system, abandon a product candidate and may delay development of others. Any delay or termination of our clinical trials will delay the filing of our regulatory submissions and, ultimately, our ability to commercialize a product candidate. It is also possible that patients enrolled in clinical trials will experience adverse side effects that are not currently part of the product candidate’s profile.

The markets for medical devices, such as our ClearPoint system and our product candidates, are highly competitive and we may not be able to compete effectively against the larger, well-established companies in our markets or emerging and small innovative companies that may seek to obtain or increase their share of the market.

We will face competition from products and techniques already in existence in the marketplace. The markets for our ClearPoint system and our product candidates are intensely competitive, and many of our competitors are much larger and have substantially more financial and human resources than we do. Many have long histories and strong reputations within the industry, and a relatively small number of companies dominate these markets. Examples of such large, well-known companies include Biosense Webster Inc., a division of Johnson & Johnson, Medtronic, Inc. and St. Jude Medical Inc.

These companies enjoy significant competitive advantages over us, including:

We may not succeed in overcoming the competitive advantages of these large and established companies. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These companies may introduce products that compete effectively against our products in terms of performance, price or both.

We could become subject to product liability claims that could be expensive, divert management’s attention and harm our business.

Our business exposes us to potential product liability risks that are inherent in the manufacturing, marketing and sale of medical devices. We may be held liable if our products cause injury or death or are found otherwise unsuitable or defective during usage. Our ClearPoint system and the ClearTrace system incorporate mechanical and electrical parts, complex computer software and other sophisticated components, any of which can have defective or inferior parts or contain defects, errors or failures. Complex computer software is particularly vulnerable to errors and failures, especially when first introduced.

Because our ClearPoint system and the ClearTrace system are designed to be used to perform complex surgical procedures, defects could result in a number of complications, some of which could be serious and could harm or kill patients. The adverse publicity resulting from any of these events could cause physicians or hospitals to review and potentially terminate their relationships with us.

The medical device industry has historically been subject to extensive litigation over product liability claims. A product liability claim, regardless of its merit or eventual outcome, could result in significant legal defense costs. Although we maintain product liability insurance, the coverage is subject to deductibles and limitations, and may not be adequate to cover future claims. Additionally, we may be unable to maintain our existing product liability insurance in the future at satisfactory rates or in adequate amounts. A product liability claim, regardless of its merit or eventual outcome could result in:

We may not realize the anticipated benefits from our collaborative agreement with Siemens regarding the ClearTrace system.

We have entered into a co-development agreement with Siemens to develop the hardware and MRI software necessary for the ClearTrace system. There can be no assurance that our co-development efforts will be successful or that we will complete development of the ClearTrace system hardware and MRI software. Under

our agreement, Siemens is responsible for developing the software for the ClearTrace system, and we are responsible for developing the catheters and other hardware, other than the MRI scanner and workstation. We are obligated to pay Siemens up to approximately $2,500,000 in milestone payments associated with Siemens’ successful development of the software in accordance with our specifications. We started making these payments in the second quarter of 2009 and will continue through the third quarter of 2011. Once the software for the ClearTrace system is commercially available, Siemens is obligated to pay us a fixed amount for each software license sold by Siemens until we recoup our investment in the software. However, if Siemens does not successfully commercialize the software, or if our agreement with Siemens is terminated, we may not recover our investment in the software.

We may not realize the anticipated benefits from our collaborative agreements with Boston Scientific regarding the SafeLead Development Program.

We entered into license and development agreements with Boston Scientific with respect to our MRI-safety technologies. We are working with Boston Scientific to incorporate our MRI-safety technologies into Boston Scientific’s implantable medical leads for cardiac and neurological applications. There is no assurance that our joint development efforts will be successful or that patents will issue on any patent applications we licensed to Boston Scientific, in which case we would not receive future milestone payments or royalties provided for under our agreements with Boston Scientific. Further, Boston Scientific has no obligation to include our licensed intellectual property in its product candidates. Even if Boston Scientific incorporates our licensed intellectual property into its product candidates, Boston Scientific may be unable to obtain regulatory clearance or approval or successfully commercialize the related products, in which case we would not receive royalties in the amounts that we currently anticipate.

We may be required to pay amounts to Boston Scientific under our development agreement in the neurological field if all of our development milestones under that agreement are not met by December 31, 2012.

Our development agreement with Boston Scientific in the neurological field requires specified milestones in the development of an MRI-safe implantable lead to be achieved by December 31, 2012. If the milestones are not achieved by that date, and this failure is not the result of Boston Scientific’s failure to reasonably cooperate with us in pursuing the milestones, we will be required to pay Boston Scientific a sum of money equal to all milestone payments previously paid to us by Boston Scientific under the development agreement, all development expense reimbursements previously paid to us by Boston Scientific under the development agreement, and all patent prosecution costs incurred by Boston Scientific with respect to the intellectual property licensed under the related license agreement. As of March 31, 2010, the potential obligation to Boston Scientific was approximately $750,000, plus costs incurred by Boston Scientific in prosecuting the licensed intellectual property. Our potential payment obligation to Boston Scientific under the neuro development agreement does not apply to any amounts we receive under our agreements in the cardiac field, including the $13,000,000 of upfront licensing fees and any development milestone payments. Our agreements with Boston Scientific in the cardiac field do not impose a payment obligation on us for failure to achieve development milestones.

Boston Scientific has the right to terminate our development agreement for implantable cardiac leads under specified circumstances.

Boston Scientific has the one-time option, within 60 days after successful completion of the first lead feasibility study for cardiac applications, to cease further development work and to terminate the development agreement. If Boston Scientific elects to exercise its termination option under the development agreement, the license we granted to Boston Scientific in that field of use will automatically become non-exclusive with respect to some intellectual property, other intellectual property will be removed from the scope of the license and all rights will revert to us, and Boston Scientific will not be obligated to pay us any future royalties based on sales of its products containing our intellectual property that remains subject to the non-exclusive license.

Risks Related to our Need for Financing

We may not be able to continue operations as a going concern and our stockholders may lose their entire investment in us.

At March 31, 2010 and December 31, 2009, we had cash and cash equivalents of approximately $3,549,000 and $2,569,000, respectively, and stockholders’ deficit of approximately $11,395,000 and $9,888,000, respectively. In addition, we had a net loss for the three months ended March 31, 2010 of approximately $2,516,000 and a net loss for the year ended December 31, 2009 of approximately $7,159,000.

As discussed in note 3 to our financial statements included elsewhere in this prospectus, our cumulative net loss since inception and the net losses we incurred in 2009, 2008 and 2007 raise substantial doubt that we will be able to continue operations as a going concern. Our independent auditors included an explanatory paragraph regarding the uncertainty of whether we will be able to continue operations as a going concern in their report on our financial statements for the year ended December 31, 2009. Our ability to continue as a going concern is dependent upon us generating cash flow sufficient to fund operations and reducing operating expenses. Our business plans may not be successful in addressing these issues. If we cannot continue as a going concern, our stockholders may lose their entire investment in us.

We may need additional funding to continue to commercialize our marketed products and to bring our product candidates to market and we may not be able to raise capital when needed, which would force us to delay, reduce or eliminate our product development programs or commercialization efforts.

We will require substantial future capital in order to continue to establish effective marketing and sales capabilities for our ClearPoint system and conduct the research and development and regulatory clearance and approval activities necessary to bring our product candidates to market. If we are unable to generate revenue, we do not expect our existing capital resources and the net proceeds from this offering to be sufficient to enable us to fund the completion of the development and commercialization of all of our product candidates. Excluding cash generated from sales of our marketed products, we believe that the net proceeds from this offering, our existing cash resources and interest on these funds will be sufficient to meet our projected operating requirements through the end of 2011. However, our operating plans may change, and we may need additional funds sooner than anticipated to meet our operational needs and capital requirements for product development, clinical trials, regulatory clearances and approvals, and product commercialization.

Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available on a timely basis, we may terminate or delay the development of one or more of our product candidates, or delay establishment of sales and marketing capabilities or other activities necessary to commercialize our product candidates successfully.

Our future funding requirements will depend on many factors, including:

17

Table of Contents

Index to Financial Statements

Raising additional capital by issuing securities or through collaborative or licensing arrangements may cause dilution to existing stockholders, restrict our operations or require us to relinquish proprietary rights.

To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a stockholder. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaboration or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability to achieve our product development and commercialization goals and have a material adverse effect on our business, financial condition and results of operations.

If we are unable to generate sufficient revenues from product sales, we may not have the funds to make required payments on certain of our convertible promissory notes.

During 2009, Boston Scientific loaned us $3,500,000 pursuant to the terms of three convertible promissory notes. Interest on the loans accrues at 10% per annum and compounds annually. The Boston Scientific loans are secured by a first priority security interest in all of our assets. Each loan matures on the second anniversary of the date on which the funds were advanced, which will occur in October, November and December of 2011, respectively. On June 16, 2010, we received 510(k) clearance from the FDA to market our ClearPoint system in the United States. While we recently began marketing in the United States by directly contacting key physicians and hospitals, we have not generated revenues from product sales. If we are unable to generate sufficient product revenues, we may not have the funds necessary to make the required interest and principal payments on the Boston Scientific loans when due. If we do not have sufficient funds to make these payments, we will seek an alternative source of funds, which may include sales of our assets or equity securities or additional borrowings. We cannot assure you that an alternative source of funds would be available on terms acceptable to us, or at all, which would have a material adverse effect on our financial condition.

Risks Related to our Intellectual Property

We are currently subject to intellectual property litigation. We may spend substantial funds to defend ourselves in the litigation and, if we are unsuccessful in our defense, we may be required to change our name and incur substantial additional costs, all of which could harm our operating results.

On April 22, 2010, SurgiVision Consultants, Inc. and Guy M. Kezirian filed a lawsuit against us in the United States District Court, Central District of California, alleging trademark infringement, unfair competition, trademark dilution and violation of the Anti-Cybersquatting Protection Act, all relating to our use of our SURGI- VISION and SURGIVISION trademarks and our www.surgivision.com domain name. The plaintiffs are seeking unspecified monetary damages and injunctive relief. This action is at a very preliminary stage. We believe that we have strong defenses to the allegations, and we intend to vigorously defend ourselves in the lawsuit to protect our rights. However, intellectual property litigation is inherently time consuming, expensive and unpredictable. If we are unsuccessful in the litigation, we may be required to change our name as well as pay monetary damages. If we are required to change our name, we may incur substantial costs and suffer from a loss of name recognition, which could harm our business, operating results and financial condition.

If we, or the third parties from whom we license intellectual property, are unable to secure and maintain patent or other intellectual property protection for the intellectual property covering our marketed products or our product candidates, our ability to compete will be harmed.

Our commercial success depends, in part, on obtaining patent and other intellectual property protection for the technologies contained in our marketed products and product candidates. The patent positions of medical

18

Table of Contents

Index to Financial Statements

device companies, including ours, can be highly uncertain and involve complex and evolving legal and factual questions. Our patent position is uncertain and complex, in part, because of our dependence on intellectual property that we license from others. If we, or the third parties from whom we license intellectual property, fail to obtain adequate patent or other intellectual property protection for intellectual property covering our marketed products or product candidates, or if any protection is reduced or eliminated, others could use the intellectual property covering our marketed products or product candidates, resulting in harm to our competitive business position. In addition, patent and other intellectual property protection may not provide us with a competitive advantage against competitors that devise ways of making competitive products without infringing any patents that we own or have rights to.

As of April 30, 2010, our portfolio included eight wholly-owned issued United States patents (including one design patent), 25 wholly-owned pending United States patent applications (including five provisional applications), four co-owned issued United States patents, nine co-owned pending United States patent applications, one wholly-owned issued foreign patent, 38 wholly-owned pending foreign patent applications (including seven Patent Cooperation Treaty applications), one co-owned issued foreign patent and 22 co-owned pending foreign patent applications (including one Patent Cooperation Treaty application). In addition, as of April 30, 2010, we had licensed rights to 11 United States and 15 foreign third-party issued patents, and we had licensed rights to nine United States and 12 foreign third-party pending patent applications. United States patents and patent applications may be subject to interference proceedings and United States patents may be subject to reissue and reexamination proceedings in the United States Patent and Trademark Office. Foreign patents may

be subject to opposition or comparable proceedings in the corresponding foreign patent offices. Any of these proceedings could result in either loss of the patent or denial of the patent application, or loss or reduction in the scope of one or more of the claims of the patent or patent application. Changes in either patent laws or in interpretations of patent laws may also diminish the value of our intellectual property or narrow the scope of our protection. Interference, reexamination and opposition proceedings may be costly and time consuming, and we, or the third parties from whom we license intellectual property, may be unsuccessful in such proceedings. Thus, any patents that we own or license may provide limited or no protection against competitors. In addition, our pending patent applications and those we may file in the future may not result in patents being issued or may have claims that do not cover our marketed products or product candidates. Even if any of our pending or future patent applications are issued, they may not provide us with adequate protection or any competitive advantages. Our ability to develop additional patentable technology is also uncertain.

Non-payment or delay in payment of patent fees or annuities, whether intentional or unintentional, may also result in the loss of patents or patent rights important to our business. Many countries, including certain countries in Europe, have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against third parties, including government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of the patent. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as do the laws of the United States, particularly in the field of medical devices and procedures.

Others may assert that our marketed products or product candidates infringe their intellectual property rights, which may cause us to engage in costly disputes and, if we are not successful in defending ourselves, could also cause us to pay substantial damages and prohibit us from selling our marketed products.

There may be United States and foreign patents issued to third parties that relate to our business, including MRI-guided intervention systems and the components and methods and processes related to these systems. Some of these patents may be broad enough to cover one or more aspects of our present technologies and/or may cover aspects of our future technologies. We do not know whether any of these patents, if asserted, would be held valid, enforceable and infringed.

We cannot assure that a court or administrative body would agree with any arguments or defenses we may have concerning invalidity, unenforceability or non-infringement of any third-party patent. In addition, other

19

Table of Contents

Index to Financial Statements

parties may have filed or may in the future file patent applications for products that are similar or identical to ours. We cannot assure that any patents issuing from applications filed by a third party will not cover our marketed products or product candidates or will not have priority over our patents or patent applications.

The medical device industry has been characterized by extensive litigation and administrative proceedings regarding patents and other intellectual property rights, and companies have employed such actions to gain a competitive advantage. If third parties assert infringement or other intellectual property claims against us, our technical and management personnel will experience a significant diversion of time and effort and we will incur large expenses defending our company. If third parties in any patent action are successful, our patent portfolio may be damaged, we may have to pay substantial damages and we may be required to stop selling our marketed products or obtain a license which, if available at all, may require us to pay substantial royalties. We cannot be certain that we will have the financial resources or the substantive arguments to defend our marketed products or product candidates from infringement or our patents from claims of invalidity or unenforceability, or to defend our marketed products or product candidates against allegations of infringement of third-party patents. In addition, any public announcements related to litigation or administrative proceedings initiated by us, or initiated or threatened against us, could cause our stock price to decline.

If we lose access to critical third-party software that is integrated into our ClearPoint system software, our costs could increase and sales of our ClearPoint system would be delayed, potentially hurting our competitive position.

We license software from a third party that is integrated into the software component of our ClearPoint system. Our license continues through July 2015. If we are unable to continue to license this third-party software, we would not be able to continue to commercialize our ClearPoint system until equivalent software could be identified, licensed or developed, and integrated into the software component of our ClearPoint system. These delays, if they occur, could harm our business, operating results and financial condition.

