1. An elongate flexible, electrically conductive neural stimulator lead including an electrical conductor for implantation in the spinal column of a patient and having leading and trailing ends, a non-conductive coating covering said conductor, and an electrode electrically connected to the conductor at one end thereof with at least a portion of said electrode being in electrical communication with the exterior of said coating to define an electrical contact region, wherein the improvement in said lead comprises:

  • said leading and trailing ends each being of substantially uniform diameter;

    said contact region being located substantially intermediate said leading and trailing ends of said lead such that each of said leading and trailing ends is sufficiently long as to percutaneously exit the body at spaced locations therein when said contact region is positioned within the spinal column of a patient during implantation; and

    means adjacent said contact region for stabilizing said lead within the spinal column with the contact region within the spinal column and the leading and trailing ends percutaneously exiting the body.
