Abstract: The regeneration of injured nerves is enhanced by supplying collagenase to the zone of injury of the nerve. Growth of nerve sprouts over the zone of injury is aided by the presence of effective amounts of collagenase during the regeneration process. If the nerve has been severed, collagenase is supplied to the ends of the proximal and distal stumps. A nerve graft may be interposed between the stumps. Natural fibrin has been used as glue to join nerve stumps, and collagenase is effective when used in admixture with fibrin.
Abstract: An automatic interconnection assembly with: on one side, a first connector element, and on the opposite side, a telescopic assembly having at its free end a second connector element. This assembly is moved by a control actuator, the extension of which makes the second connector element approach and then plug into the first connector element. Means axially and transversally align the two connector elements and orients them angularly with respect to each other, prior to the plug-in operation, as they approach each other.
