ABSTRACT:
A cardiac lead having ring electrodes positioned at predetermined locations along the length of the lead either for stimulating the heart at various selected locations. The cardiac lead includes an insulative tubing having a plurality of apertures positioned at the distal end of the lead at selected locations along the length of the tubing. A plurality of coiled conductors are positioned within the tubing and each extend through a respective one of the apertures. The insulation is removed from the end of the conductor for that portion of the conductor extending outside of the insulative tubing, and this uninsulated portion of the conductor is coiled about the peripheral surface of the insulative tubing. A plurality of ring electrodes are each positioned to cover a respective one of the coils of uninsulated conductor.
