Abstract
One embodiment is a stimulation lead including a lead body comprising a longitudinal surface, a distal end, and a proximal end; and multiple electrodes disposed along the longitudinal surface of the lead body near the distal end of the lead body. The multiple electrodes include multiple segmented electrodes with each of the segmented electrodes having an exterior surface, an interior surface opposite the exterior surface, a proximal end, and a distal end. At least one of the segmented electrodes includes one or more of a) at least one channel formed in the segmented electrode and extending from the proximal end to the distal end of the segmented electrode, b) an arcuate groove formed in at least one of the distal end surface or the proximal end surface, or c) a notch formed in the segmented electrode and extending from the proximal end to the distal end of the segmented electrode.
