1. A method of making a stimulation lead, the method comprising:

  • forming a rib framework comprising a plurality of pre-electrodes attached together in a single helix or a double helix, wherein the rib framework comprises at least one alignment tab;

    attaching a conductor to each of the pre-electrodes;

    disposing the rib framework into a mold with the at least one alignment tab of the rib framework disposed in a corresponding slot of the mold;

    forming a lead body between the pre-electrodes; and

    removing a portion of the lead body and the pre-electrodes to generate a plurality of separated segmented electrodes arranged in the single helix or the double helix, wherein each of the pre-electrodes has a greater thickness at a portion of the pre-electrode corresponding to the segmented electrode and a smaller thickness at the portion of the pre-electrode that is removed.
