Abstract: A surgical lead which provides electrical stimulation to nerve tissue comprising two percutaneous lead bodies 12, 14 bonded together. The inventive lead body 10 results in the equivalent of a surgical lead body with columns of electrodes either adjacent to or offset from each other. A bridge 20 of urethane material is used to bond together the percutaneous lead bodies and still provide suitable flexibility of the lead. The surface of the electrodes may be coated, in part, with a suitable non-conductive coating 18 to effectively direct the electrical stimulation signals toward the targeted stimulation area. Significantly, the resulting lead is sized to fit within a needle having a similar cross-section, thereby permitting the percutaneous implantation of the inventive lead

Abstract: A needle for introduction of a paddle style lead 55 near a spinal column or other nervous system structures, central or peripheral, of a patient includes a body having a proximal end and a distal end, and a lumen 25 with a continuous oblong cross section. The distal end of the body has an introducer portion 35 where the top side of the introducer has an orifice to allow for protrusion of the paddle style lead from the lumen into the spinal column area or into or near other nervous system structures. The needle has a hub 40 affixed to the proximal end of the body which is adapted to receive a stylet 45. The needle may also have a stylet that is inserted within the lumen. The introducer of the needle has a curvature extending from the bottom side toward the top side at the distal end and guides the introduction of the paddle style lead near the spinal column or other nervous system structures.
