A surgically implantable electrode system has been conceived which includes two or more electrical elements embedded in a helically wound substrate made of insulative material. The contact elements are connected to electrical lead-in conductors which are encased in the substrate and extend from a common end of the substrate to a contact element. The substrate is wound around a nerve or nerve bundle in helical fashion until the contact elements are positioned against the nerve or nerve bundle surface at the desired location. A membrane is wrapped around the substrate to insulate the electrode system, and the lead-in conductors are anchored to relieve strain on the electrode system.

A surgically implantable electrode system for providing electrical connection to a nerve bundle, said system comprising: (a) electrode means having a helically-shaped carrier member of insulative material adapted to be positioned around said nerve bundle, said electrode means having at least two contact elements on said carrier member for engagement with said nerve bundle and an electrical lead-in conductor member connected to each of said contact elements, and (b) membrane means for enclosing said electrode means to confine electrical currents passing through said electrode means to said nerve bundle.
