    摘要: First and second electrical wires (10), (12) are wrapped helically around a polyprolene core (22). Along a single helical portion (A), a sheath (24) is placed over the spiral wound wires and core. In an open double helix portion (B), the core with spiral wound wires is wrapped into an open helix. At an electrical stimulation portion (C), insulation is removed from the wires such that bare conductors (14), (16) are wrapped spirally around the core. The core with the spiral wrapped conductors is wrapped in an open helix. A plurality of barbs (32) are mechanically connected along the entire length of the exposed electrical conductor surface. The core extends beyond the end of the electrical conductor surface to facilitate insertion into a selected site with a cannula (64).
