Claim:
1. A sterile device for protecting against a neuroma forming at a stump of a transected nerve, wherein the device comprises: a body having an open proximal end and, integrally formed with the body, a closed distal end wherein the body of the device is less than 100 mm in diameter and less than 500 mm in length; wherein the body, including the closed distal end, defines an internal chamber, without openings other than at the proximal end, thereby inhibiting axonal escape from the device when the device is implanted on the nerve stump by inserting the nerve stump through the opening in the proximal end; and one or more separators within the internal chamber that divide the internal chamber thereby creating a plurality of separate volumes into which regenerating axons grow such that one or more regenerating axons are physically separated from one or more other regenerating axons; and wherein the device comprises a biomaterial that remodels into a tissue cushion after implantation.
