SYSTEMS AND METHODS FOR MAKING AND USING ENHANCED ELECTRODES FOR ELECTRICAL STIMULATION SYSTEMS

摘要

A lead assembly for providing electrical stimulation of patient tissue includes at least one elongated lead body, each of the at least one lead bodies having a distal end and a proximal end. A plurality of electrodes are disposed at the distal end of the at least one lead body, each of the electrodes having an outer surface. A plurality of dimples are defined along the outer surface of at least one of the plurality of electrodes, the plurality of dimples configured and arranged to provide a larger surface area for the at least one dimpled electrode than that of a similarly-sized electrode with a flat outer surface. A plurality of terminal are disposed at the proximal end of the at least one lead body. A plurality of conductive wires couple each of the plurality of electrodes to at least one of the plurality of terminals.
