Abstract
A modified nerve cuff electrode is designed to enhance the stability of neural recording and/or nerve stimulation. Any nerve cuff electrode includes a nerve cuff and a plurality of electrodes within the nerve cuff. While traditional nerve cuff electrodes have every one of the plurality of electrode contacts on the inner surface of the nerve cuff, in the modified nerve cuff electrode each of an inner surface and an outer surface of the nerve cuff has at least one electrode contact. The at least one electrode contact on the outer surface can be electrically isolated from the peripheral nerve to provide a stable reference or ground during recording or a stable pathway for a return current during stimulation to enhance the stability of the recording or the stimulation.
