Abstract
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.
