Abstract
A stimulation lead includes an electrode carrier disposed along a distal portion of a lead body. The electrode carrier defines multiple segmented-electrode-receiving apertures extending between an outer surface and a central lumen. Each of the segmented-electrode-receiving apertures includes a ledge disposed around a perimeter of that segmented-electrode-receiving aperture and inset from the outer surface of the electrode carrier. The stimulation lead also includes multiple segmented electrodes, with each of the segmented electrode disposed in a different one of the segmented-electrode-receiving apertures with an outer stimulation surface exposed through the segmented-electrode-receiving aperture and an inner surface abutting the ledge disposed around the perimeter of that segmented-electrode-receiving aperture. Conductive wires extend along the lead body and couple the segmented electrodes to terminals.
