Patent ID: 8732944

Claim:
A method of fabricating stimulation leads, the method comprising: providing a spool of polymer film; providing a plurality of payout carriers of wire; drawing the polymer film from the spool and the wires from the plurality of payout carriers over a rotating drum, wherein the drum comprises a plurality of grooves over an outer circumferential surface of the drum for directing the wires from the plurality of payout carriers, wherein a distance of each groove from an edge of the drum is varied about the circumference of the drum; bonding the wires to the polymer film while performing the drawing to form an intermediate assembly comprising the polymer film as a carrier with the bonded wires in a repeating pattern along a length of the intermediate assembly; forming respective segments from the intermediate assembly; forming respective stimulation portions from the respective segments, the stimulation portions comprising electrodes electrically coupled to the wires of the segments of the intermediate assembly; and forming stimulation leads including the stimulation portions with the wires of the segments electrically coupled to wires of respective lead bodies.