We may be subject to damages resulting from claims that our employees or we have wrongfully used or disclosed alleged trade secrets or other proprietary information of their former employers.

Many of our employees were previously employed at universities or other medical device companies, including competitors or potential competitors. In the future, we could be subject to claims that these employees, or we, have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. If we fail in defending against such claims, a court could order us to pay substantial damages and prohibit us from using technologies or features that are essential to our marketed products and product candidates, if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of the former employers. In addition, we may lose valuable intellectual property rights or personnel. A loss of key research personnel or their work product could hamper or prevent our ability to commercialize certain product candidates, which could severely harm our business. Even if we are successful in defending against these claims, such litigation could result in substantial costs and be a distraction to our employees and management.

If the combination of patents, trade secrets and contractual provisions that we rely on to protect our intellectual property is inadequate, our ability to successfully commercialize our marketed products and product candidates will be harmed, and we may not be able to operate our business profitably.

Our success and ability to compete is dependent, in part, upon our ability to maintain the proprietary nature of our technologies. We rely on a combination of patent, copyright, trademark and trade secret law and nondisclosure agreements to protect our intellectual property. However, such methods may not be adequate to protect us or permit us to gain or maintain a competitive advantage. Our patent applications may not issue as patents in a form that will be advantageous to us, or at all. Our issued patents, and those that may issue in the future, may be challenged, invalidated or circumvented, which could limit our ability to stop competitors from marketing related products.

To protect our proprietary rights, we may in the future need to assert claims of infringement against third  parties to protect our intellectual property. There can be no assurance that we will be successful on the merits in any enforcement effort. In addition, we may not have sufficient resources to litigate, enforce or defend our intellectual property rights. Litigation to enforce our intellectual property rights in patents, copyrights or trademarks is highly unpredictable, expensive and time consuming and would divert human and monetary resources away from managing our business, all of which could have a material adverse effect on our financial condition and results of operations even if we were to prevail in such litigation. In the event of an adverse judgment, a court could hold that some or all of our asserted intellectual property rights are not infringed, or that they are invalid or unenforceable, and could award attorney fees.

Despite our efforts to safeguard our unpatented and unregistered intellectual property rights, we may not be successful in doing so or the steps taken by us in this regard may not be adequate to detect or deter misappropriation of our technologies or to prevent an unauthorized third party from copying or otherwise obtaining and using our products, technologies or other information that we regard as proprietary. Additionally, third parties may be able to design around our patents. Furthermore, the laws of foreign countries may not protect our proprietary rights to the same extent as the laws of the United States. Our inability to adequately protect our intellectual property could allow our competitors and others to produce products based on our technologies, which could substantially impair our ability to compete.

We have entered into confidentiality and intellectual property assignment agreements with our employees and consultants as one of the ways we seek to protect our intellectual property and other proprietary technologies. However, these agreements may not be enforceable or may not provide meaningful protection for our trade secrets or other proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements.

Our employees and consultants may unintentionally or willfully disclose our confidential information to competitors, and confidentiality agreements may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. Enforcing a claim that a third party illegally obtained and is using our proprietary know-how is expensive and time-consuming, and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect know-how than courts in the United States. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how. Failure to obtain or maintain intellectual property protection could adversely affect our competitive business position.

We may be dependent upon one of our licenses from The Johns Hopkins University to develop and commercialize some components of the ClearTrace system.

We have entered into exclusive license agreements with The Johns Hopkins University, or Johns Hopkins, with respect to a number of technologies owned by Johns Hopkins. Under one of those agreements, which we entered into in 1998, we licensed a number of technologies relating to devices, systems and methods for performing MRI-guided interventions, particularly MRI-guided cardiac ablation procedures. Therefore, that license is important to the development of the ClearTrace system. Without that license, we may not be able to commercialize some of the components of the ClearTrace system when, and if, developed, subject to FDA clearance or approval. Johns Hopkins has the right to terminate the license under specified circumstances, including a breach by us and failure to cure such breach or in the event we file for bankruptcy. We are obligated to use commercially reasonable efforts to develop and commercialize products based on the licensed patents and patent applications. This obligation could require us to take actions related to the development of the ClearTrace system that we would otherwise not take.

Risks Related to Regulatory Compliance

We operate in a highly-regulated industry and any failure to comply with the extensive government regulations may subject us to fines, injunctions and other penalties that could harm our business.

Our marketed products, our product candidates and operations are subject to extensive regulation by the FDA and various other federal, state and foreign governmental authorities. Government regulations and foreign requirements specific to medical devices are wide ranging and govern, among other things:

We are subject to ongoing FDA requirements, including: required submissions of safety and other post-market information; manufacturing facility registration and device listing requirements; compliance with FDA’s medical device current Good Manufacturing Practice regulations, as codified in the Quality System Regulation, or QSR; requirements regarding field corrections and removals of our marketed products; reporting of adverse events and certain product malfunctions to the FDA; and numerous recordkeeping requirements. If we or any of our collaborators or suppliers fail to comply with applicable regulatory requirements, a regulatory agency may take action against us, including any of the following sanctions:

The FDA’s and foreign regulatory agencies’ statutes, regulations or policies may change, and additional government regulation or statutes may be enacted, which could increase post-approval regulatory requirements, or delay, suspend or prevent marketing of our marketed products. We cannot predict the likelihood, nature or extent of adverse governmental regulation that might arise from future legislative or administrative action, either in the United States or abroad.

22

Table of Contents

Index to Financial Statements

If we or our third-party suppliers fail to comply with the FDA’s QSR or any applicable state equivalent, our manufacturing operations could be interrupted and our potential product sales and operating results could suffer.

We and some of our third-party suppliers are required to comply with the FDA’s QSR, which covers the methods and documentation of the design, testing, production, control, quality assurance, labeling, packaging, sterilization, storage and shipping of our marketed products and product candidates. We and our suppliers will also be subject to the regulations of foreign jurisdictions regarding the manufacturing process if we market our products in these jurisdictions. The FDA enforces the QSR through periodic and unannounced inspections of manufacturing facilities. Our facilities have not been inspected by the FDA for QSR compliance. We anticipate that we and certain of our third-party suppliers will be subject to future inspections. The failure by us or one of our third-party suppliers to comply with applicable statutes and regulations administered by the FDA and other regulatory bodies, or the failure to timely and adequately respond to any adverse inspectional observations, could result in enforcement actions against us, which could impair our ability to produce our marketed products in a cost-effective and timely manner in order to meet our customers’ demands. If we fail to comply with the FDA’s QSR or any applicable state equivalent, we would be required to incur the costs and take the actions necessary to bring our operations into compliance, which may have a negative impact on our future sales and our ability to generate a profit.

Our marketed products may in the future be subject to product recalls that could harm our reputation, business operations and financial results.

The FDA and similar foreign governmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design, manufacture or labeling. In the case of the FDA, the authority to require a recall must be based on an FDA finding that there is a reasonable probability that the device would cause serious injury or death. In addition, foreign governmental bodies have the authority to require the recall of our marketed products in the event of material deficiencies or defects in design or manufacture. Manufacturers may, under their own initiative, recall a product if any material deficiency in a device is found. A government-mandated or voluntary recall by us could occur as a result of component failures, manufacturing errors, design or labeling defects or other deficiencies and issues. Recalls of any of our marketed products would divert managerial and financial resources and have an adverse effect on our financial condition and results of operations. We may initiate certain voluntary recalls involving our marketed products in the future. Companies are required to maintain certain records of recalls, even if they are not reportable to the FDA. If we determine that certain of those recalls do not require notification to the FDA, the FDA may disagree with our determinations and require us to report those actions as recalls. A future recall announcement could harm our reputation with customers and negatively affect our sales. In addition, the FDA could take enforcement actions against us, which could impair our ability to produce our marketed products in a cost-effective and timely manner in order to meet our customers’ demands. Regulatory investigations or product recalls could also result in our incurring substantial costs, losing revenues and implementing a change in the design, manufacturing process or the indications for which our products may be used, each of which would harm our business.

