Patent ID: 8533944

Claim:
A method of fabricating a stimulation lead for stimulation of tissue of a patient, the method comprising: providing a plurality of cables, wherein each of the cables comprises a plurality of wires twisted about a core support and disposed within an outer sheath, wherein each of the plurality of wires comprises a coating of insulative material to electrically isolate each wire from each other wire within the respective cable, each of the plurality of wires being disposed in a single layer circumferentially about a central axis of the respective cable; wrapping the plurality of cables about a central core in a helical manner to form a cable assembly, wherein during the wrapping each cable of the plurality of cables is rotated so that each wire of a respective cable is disposed at an exterior surface of the cable assembly at respective axial positions of the cable assembly; providing an outer insulative layer over the cable assembly; forming a lead body assembly from the cable assembly; and fabricating a plurality of electrodes and terminals that are electrically coupled to the plurality of wires of the plurality of cables of the lead body assembly to form the stimulation lead.
