1. An electrical stimulation lead comprising:

  • an elongated lead body having a distal end portion, a proximal end portion, a longitudinal length, and a circumference, the lead body configured and arranged for insertion into a patient;

    a plurality of terminals disposed along the proximal end portion of the lead body;

    a plurality of conductors coupled to the plurality of terminals and extending along the longitudinal length of the lead body to the distal end portion of the lead body, the plurality of conductors comprising a first conductor and a second conductor;

    a plurality of electrodes disposed along the distal end portion of the lead body and coupled to the plurality of conductors, the plurality of electrodes comprisinga first set of segmented electrodes comprising a first segmented electrode and a second segmented electrode spaced apart from one another around the circumference of the lead body, wherein the first conductor is coupled to the first segmented electrode, anda second set of segmented electrodes comprising a third segmented electrode and a fourth segmented electrode spaced apart from one another around the circumference of the lead body, wherein the second conductor is coupled to the third segmented electrode,wherein the first set of segmented electrodes is disposed proximal to the second set of segmented electrodes along the longitudinal length of the lead body,wherein the first segmented electrode and the third segmented electrode are circumferentially-aligned with one another along the longitudinal length of the lead body;

    a first tab disposed on the first segmented electrode, the first tab extending inwardly from the first segmented electrode into the lead body, the first tab comprising an aperture through the first tab and surrounded by the first tab and sized to receive only a single one of the conductors; and

    a second tab disposed on the third segmented electrode, the second tab extending inwardly from the third segmented electrode into the lead body, the second tab comprising an aperture through the second tab and surrounded by the second tab sized to receive only a single one of the conductors;

    wherein the second conductor is physically received within the apertures of both the first and second tabs.
