Abstract
A stimulation lead includes a lead body having a longitudinal surface, a distal end, a proximal end, and a shaft extending along at least a portion of the distal end of the lead body. The stimulation lead also includes multiple segmented electrode members disposed on the shaft along the longitudinal surface of the lead body near the distal end of the lead body. Each segmented electrode member includes a ring structure which forms at least a partial ring and is disposed on the shaft, and a segmented electrode coupled to the ring and having an exposed surface configured and arranged for stimulating tissue when the stimulation lead is implanted.
