Abstract
An endocardial lead which includes an elongated, flexible, insulative tubing, a central flexible conductor positioned within the tubing and having one end adapted to be electrically connected to a pulse generator. A ribbon-shaped bonding member is connected to the other end of the central conductor. The ribbon-shaped bonding member extends through an aperture in the wall of the insulative tubing and is positioned along the outer surface of the tubing. A ribbon-shaped electrode is helically wound around the outer surface of the insulative tubing and positioned over the ribbon-shaped bonding member. With this configuration, a low impedance electrical connection is provided between the ribbon-shaped electrode and the central conductor, and between adjacent turns of the electrode.
