Abstract
A stimulation lead includes a lead body having a longitudinal length, a distal portion, and a proximal portion; terminals disposed along the proximal portion of the lead body; an electrode carrier coupled to, or disposed along, the distal portion of the lead body; segmented electrodes disposed along the electrode carrier; and conductors extending along the lead body and coupling the segmented electrodes to the terminals. The electrode carrier includes a lattice region defining segmented electrode receiving openings. Each of the segmented electrodes extends around no more than 75% of a circumference of the lead and is disposed in a different one of the segmented electrode receiving openings of the electrode carrier.