If our marketed products cause or contribute to a death or a serious injury, or malfunction in certain ways, we will be subject to medical device reporting regulations, which can result in voluntary corrective actions or agency enforcement actions.

Under the FDA’s medical device reporting regulations, we are required to report to the FDA any incident in which our marketed products may have caused or contributed to a death or serious injury or in which our marketed products malfunctioned and, if the malfunction were to recur, would likely cause or contribute to death or serious injury. In the future, we may experience events that may require reporting to the FDA pursuant to the medical device reporting regulations. In addition, all manufacturers placing medical devices in European Union markets are legally bound to report any serious or potentially serious incidents involving devices they produce or sell to the relevant authority in whose jurisdiction the incident occurred. Any adverse event involving our

23

Table of Contents

Index to Financial Statements

marketed products could result in future voluntary corrective actions, such as recalls or customer notifications, or agency action, such as inspection, mandatory recall or other enforcement action. Any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will require the dedication of our time and capital, distract management from operating our business, and may harm our reputation and financial results. In addition, failure to report such adverse events to appropriate government authorities on a timely basis, or at all, could result in an enforcement action against us.

We may incur significant liability if it is determined that we are promoting off-label uses of our products in violation of federal and state regulations in the United States or elsewhere.

We obtained 510(k) clearance of our ClearPoint system from the FDA for a general neurological intervention claim. This general neurological intervention indication is the same indication for use that applies to other devices that have traditionally been used in the performance of stereotactic neurological procedures, under which a physician merges pre-operative images and data with specialized surgical instruments to help guide the procedure. Our business and future growth, however, may depend substantially on the use or enhancement of our ClearPoint system in deep brain stimulation lead placement procedures. In the future, we may seek regulatory clearance or approval, as the case may be, for use of our ClearPoint system for a variety of specific neurological indications, including deep brain stimulation lead placement, to allow us to market and promote our ClearPoint system for those specific uses. Unless and until we receive regulatory clearance or approval for use of our ClearPoint system in these specific procedures, uses in procedures other than general neurological intervention procedures, such as biopsies and catheter and electrode insertion, may be considered off-label uses of our ClearPoint system.

Under the federal Food, Drug, and Cosmetic Act and other similar laws, we are prohibited from labeling or promoting our ClearPoint system, or training physicians, for such off-label uses. The FDA defines labeling to include not only the physical label attached to the product, but also items accompanying the product. This definition also includes items as diverse as materials that appear on a company’s website. As a result, we are not permitted to promote uses of our marketed products that are not cleared or approved, whether on our website, in product brochures or in customer communications. This prohibition means that the FDA could deem it unlawful for us to make claims about the use of our ClearPoint system specifically for deep brain stimulation lead placement procedures or proactively discuss or provide information or training on the use of our ClearPoint system specifically for deep brain stimulation lead placement procedures. However, although manufacturers are not permitted to promote for off-label uses, in their practice of medicine, physicians may lawfully choose to use medical devices for off-label uses. Therefore, a physician could use our ClearPoint system for uses not covered by the cleared labeling. This would constitute an off-label use. We expect that physicians will use our ClearPoint system for a variety of specific neurological procedures, including deep brain stimulation lead placement.

The FDA and other regulatory agencies actively enforce regulations prohibiting promotion of off-label uses and the promotion of products for which marketing clearance or approval has not been obtained. If the FDA determines that our promotional materials or training constitutes promotion of an off-label use, it could request that we modify our training or promotional materials or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, warning letter, injunction, seizure, civil fine and criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our promotional or training materials to constitute promotion of an unapproved use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. In that event, our reputation could be damaged and market adoption of our marketed products would be impaired. Due to these legal constraints, our sales and marketing efforts will focus only on the general technical attributes and benefits of our ClearPoint system and the FDA cleared indications for use. In addition, the off-label use of our marketed products may increase the risk of injury to patients, and, in turn, the risk of product liability claims. Product liability claims are expensive to defend and could divert our management’s attention and result in substantial damage awards against us.

We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws and regulations and could face substantial penalties if we are unable to fully comply with such laws.

Although we do not provide healthcare services or receive payments directly from Medicare, Medicaid or other third-party payors for our marketed products or the procedures in which our marketed products may be used, many state and federal healthcare laws and regulations governing financial relationships between medical device companies and healthcare providers apply to our business and we could be subject to enforcement by both the federal government, private whistleblowers and the states in which we conduct our business. The healthcare laws and regulations that may affect our ability to operate include:

Recently, the medical device industry has been under heightened scrutiny as the subject of government investigations and government enforcement or private whistleblower actions under the Anti-Kickback Statute and the False Claims Act involving manufacturers who allegedly offered unlawful inducements to potential or existing customers in an attempt to procure their business, including specifically arrangements with physician consultants. For example, in 2007, four of the five major orthopedic implant manufacturers were required to pay a total of $311 million and operate for 18 months under federal court supervision in settlement of kickback allegations concerning their physician consulting contracts.

We have a number of agreements with physicians that may be scrutinized or may be subject to reporting requirements in the future, including consulting contracts for product development in which we compensate physicians for various services, including:

We may enter into similar consulting agreements with physicians in the future. Likewise, we may enter into consulting agreements with physicians to provide training and other similar services on the proper use of our marketed products.

The Health Care Reform Law mandates increased transparency of arrangements between physicians and medical device companies, which we expect will increase our overall cost of compliance. We believe that this increased transparency will also result in a heightened level of government scrutiny of the relationships between physicians and medical device companies. While we believe that all of our arrangements with physicians comply with applicable law, the increased level of scrutiny, coupled with the expanded enforcement tools available to the government under the Health Care Reform Law, may increase the likelihood of a governmental investigation. If we become subject to such an investigation, our business and operations would be adversely affected even if we ultimately prevail because the cost of defending such investigation would be substantial. Moreover, companies subject to governmental investigations could lose both overall market value and market share during the course of the investigation.

In addition, we may provide customers with information on products that could be deemed to influence their coding or billing practices, and may have sales, marketing or other arrangements with hospitals and other providers that could also be the subject of scrutiny under these laws. If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from the Medicare and Medicaid programs and the curtailment or restructuring of our operations. Any penalties, damages, fines, exclusions, curtailment or restructuring of our operations could adversely affect our ability to operate our business and our financial results. The risk of our being found in violation of these laws is increased by the fact that many of these laws are broad and their provisions are open to a variety of interpretations. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. If the surgeons or other providers or entities with whom we do business are found to be non-compliant with applicable laws, they may be subject to sanctions, which could also have a negative impact on our business.

We may be subject to privacy and data protection laws governing the transmission, security and privacy of health information which may impose restrictions on technologies and subject us to penalties if we are unable to fully comply with such laws.

Numerous federal, state and international laws and regulations govern the collection, use, disclosure, storage and transmission of patient-identifiable health information. These laws include:

Index to Financial Statements

We are required to comply with federal and state laws governing the transmission, security and privacy of patient identifiable health information that we may obtain or have access to in connection with manufacture and sale of our marketed products. We do not believe that we are a HIPAA covered entity because we do not submit electronic claims to third-party payors, but there may be limited circumstances in which we may operate as a business associate to covered entities if we receive patient identifiable data through activities such as training providers on the use of our marketed products or investigating product performance or if our marketed products store patient identifiable health information on behalf of a healthcare provider. We may be required to make costly system modifications to comply with the HIPAA privacy and security requirements that will be imposed on us contractually through business associate agreements by covered entities and directly under HITECH provisions that became effective in February 2010. Due to the recent enactment of HITECH, we are not able to predict what the extent of the impact on our business may be. Our failure to comply may result in criminal and civil liability because the potential for enforcement action against business associates is now greater. Enforcement actions can be costly and interrupt regular operations which may adversely affect our business.

