Systems and methods for making and using enhanced electrodes for electrical stimulation systems
First Claim
1. A medical lead for providing electrical stimulation of patient tissue, the medical lead comprising:
- a lead body having a distal end portion, a proximal end portion, a circumference, and a longitudinal length;
a plurality of electrodes disposed along the distal end portion of the lead body, each of the plurality of electrodes having a width, a length, and an outer surface, wherein at least one of the plurality of electrodes is a segmented electrode that extends around less than the entire circumference of the lead body and that is also a grooved electrode that defines a plurality of grooves along the outer surface;
a plurality of terminals disposed along the proximal end portion of the lead body; and
a plurality of conductive wires coupling the plurality of terminals to the plurality of electrodes.

Abstract
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.
