Abstract:
1. A lead assembly for providing electrical stimulation of patient tissue, the lead assembly comprising: 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 disposed at the distal end of the at least one lead body, each of the electrodes having an outer surface, wherein 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, wherein an entire non-dimpled portion of the outer surface of the at least one dimpled electrode is flat; a plurality of terminal disposed at the proximal end of the at least one lead body; and a plurality of conductive wires coupling each of the plurality of electrodes to at least one of the plurality of terminals.