In addition, numerous other federal and state laws protect the confidentiality of patient information as well as employee personal information, including state medical privacy laws, state social security number protection laws and federal and state consumer protection laws. These various laws in many cases are not preempted by the HIPAA rules and may be subject to varying interpretations by the courts and government agencies, creating complex compliance issues for us and our customers and potentially exposing us to additional expense, adverse publicity and liability.

In connection with any clinical trials we conduct, we will be subject to state and federal privacy and human subject protection regulations. The HIPAA requirement and other human subjects research laws could create liability for us or increase our cost of doing business because we must depend on our research collaborators to comply with the applicable laws. We may adopt policies and procedures that facilitate our collaborators’ compliance, but we cannot ensure that non-employee collaborators or investigators will comply with applicable laws. As a result, unauthorized uses and disclosures of research subject information in violation of the law may occur. These violations may lead to sanctions that will adversely affect our business.

Risks Related to Facilities, Employees and Growth

We are dependent on our senior management team, engineering team, sales and marketing team and key research and physician advisors, and the loss of any of them could harm our business.

We are highly dependent on members of our senior management, in particular Kimble L. Jenkins, our President, Chief Executive Officer and Chairman of the Board of Directors, and Peter G. Piferi, our Chief Operating Officer. The loss of members of our senior management team, engineering team, sales and marketing team and key research and physician advisors, or our inability to attract or retain other qualified personnel or advisors, could have a material adverse effect on our business, financial condition and results of operations. We do not maintain key employee life insurance on any of our personnel other than for Mr. Jenkins and Mr. Piferi. Although we have obtained key employee insurance covering Mr. Jenkins and Mr. Piferi in the amount of $2,000,000, this would not fully compensate us for the loss of Mr. Jenkins’ or Mr. Piferi’s services.

We adopted our Key Personnel Incentive Plan, which is described in more detail on page 112, to provide Dr. Paul Bottomley, who is a key research advisor, and Mr. Parag Karmarkar, who is a key member of our engineering team, the opportunity to receive incentive bonus payments based on future performance of services to us or upon a sale of our company. However, if Dr. Bottomley or Mr. Karmarkar dies, becomes disabled or is involuntarily terminated by us without cause, we nevertheless would be obligated to make the incentive bonus payments otherwise provided under the plan. The obligation to make these payments could have a material adverse effect on our financial position. We may obtain life insurance on Dr. Bottomley and Mr. Karmarkar to reduce our financial exposure in the event of a participant’s death. We also adopted the Cardiac EP Business Participation Plan, which is described in more detail on page 112, to provide Dr. Nassir Marrouche, who is a key product development advisor, with financial rewards in the event that we sell our business operations relating to catheter-based MRI-guided cardiac ablation to treat cardiac arrhythmias, which we refer to as our cardiac EP business operations. If we sell our cardiac EP business operations or our entire company, we will be required to make a payment to Dr. Marrouche which is calculated as a percentage of the purchase price paid for, or allocated to, our cardiac EP business operations.

We need to hire and retain additional qualified personnel to grow and manage our business. If we are unable to attract and retain qualified personnel, our business and growth could be seriously harmed.

Our performance depends on the talents and efforts of our employees. Our future success will depend on our ability to attract, retain and motivate highly skilled personnel in all areas of our organization. We plan to continue to grow our business and will need to hire additional personnel to support this growth. We believe that there are only a limited number of individuals with the requisite skills to serve in many of our key positions, and we compete for key personnel with other medical device companies, as well as universities and research institutions. It is often difficult to hire and retain these persons, and we may be unable to replace key persons if they leave or fill new positions requiring key persons with appropriate experience. If we experience difficulties locating and hiring suitable personnel in the future, our growth may be hindered. Qualified individuals are in high demand, particularly in the medical device industry, and we may incur significant costs to attract and retain them. Employees that hold shares of our common stock or options to purchase our common stock may be more likely to leave us following our initial public offering as a result of the establishment of a public market for our common stock. If we are unable to attract and retain the personnel we need to succeed, our business and growth could be harmed.

If we do not effectively manage our growth, we may be unable to successfully develop, market and sell our products.

Our future revenue and operating results will depend on our ability to manage the anticipated growth of our business. In order to achieve our business objectives, we must continue to grow. However, continued growth presents numerous challenges, including:

We cannot be certain that our systems, controls, infrastructure and personnel will be adequate to support our future operations. Any failure to effectively manage our growth could impede our ability to successfully develop, market and sell our products and our business will be harmed.

Our operations are vulnerable to interruption or loss due to natural disasters, power loss and other events beyond our control, which would adversely affect our business.

We will conduct a significant portion of our activities, including component processing, final assembly, packaging and distribution activities for our ClearPoint system, at a facility located in Irvine, California, which is a seismically active area that has experienced major earthquakes in the past, as well as other natural disasters, including wildfires. We have taken precautions to safeguard our facility, including obtaining business interruption insurance. However, any future natural disaster, such as an earthquake or a wildfire, could significantly disrupt our operations, and delay or prevent product assembly and shipment during the time required to repair, rebuild or replace our facility, which could be lengthy and result in significant expenses. Furthermore, the insurance coverage we maintain may not be adequate to cover our losses in any particular case or continue to be available at commercially reasonable rates and terms. In addition, our facility may be subject to shortages of electrical power, natural gas, water and other energy supplies. Any future shortage or conservation measure could disrupt our operations and cause expense, thus adversely affecting our business and financial results.

Risks Related to this Offering

An active trading market for our common stock may not develop.

Prior to this offering, there has been no public market for our common stock. We have been approved for listing on the Nasdaq Capital Market; however, an active trading market for our shares may never develop or be sustained following this offering. Accordingly, you may not be able to sell your shares quickly or at the market price if trading in our stock is not active.

Market volatility may cause our stock price and the value of your investment to decline.

The initial public offering price for our common stock was determined through negotiations between the underwriters and us. The initial public offering price may vary from the market price of our common stock after the closing of this offering. Investors may not be able to sell their common stock at or above the initial public offering price.

We expect that the price of our common stock will fluctuate substantially, as the market price for our common stock after this offering will be affected by a number of factors, including:

In addition, the stock prices of many companies in the medical device industry have experienced wide fluctuations that have often been unrelated to the operating performance of these companies. We expect our stock price to be similarly volatile. These broad market fluctuations may continue and could harm our stock price. Following periods of volatility in the market price of a company’s securities, stockholders have often instituted class action securities litigation against those companies. Class action securities litigation, if instituted against us, could result in substantial costs and a diversion of our management resources, which could significantly harm our business.

Securities analysts may not initiate coverage for our common stock or may issue negative reports, and this may have a negative impact on the market price of our common stock.

Securities analysts may elect not to provide research coverage of our common stock after the completion of this offering. The lack of research coverage may adversely affect the market price of our common stock. The trading market for our common stock may be affected in part by the research and reports that industry or financial analysts publish about us or our business. It may be difficult for companies such as ours, with smaller market capitalizations, to attract securities analysts that will cover our common stock. If one or more of the

30

Table of Contents

Index to Financial Statements

analysts who elects to cover us downgrades our stock, our stock price would likely decline rapidly. If one or more of these analysts ceases coverage of our company, we could lose visibility in the market, which in turn could cause our stock price to decline. This could have a negative effect on the market price of our stock.

