Abstract
A threaded pacing electrode assembly for use in implantable electrical leads. The electrode is provided with an exposed portion adapted to make electrical contact with body tissue and with a cylindrical portion proximal to the exposed portion provided with a helical screw thread. A conductor coil which has an inner diameter smaller than the outer diameter of the cylindrical portion is mounted to the exterior of the cylindrical portion, coiled within the screw thread. A transparent insulating sleeve covers the cylindrical portion, is frictionally retained by the thread, and assists in maintaining the conductor coils in contact with the cylindrical portion.
