Acquisition of Impulse Monitoring Inc. by NuVasive, Inc.

Columbia, MD – October 7, 2011 – Impulse Monitoring, Inc. (IMI) today announced that the agreement to be acquired by NuVasive, Inc. (Nasdaq: “NUVA”), had closed. Going forward, IMI will continue to exclusively provide neuromonitoring services as an independent subsidiary of a larger organization. There will be no change to the nature and delivery of its services, or to the Company's operations and management. The expertise of IMI's personnel, its infrastructure and its management team are essential to achieving these NuVasive's long-term growth objectives.

In acquiring IMI, a proven, industry-leading IONM provider, NuVasive will add depth to a growing surgical procedure platform that will enable surgeons and hospitals to address all of their neuromonitoring needs.

In becoming a part of NuVasive, IMI will now be better positioned to more aggressively expand its service “footprint” into other areas of the country, and enjoy the support and the resources of a larger organization.

About NuVasive

NuVasive is a medical device company focused on developing minimally disruptive surgical products and procedures for the spine. The Company is the 5th largest player in the $7.7 billion global spine market.

NuVasive's principal product offering is based on its Maximum Access Surgery, or MAS® platform. The MAS platform combines four categories of products that collectively minimize soft tissue disruption during spine surgery with maximum visualization and safe, easy reproducibility for the surgeon: a proprietary software-driven nerve avoidance system; MaXcess®, a unique split-blade retractor system; a wide variety of specialized implants; and several biologic fusion enhancers. MAS significantly reduces surgery time and returns patients to activities of daily living much faster than conventional approaches. Having redefined spine surgery with the MAS platform's lateral approach, known as eXtreme Lateral Interbody Fusion, or XLIF®, NuVasive has built an entire spine franchise. With over 65 products today spanning lumbar, thoracic and cervical applications, the Company will continue to expand and evolve its offering predicated on its R&D focus and dedication to outstanding service levels supported by a culture of Absolute Responsiveness®.
