ABSTRACT:
A medical electrical lead to conduct electrical stimulation and/or signals between an electrical stimulator and a heart site includes an elongated lead body extending to a proximal connector for attachment to the electrical stimulator. An electrode head at the distal end includes an electrode tip member for fixation to the heart and an electrode backing member fixed to the lead body is releasably attachable to the electrode tip member for transmission of electrical signals between the heart and the electrical stimulator. The electrode tip member may include a first non-conductive base with an outwardly projecting tip electrode and a first mounting member projecting oppositely away from the non-conductive base. The electrode backing member includes a second non-conductive base and a second mounting member thereon adapted for mounting engagement with the first mounting member for selectively releasably but firmly integrating the electrode tip member and the electrode backing member.