Our directors, executive officers and principal stockholders and their respective affiliates will continue to have substantial control over us after this offering and could delay or prevent a change in corporate control.

After this offering, our directors, executive officers and holders of more than 5% of our common stock, together with their affiliates, will beneficially own, in the aggregate, approximately 23.4% of our outstanding common stock. As a result, these stockholders, acting together, will continue to have substantial control over the outcome of matters submitted to our stockholders for approval, including the election of directors and any merger, consolidation or sale of all or substantially all of our assets. In addition, these stockholders, acting together, will continue to have significant influence over the management and affairs of our company. Accordingly, this concentration of ownership may have the effect of:

We have not paid dividends in the past and do not expect to pay dividends in the future.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all future earnings for the operation and expansion of our business and, therefore, do not anticipate declaring or paying cash dividends in the foreseeable future. The payment of dividends will be at the discretion of our Board of Directors and will depend on our results of operations, capital requirements, financial condition, prospects, contractual arrangements, any limitations on payments of dividends present in any of our future debt agreements and other factors our Board of Directors may deem relevant. If we do not pay dividends, a return on your investment will only occur if our stock price appreciates.

Anti-takeover provisions in our certificate of incorporation, bylaws and Delaware law could prevent or delay a change in control of our company.

Provisions in our certificate of incorporation and bylaws, which will be effective upon the closing of this offering, as well as provisions of Delaware law, may discourage, delay or prevent a merger, acquisition or change of control. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors and take other corporate actions. These provisions:

31

Table of Contents

Index to Financial Statements

In addition, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any broad range of business combinations with any stockholder who owns, or at any time in the last three years owned, 15% or more of our outstanding voting stock for a period of three years following the date on which the stockholder became an interested stockholder. This provision could have the effect of delaying or preventing a change of control, whether or not it is desired by or beneficial to our stockholders.

Sales of a substantial number of shares of our common stock in the public market after this offering, or the perception that they may occur, may depress the market price of our common stock.

Sales of substantial amounts of our common stock in the public market following this offering, or the perception that substantial sales may be made, could cause the market price of our common stock to decline. The lock-up agreements to be delivered by our executive officers, directors and certain of our stockholders provide that the underwriters, acting jointly and in their discretion, may release those parties, at any time, or from time to time, and without notice, from their obligation not to dispose of shares of common stock for a period of 180 days after the date of this prospectus, which period may be extended in certain limited circumstances. The underwriters do not have any pre-established conditions to waiving the terms of the lock-up agreements, and any decision by them to waive those conditions would depend on a number of factors, which may include market conditions, the performance of the common stock in the market and our financial condition at that time.

Based on the number of shares of common stock outstanding as of April 30, 2010, upon completion of this offering, 10,129,405 shares of our common stock will be outstanding. All of the shares sold in this offering will be freely transferable unless held by an affiliate of ours. Of the remaining shares, during the 90 days following the date of this prospectus, 1,965,521 shares held by non-affiliates, or approximately 19.4% of our common stock outstanding after this offering, will be freely transferable subject to compliance with Rule 144. Beginning on the 91st day following the date of this prospectus, 2,474,396 shares of our common stock, or approximately 24.4% of our common stock outstanding after this offering, will be freely transferable subject to compliance with Rule 144 under the Securities Act. The lockup agreements between the underwriters and our directors, executive officers and certain of our stockholders will expire 180 days after the date of this prospectus, at which time all of our shares of our common stock will be freely transferable subject to compliance with the provisions of Rule 144 under the Securities Act. See “Shares Eligible for Future Sale—Lock-up Agreements.” Our affiliates must comply with the volume, manner of sale, holding period and other limitations of Rule 144. As restrictions on resale end, the market price could drop significantly if the holders of these restricted shares sell them or are perceived by the market as intending to sell them. Any substantial sale of common stock pursuant to any resale registration statements or Rule 144 may have an adverse effect on the market price of our common stock by creating an excessive supply.

We intend to file a registration statement on Form S-8 to register the 1,850,625 shares subject to outstanding options or reserved for issuance under our stock option plans. The registration statement will become effective

when filed, and, subject to applicable lock-up agreements, if any, these shares may be resold without restriction in the public marketplace. For a more detailed description, please see the section of this prospectus entitled “Shares Eligible for Future Sale.”

New investors in our common stock will experience immediate and substantial dilution after this offering.

If you purchase shares of our common stock in this offering, you will experience immediate dilution of $11.90 per share based on the mid-point of the range on the cover of this prospectus because the price that you pay will be substantially greater than the adjusted pro forma net tangible book value per share of common stock that you acquire. This dilution is due in large part to the fact that many of our earlier investors paid substantially less than the price of the shares being sold in this offering when they purchased their shares of our capital stock. If outstanding options and warrants to purchase our common stock are exercised, you will experience additional dilution. See the section entitled “Dilution” in this prospectus for a more detailed description of this dilution.

We will incur significant increased costs as a result of operating as a public company, and our management will be required to divert attention from product development and commercialization and to devote substantial resources and time to new compliance initiatives.

As a public company, we will incur significant legal, accounting and other expenses that we did not incur as a private company. We are working with our independent legal and accounting advisors to identify those areas in which changes should be made to our financial and management control systems to manage our growth and our obligations as a public company. These areas include corporate control, disclosure controls and procedures and financial reporting and accounting systems, including requirements under the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act. We will incur costs associated with our public company reporting requirements and corporate governance requirements, including requirements under the Sarbanes-Oxley Act, as well as rules implemented by the SEC and the securities exchange on which our stock trades. We will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly. For example, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified people to serve on our Board of Directors, our board committees or as executive officers.

In addition, the Sarbanes-Oxley Act requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, for the fiscal year ending December 31, 2010, we must perform system and process evaluation and testing of our internal control over financial reporting to allow management and our independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. Our compliance with Section 404 will require that we incur substantial expense and expend significant management time on compliance-related issues.

We may not use the net proceeds from this offering effectively.

We intend to use the net proceeds from this offering in the manner described in “Use of Proceeds” elsewhere in this prospectus. Our use of the net proceeds of the offering in this manner will not necessarily improve our operating results or enhance the value of our common stock. The failure by our management to apply these funds effectively could result in financial losses, cause the price of our common stock to decline or delay product development.

USE OF PROCEEDS

We estimate that our net proceeds from the sale of 2,500,000 shares of common stock in this offering will be approximately $30,600,000 and an additional $4,800,000 if the underwriters exercise their over-allotment option in full, based upon an assumed initial public offering price of $14.00 per share, which is the mid-point of the range listed on the cover of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. The principal purposes of this offering are to obtain additional capital and to create a public market for our common stock.

A $1.00 increase (decrease) in the assumed initial public offering price of $14.00 per share would increase (decrease) the net proceeds to us from this offering by approximately $2,325,000, assuming the number of shares offered by us, as set forth on the cover of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

We expect to use between approximately $12,000,000 and $16,000,000 of the net proceeds from this offering to fund our research and development activities, including payments of approximately $2,200,000 to Siemens in connection with the development of the ClearTrace system software, which is only a portion of the estimated remaining development costs of the ClearTrace system, between approximately $6,500,000 and $9,500,000 to fund our sales and marketing activities and the remainder for working capital and general corporate purposes. In addition, we may use a portion of the net proceeds from this offering to acquire equipment, products or technologies, although we currently have no commitments or agreements relating to any of these types of transactions. Excluding cash generated from sales of our marketed products, we believe that the net proceeds from this offering, our existing cash resources and interest on these funds will be sufficient to meet our projected operating requirements through the end of 2011.

Pending these uses, we plan to invest the net proceeds in a variety of capital preservation instruments, including short-term, interest bearing obligations, investment grade instruments, certificates of deposit or direct or guaranteed obligations of the United States. The goal with respect to the investment of these net proceeds is capital preservation and liquidity so that such funds are readily available to fund our research and development operations.

