Patent ID: 7191017

Claim:
A two-part cardiac lead for use with a cardiac function management device, the lead comprising: an elongated, flexible outer lead portion including a lead body extending from a proximal end to a distal end and defining an internal longitudinal lumen, a conductive coil extending substantially from the proximal end to the distal end, a surface electrode coupled to the lead body near the distal end, a conductive terminal connector defining an internal bore and adapted to couple with the cardiac function management device, the conductive terminal connector coupled to the proximal end of the lead body, and a sleeve located in the internal bore and having an indentation; and an inner lead portion including a longitudinally-extending conductive member sized to fit within the internal longitudinal lumen and a pin having a protrusion sized to mechanically couple with the sleeve indentation, the pin adapted to electrically couple with the longitudinally-extending conductive member; wherein the sleeve is adapted to electrically isolate the pin from the conductive terminal connector.
