Abstract
A device for brain stimulation includes a lead having a longitudinal surface, a proximal end, a distal end and a lead body. The device also includes a plurality of electrodes disposed along the longitudinal surface of the lead near the distal end of the lead. The plurality of electrodes includes a first set of segmented electrodes comprising at least two segmented electrodes disposed around a circumference of the lend at a first longitudinal position along the lead; and a second set of segmented electrodes comprising at least two segmented electrodes disposed around a circumference of the lead at a second longitudinal position along the lead. The device further includes one or more conductors that electrically couple together all of the segmented electrodes of the first set of segmented electrodes.
