ABSTRACT:
A defibrillation lead provided with an elongated defibrillation electrode and a bipolar electrode pair for cardiac pacing and sensing. The cardiac pacing and sensing electrodes comprise an extendable helical electrode and a ring or ring tip electrode located on or adjacent the distal end of the lead body. Inter-electrode separation for pacing and sensing is provided by means of insulation applied to the helical electrode, leaving only the tip portion exposed. The overall configuration of the lead allows the defibrillation electrode to be located very close to the distal end of the lead body, while preserving the ability to employ a bipolar electrode pair for cardiac pacing and sensing.
