Patent ID: 8224463

Claim:
A pacing lead for implantation in a coronary sinus having an opening and a wall defining an interior and presenting a diameter dimension, the pacing lead comprising: an elongated lead body defining an elongated longitudinal axis; and a preformed resilient fixation element extending from a distal end of the lead body and defining a loop structure laterally adjacent the lead body, wherein the loop structure terminates at a free lead tip having a lead tip axis and is configured to position the lead tip laterally adjacent to the lead body such that the lead tip axis intersects the elongated longitudinal axis of the elongated lead body wherein the lead tip points towards the elongated longitudinal axis of the elongated lead body, the pacing lead further including at least one electrode on either the lead body or the fixation element, the loop structure presenting a predetermined width dimension greater than the diameter dimension of the coronary sinus, wherein the loop structure is configured to be laterally compressed by the wall of the coronary sinus to bias the free lead tip against the wall of the coronary sinus laterally adjacent to the lead body and to bias the at least one electrode against the wall of the coronary sinus.