DIVIDEND POLICY

We have never declared or paid any cash dividends on our capital stock. We currently intend to retain any future earnings to fund the development and expansion of our business, and therefore we do not anticipate paying cash dividends on our common stock in the foreseeable future. Any future determination to pay dividends will be at the discretion of our Board of Directors.

DILUTION

The historical net tangible book value of our common stock as of March 31, 2010 was approximately $(12,597,000), or $(2.46) per share, based on the number of shares of common stock outstanding as of March 31, 2010. Historical net tangible book value per share is determined by dividing our total tangible assets less total liabilities by the actual number of outstanding shares of our common stock. The pro forma net tangible book value of our common stock as of March 31, 2010 was approximately $(9,340,000), or $(1.22) per share. Pro forma net tangible book value per share is determined by dividing (x) our total tangible assets less total liabilities by (y) the actual number of outstanding shares of our common stock plus the number of shares issuable upon conversion of all of our outstanding shares of preferred stock and bridge notes into common stock as if such conversion had occurred on March 31, 2010 after giving effect to a 1-for-4 reverse stock split as if it had occurred prior to March 31, 2010.

After giving effect to the sale of common stock offered in this offering at the assumed public offering price of $14.00 per share, and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of March 31, 2010 would have been approximately $21,279,000, or $2.10 per share of common stock. This represents an immediate increase in pro forma as adjusted net tangible book value of $3.32 per share to existing stockholders and an immediate dilution of $11.90 per share to new investors purchasing our common stock in this offering. The following table illustrates this per share dilution to the new investors:

The following table summarizes, on a pro forma as adjusted basis as of March 31, 2010, the differences between the number of shares of common stock purchased from us, the total consideration and the average price per share paid by existing stockholders and by the investors participating in this offering, before deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, at an assumed initial public offering price of $14.00 per share, which is the mid-point of the range listed on the cover of this prospectus:

The number of shares of common stock outstanding in the table above is based on the pro forma number of shares outstanding as of March 31, 2010 which includes the assumed conversion of all of our outstanding shares of preferred stock and bridge notes into common stock, and assumes no exercise of the underwriters’over-allotment option. If the underwriters’ over-allotment option is exercised in full, the number of shares of common stock held by existing stockholders will be reduced to 72.6% of the total number of shares of common stock to be outstanding after this offering, and the number of shares of common stock held by investors participating in this offering will be increased to 2,875,000 shares or 27.4% of the total number of shares of common stock to be outstanding after this offering.

The following table summarizes, as of March 31, 2010 , after giving effect to the exercise of all stock options, warrants and convertible promissory notes outstanding as of March 31, 2010 as well as the assumed conversion of all of our outstanding shares of preferred stock and bridge notes into common stock, the differences between the number of shares of common stock purchased from us, the total consideration and the weighted average price per share paid by existing stockholders and by investors participating in this offering at an assumed initial public offering price of $14.00 per share, which is the mid-point of the range listed on the cover of this prospectus, before deducting underwriting discounts and commissions and estimated offering expenses:

Subsequent to March 31, 2010, we adopted our 2010 Incentive Compensation Plan, under which an aggregate of 1,250,000 shares of our common stock are reserved for issuance. To the extent that any outstanding options or warrants are exercised, new options are issued and those options are exercised or we issue additional shares of common stock in the future, there may be further dilution to investors participating in this offering.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read together with our financial statements and related notes included elsewhere in this prospectus. This discussion and analysis contains forward-looking statements that are based upon current expectations and involve risks, assumptions and uncertainties. You should review the “Risk Factors” section beginning on page 7 of this prospectus for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements described in the following discussion and analysis.

Overview

We are a medical device company focused on the development and commercialization of technology that enables physicians to see inside the brain and heart using direct, intra-procedural MRI guidance while performing minimally invasive surgical procedures. Utilizing hospitals’ existing MRI suites, we believe that our marketed products and our product candidates will deliver better patient outcomes in shorter procedure times, enhance revenue potential for both physicians and hospitals, and reduce costs to the healthcare system. Our ClearPoint system is designed to allow minimally invasive procedures in the brain to be performed in the hospital’s MRI suite. The ClearTrace system is designed to allow catheter-based minimally invasive procedures in the heart to be performed in the hospital’s MRI suite. Finally, under our SafeLead Development Program, we are working with Boston Scientific to incorporate our MRI-safety technologies into Boston Scientific’s implantable leads for cardiac and neurological applications.

On June 16, 2010 we received regulatory clearance from the FDA to market our ClearPoint system in the United States for general neurological procedures. As such, our financial statements do not reflect any revenues generated from sales of our ClearPoint system products. We do not have regulatory clearance or approval to sell the ClearTrace system and, therefore, we have not generated revenues from sales of that product candidate. In 2008, we received licensing fees totaling $13,000,000 from Boston Scientific for our MRI-safety technologies, which we used to finance our operations and internal growth. We have also financed our operations and internal growth through private placements of securities, borrowings and interest earned on the net proceeds from our private placements and the Boston Scientific licensing fees. Prior to 2008, we were a development stage enterprise. We have incurred significant losses since our inception in 1998 as we have devoted substantially all of our efforts to research and development. As of March 31, 2010, we had an accumulated deficit of approximately $44,539,000. We may continue to incur significant operating losses as we commercialize our marketed products, continue to develop our product candidates and expand our business generally. We also expect that our general and administrative expenses will increase due to additional operational and regulatory costs and burdens associated with operating as a public company.

Recent Developments

No material development has occurred since the conclusion of our quarterly period ended March 31, 2010 with the exception of our receipt of FDA clearance to market our ClearPoint system, which is discussed elsewhere in this prospectus.

Factors Which May Influence Future Results of Operations

The following is a description of factors which may influence our future results of operations, including significant trends and challenges that we believe are important to an understanding of our business and results of operations.

Revenues

Since inception, we have generated revenues primarily from our collaborative agreements with Boston Scientific, principally from recognition of portions of the $13,000,000 of licensing fees, which we received in

2008. Revenues associated with these licensing fees are recognized on a straight-line basis over a five year period, which is our estimated period of continuing involvement in the development activities. Additional payments related to substantive, performance-based milestones and incentive payments that may be received under the agreement regarding implantable cardiac leads will be deferred upon receipt and achievement of the specified milestones and recognized over our estimated period of continuing involvement. These revenue recognition policies are more fully described in the “Critical Accounting Policies and Significant Judgments and Estimates” section below. We did not report any revenues in 2007, 2006 or 2005.

On June 16, 2010 we received 510(k) clearance from the FDA to market our ClearPoint system in the United States for general neurological procedures. Future revenues from sales of our marketed products are difficult to predict and may not be sufficient to offset our continuing and increasing research and development expenses and selling, general and administrative expenses for the next several years. We cannot sell any of our product candidates until we receive regulatory clearance or approval.

The generation of recurring revenues through sales of our disposable components is an important part of our business model for our ClearPoint system. We anticipate that recurring revenues will constitute an increasing percentage of our total revenues as we leverage each new installation of our ClearPoint system to generate recurring sales of these disposable components. With respect to a single hospital, we do not anticipate that sales of the reusable components of our ClearPoint system will generate recurring revenues.

Research and Development Expenses

Our research and development expenses consist primarily of costs associated with the conceptualization, design, testing and prototyping of our ClearPoint system products and our product candidates. This includes: the salaries, travel and benefits of research and development personnel; materials and laboratory supplies used by our research personnel; consultant costs; sponsored contract research and product development with third parties; and licensing costs. From our inception through March 31, 2010, we have incurred approximately $26,983,000 in research and development expenses. We anticipate that research and development expenses will increase as we: (i) continue to develop enhancements to our ClearPoint system; (ii) continue our early-stage product development efforts for the ClearTrace system; (iii) commence clinical trials for the ablation catheter component of the ClearTrace system; and (iv) expand our research to apply our technologies to additional product applications.

