Patent ID: 7783366

Claim:
A medical electrical lead adapted to conduct electrical signals from an implantable or external electrical stimulator to a site of the heart and to conduct electrical signals of the heart from the site to the implantable or external electrical stimulator comprising: an elongated lead body extending from a lead body distal end to a connector at the lead body proximal end for mechanical and electrical attachment to the electrical stimulator; an electrically non-conductive disk member at the lead body distal end; at least a first electrode fixed on the disk member and protruding therefrom for puncturing engagement with the epicardial surface of the heart in the region of an atrioventricular node (AVN) fat pad; at least a second electrode fixed on the disk member, spaced from the first electrode, and protruding therefrom for puncturing engagement with the epicardial surface of the heart in the region of the AVN fat pad; a first conductor extending from the first electrode to a first terminal of the connector; and a second conductor extending from the second electrode to a second terminal of the connector wherein the connector at the proximal end includes a cathode pin and an anode ring; wherein the first conductor extends between the first electrode and the cathode pin; and wherein the second conductor extends between the second electrode and the anode ring.
