    摘要: The present invention is directed to prostheses and methods for promoting nerve regeneration. The proximal and distal ends of a severed nerve are brought into close proximity and are enclosed by a tubular prosthesis. In one preferred embodiment, a monosuture is used to hold the nerve ends in close proximity. A tight seal is formed between the prosthesis and the injured nerve so as to isolate the injured nerve within the prosthesis from the rest of the body of the host. Additionally, in one preferred embodiment, nerve grafts may be incorporated into the prosthesis and nerve regeneration promoting substances may be incorporated within the nerve graft to further enhance nerve regeneration. Prostheses and methods for inhibiting the formation of neuromas are also disclosed.

    摘要: The present invention is directed to prosthesis and methods for promoting nerve regeneration. The proximal and distal ends of a severed nerve are brought into close proximity and are enclosed by a tubular prosthesis. In one preferred embodiment, a epineurial or endoneurial monosuture is used to hold the nerve ends in close proximity. A tight seal is formed between the prosthesis and the injured nerve so as to isolate the injured nerve within the prosthesis from the rest of the body of the host. Additionally, in one preferred embodiment, nerve grafts may be incorporated into the prosthesis and nerve regeneration promoting substances may be incorporated within the nerve graft to further enhance nerve regeneration. In another preferred embodiment, a prosthesis is coated with a material which is slippery with relation to the surrounding body tissue and the prosthesis is formed of or coated with a material around the inside of the prosthesis which will substantially adhere to the severed nerve ends so as to prevent substantial movement of the severed nerve ends within the prosthesis. In yet another preferred embodiment, such an outside coating around the prosthesis terminates in two longitudinal flaps which serve to form a fluid-tight seal along the tubular prosthesis. In still another preferred embodiment, the ends of the prosthesis overlap and are formed so as to bias against each other in a spiral tube configuration, thereby providing for firm closure of the prosthesis around a variety of sizes of injured nerves. Also disclosed are various devices and methods for inhibiting the formation of neuromas, such as an open-ended tube or a neuroma-inhibition device formed as a cap member having a reservoir formed therein.
