1. A method of forming a multi-electrode lead, the method including the steps of:

  • a. providing an elongated core having;

    (1) a length extending between a proximal end and a distal end, and(2) a nonconductive exterior surface;

    b. forming conductive tracks on the core'"'"'s exterior surface, wherein the step of forming the conductive tracks includes the steps of;

    i. forming a conductive layer about the core'"'"'s exterior surface, andii. removing portions of the conductive layer to define the conductive tracks,and wherein the tracks;

    (1) extending along the core'"'"'s exterior surface from locations nearer the core'"'"'s proximal end, and(2) terminating in electrodes at locations nearer the core'"'"'s distal end;

    c. forming a nonconductive outer layer covering;

    (1) the tracks, except for the electrodes thereon, and(2) the core'"'"'s exterior surface adjacent the tracks.
