About NuVasive

NuVasive is a medical device company focused on the design, development and marketing of products for the surgical treatment of spine disorders. The Company's product portfolio is focused on applications in the over $2.9 billion U.S. spine fusion market. The Company's current principal product offering includes a minimally disruptive surgical platform called Maximum Access Surgery, or MAS(TM), as well as classic fusion implants.

The MAS platform offers advantages for both patients and surgeons such as reduced surgery and hospitalization time and faster recovery. MAS combines three categories of current product offerings -- NeuroVision(R), a proprietary software-driven nerve avoidance system; MaXcess(R), a unique split-blade design retraction system; and specialized implants, like SpheRx(R) and CoRoent(R) -- that collectively minimize soft tissue disruption during spine surgery while allowing maximum visualization and surgical reproducibility. NuVasive's classic fusion portfolio is comprised predominantly of proprietary saline packaged bone allografts and internal fixation products. NuVasive also has a robust R&D pipeline emphasizing both MAS and motion preservation products such as Total Disc Replacement (TDR) and the NeoDisc(TM) investigational nucleus-like replacement device.
