A body implantable lead having a barrel-shaped ring electrode with the ends of the barrel embedded into the lead casing material. A cylindrical flange within the bore of the ring electrode contacts the lead conductor. The lead and electrode are formed by placing the lead in a press with the electrode between a pair of collets with elliptical working surfaces and the lead casing and conductor passing through the axial bore of the collets, and forcing the collets together to shape the electrode and to force the ends of the ring into the casing and the flange into contact with the lead conductor. |
