1. A device for brain stimulation, comprising:
- a lead having a longitudinal surface, a proximal end and a distal end; and
a plurality of electrodes disposed along the longitudinal surface of the lead near the distal end of the lead, the plurality of electrodes comprising at least four segmented electrodes having exposed surfaces, each exposed surface having a center point;
wherein the at least four segmented electrodes are configured and arranged so that each of the center points are disposed at different longitudinal positions and at different radial positions about the longitudinal surface of the distal end of the lead.

Abstract
A device for brain stimulation includes a lead having a longitudinal surface, a proximal end and a distal end; and a plurality of electrodes disposed along the longitudinal surface of the lead near the distal end of the lead. The plurality of electrodes includes at least four segmented electrodes having exposed surfaces where each exposed surface has a center point. The center points of the at least four segmented electrodes are disposed on a substantially helical path about the longitudinal surface of the lead.
