1. A method for fabricating a neurostimulation stimulation lead comprising:
providing a plurality of ring components and hypotubes in a mold;
molding the plurality of ring components and the hypotubes to form a stimulation tip component for the stimulation lead; and
forming segmented electrodes from the ring components after performing the molding,
wherein the plurality of hypotubes comprise different lengths for the corresponding hypotubes such that multiple ones of the plurality of hypotubes extend different lengths after the molding is performed to facilitate subsequent connection of the hypotubes to conductor wires of a lead body in a correct order.
