Bioabsorbable surgical device for treating nerve defects
First Claim
1. A medical device adaptable for use in the treatment of a nerve gap or defect comprising a flexible, porous tube of a bioabsorbable polymer material, said tube having a plurality of corrugations on its exterior surface positioned so as to allow said tube to be bent without crimping the internal surface of said tube and having a plurality of flats provided on its interior surface to provide a relatively smooth interior surface and having a substantially constant internal diameter to promote longitudinal axon growth within the tube device and across the nerve gap, and being capable of enclosing and protecting the ends of a severed or lacerated nerve.

Abstract
A bioabsorbable tube device for the repair of nerve defects or gaps comprising a flexible, porous, knitted or woven mesh tube. The tube device is crimped along its exterior to provide a tube which can be bent without pinching or crimping the internal circumference of the tube. The internal tube surface is relatively smooth to provide an optimum environment for longitudinal nerve axon growth within the tube.
