Abstract
In one embodiment, a method for fabricating a neurostimulation stimulation lead comprises: providing a plurality of ring components and hypotubes in a mold; placing an annular frame with multiple lumens over distal ends of the plurality of hypotubes to position a portion of each hypotube within a respective lumen of the annular frame; molding the plurality of ring components and the hypotubes to form a stimulation tip component for the stimulation lead, wherein the molding fills interstitial spaces between the plurality of ring components and hypotubes with insulative material; and forming segmented electrodes from the ring components after performing the molding.
