1. A method of fabrication of a stimulation lead comprising a plurality of segmented electrodes for stimulation of tissue of a patient, the method comprising:

  • providing a substrate comprising (i) a substantially cylindrical body and (ii) a plurality of projections extending radially from the cylindrical body;

    coating the substrate with first conductive material;

    patterning the first conductive material on the cylindrical body into a plurality of traces, the plurality of traces extending along the cylindrical body and electrically contacting conductive material about the plurality of projections;

    providing an insulative layer over the traces;

    coating the insulative layer over the traces with second conductive material;

    patterning the second conductive material to form at least a plurality of electrode surfaces including a plurality of segmented electrodes, the segmented electrodes being in electrical contact with conductive material on projections of the plurality of projections; and

    electrically coupling the plurality of traces to conductive wires of a lead body.