Product development timelines, likelihood of success and total costs vary widely by product candidate. At this time, due to the risks inherent in the product clearance and approval process and given the early stage of development of our product candidates, we are unable to estimate with any certainty the costs that we will incur in the continued development of our product candidates for commercialization.

General and Administrative Expenses

Our general and administrative expenses consist primarily of: salaries, travel and benefits for administrative personnel; share-based compensation; professional fees, including fees for attorneys and outside accountants; selling costs; occupancy costs; insurance; and other general and administrative expenses, which include corporate licenses and taxes, postage, office supplies and meeting costs. Our general and administrative expenses are expected to increase due to costs associated with the commercialization of our ClearPoint system, increased headcount necessary to support our continued growth in operations, and the additional operational and regulatory burdens and costs associated with operating as a publicly traded company. In addition, we expect to incur additional costs associated with protecting our intellectual property rights as necessary to support our product offerings.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP. The preparation of these financial statements requires us to make estimates and

43

assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements as well as the reported expenses during the reporting periods. The accounting estimates that require our most significant, difficult and subjective judgments include revenue recognition, impairment of long-lived assets, computing the fair value of our derivative liability and the determination of share-based compensation. We evaluate our estimates and judgments on an ongoing basis. Actual results may differ materially from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in note 2 to our financial statements included elsewhere in this prospectus, we believe that the following accounting policies and estimates are most critical to a full understanding and evaluation of our reported financial results.

Revenue Recognition.    We evaluate revenue recognition on an agreement-by-agreement basis which, as of March 31, 2010, principally involved two license agreements with Boston Scientific. Both agreements provide various revenue streams for us, including an up-front licensing fee for one of the licenses, various milestone payments, payments for research and development and consulting services, and royalties.

We evaluate the various elements of these agreements based upon GAAP for multiple element arrangements to determine whether the various elements represent separate units of accounting. This evaluation requires subjective determinations about the fair value of each element and whether delivered elements have stand alone value and, therefore, are separable from the undelivered contract elements for revenue recognition purposes. In addition, we evaluated repayment provisions associated with one of the license agreements which, under certain conditions, would require us to return payments received under the agreement. In both license agreements, we concluded that all of the contract elements should be treated as a single unit of accounting. As such, all amounts received were initially recorded as deferred revenue and thereafter recognized as revenue over our estimated period of performance on a straight-line basis. In the case of the license with possible repayment obligation provisions, revenue recognition will not occur until the repayment obligation period expires.

Note 2 to our financial statements, “Significant Accounting Policies—Revenue Recognition”, more fully describes the deliverables under these license agreements including our rights, obligations and cash flows.

Inventory.    Inventory is carried at the lower of cost (first-in, first-out method) or net realizable value for products that are cleared or approved for commercial sale or for which clearance or approval is anticipated. As of March 31, 2010, all items included in inventory related to our ClearPoint system. At each reporting period in which our balance sheet reflects inventory related to product candidates that do not have regulatory clearance or approval, we evaluate the likelihood of receiving regulatory clearance or approval for these product candidates based on input from our external regulatory advisers. We also consider our anticipated selling prices based on analysis of product pricing of competitors and review of market information prepared by third party research analysts to determine net realizable value.

Valuation Allowance for Deferred Tax Assets and Liabilities.    Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that included the enactment date.

Valuation allowances are recorded for deferred tax assets when the recoverability of such assets is not deemed more likely than not.

We have evaluated the effect of the guidance provided by GAAP regarding accounting for uncertainty in income taxes that became effective in 2009. In that regard, we have evaluated all tax positions that could have a significant effect on the financial statements and determined we have no uncertain tax positions at March 31, 2010 that could have a significant effect on our financial statements. Our tax returns after 2005 remain open for examination.

Impairment of long-lived assets.    We evaluate the recoverability of our long-lived assets (finite lived intangible assets and property and equipment) whenever events or changes in circumstances indicate that the carrying amount of long-lived assets may not be fully recoverable. When this occurs, the expected undiscounted future cash flows are compared to the net book value of the related assets. If the net book value of the related assets exceeds the expected undiscounted future cash flows of the assets, the carrying amount will be reduced to the present value of the expected future cash flows and an impairment loss would be recognized.

Share-based compensation.    We account for compensation for all arrangements under which employees and others receive shares of stock or equity instruments (including options and warrants) in accordance with FASB ASC Topic 718 “Compensation – Stock Compensation”, or ASC Topic 718. Under ASC Topic 718, the fair value of each award is estimated and amortized as compensation expense over the requisite service period. The fair value of our share-based awards is estimated on the grant date using the Black-Scholes valuation model. This valuation model requires the input of highly subjective assumptions, including the expected price volatility and estimated option term. As we have been operating as a private company, we are unable to use actual price volatility and option life data as input assumptions within our Black-Scholes valuation model. Prior to October 2009, we used expected volatilities based on the historical volatility of the industry sector in which we operate, in accordance with the guidance set forth in ASC Topic 718.

Beginning in October 2009, we based our estimate of expected volatility on the average historical volatilities of publicly traded companies we deemed similar due to our lack of historical volatility data of our own. We will consistently apply this methodology until a sufficient amount of historical information regarding the volatility of our share price becomes available.

To estimate the expected term, we chose to utilize the “simplified” method for “plain vanilla” options as discussed in the Securities and Exchange Commission’s Staff Accounting Bulletin 107, or SAB 107. We believe that all factors listed in SAB 107 as pre-requisites for utilizing the simplified method are true for us and for our share-based payment arrangements. We intend to utilize the simplified method for the foreseeable future until more detailed information about exercise behavior becomes available.

Our risk-free interest rates are based on a zero-coupon U.S. treasury instrument, the term of which is consistent with the expected term of the stock options. We have not paid and do not anticipate paying cash dividends on our shares of common stock; therefore, the expected dividend yield is assumed to be zero. The fair value of share-based payments are generally amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods.

We believe there is a high degree of subjectivity involved when using option pricing models to estimate share-based compensation under ASC Topic 718. Currently, there is not a market-based mechanism or other practical application to verify the reliability and accuracy of the estimates stemming from these valuation models, nor is there a means to compare and adjust the estimates to actual values. Although the fair value of stock option awards is determined in accordance with ASC Topic 718 using an option pricing model, that value may not be indicative of the fair value observed in a market transaction between a willing buyer and a willing seller. If factors change and we employ different assumptions in the application of ASC Topic 718 in future periods than those currently applied under ASC Topic 718, the compensation expense we record in future periods under ASC Topic 718 may differ significantly from what we have historically reported.

Total share-based compensation expense for the three months ended March 31, 2010 and 2009 was approximately $54,000 and $38,000, respectively, and for years ended December 31, 2009 and 2008, it was approximately $131,000 and $118,000, respectively. As of March 31, 2010 there was approximately $343,000 of unrecognized compensation cost related to nonvested share-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of approximately three years.

Research and development costs.    Research and development costs consist of direct and indirect costs associated with the development of our technologies. These costs are expensed as incurred.

Derivative Financial Instruments.    We account for derivative instruments in accordance with FASB ASC Topic 815, which establishes accounting and reporting standards for derivative instruments and hedging activities, including certain derivative instruments embedded in other financial instruments or contracts and requires recognition of all derivatives on the balance sheet at fair value. We calculate the fair value of these instruments using the Black-Scholes valuation model. Changes in the fair value of derivatives are recorded each period as a gain or loss in the statement of operations unless the derivative qualifies for hedge accounting. At March 31, 2010 and at December 31, 2009 and 2008, we did not have any derivative instruments that were designated as hedges.
