ABSTRACT:
A medical device is disclosed for use in regenerating a severed nerve. The device includes an implantable, tubular, electrically-charged membrane having openings adapted to receive the ends of the severed nerve and a lumen having a diameter ranging from about 0.5 millimeters to about 2.0 centimeters to permit regeneration of the nerve therethrough. The membrane is fabricated such that an electric charge is exhibited at the inner membrane surface to stimulate regeneration by axonal sprouting and process extension. Also disclosed are methods for repairing a severed nerve and for preparing a medical device for use in regeneration of a severed nerve.
