Abstract
A method of forming material including alternating layers of fibrin and collagen, formed into tubes, is disclosed for use in repairing transected nerve fibers either by tubulization of the approximated nerve ends, or as an artificial graft which are placed in the severed ends of the nerve, for promotion of nerve growth and regeneration. The new material is treated to reduce antigenicity and is resorbed into the body following regeneration of the nerve fibers.
