BIOABSORBABLE SURGICAL DEVICE FOR TREATING NERVE DEFECTS

摘要

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, is described.
