NuVasive is a medical device company focused on developing minimally disruptive surgical products and procedures for the spine. The Company is the 5^th 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.
