ABSTRACT:
A device and a method for anatomic implantation to provide electrical interface to nerves. Included in the device are a pair of electrical leads secured to a coupling formed from a piece of woven sheet material, and having ends connected to spaced apart input terminals disposed adjacent to an inner surface of the coupling. Connected to the opposite ends of the leads are output terminals for interfacing to electrical recording or measuring instruments. During implantation, a subject nerve is embraced by the inner surface of the sheet material which is shaped for juxtaposition the outer surface of the nerve at a minimum spacing therefrom of 0.3 millimeters. In the period following implantation the interstices of the sheet material coupling receive anatomic tissue growth establishing a structurally stable dimensional relationship between the nerve and both the input electrodes and the coupling. The fixed input electrode spacing between the electrode and the nerve improves the quality of the electrical signals received from the nerve while the 0.3 millimeter minimum spacing insures that the nerve will continue living for extended periods of time.
