Coronary sinus lead with atrial sensing capability
First Claim
1. An apparatus for pacing, cardioverting or defibrillating a heart comprising:
- an implantable pulse generator;
a coronary sinus lead connected at a proximal end to said pulse generator comprising a lead body including at least two conductors encased within an insulation material, said coronary sinus lead having a coronary sinus defibrillating electrode at its distal end, the coronary sinus defibrillating electrode including an electrically conductive coil wrapped about an electrically conductive sleeve, at least one of said conductors of said lead body extending into said electrically conductive sleeve and electrically connected thereto; and
sensor means for sensing physical or electrical parameters in the atrial cavity, said sensor means attached to said coronary sinus lead.

Abstract
A coronary sinus lead, for use in combination with an implanted pulse generator which may be a pacemaker or defibrillator or combination thereof. The coronary sinus lead can deliver an electrical charge to pace, cardiovert or defibrillate the heart, and can sense cardiac activity in the coronary sinus of the heart. The coronary sinus lead may include additional sensor electrodes capable of sensing electrical or physical activity in the atrial cavity. The coronary sinus lead allows cardioversion and/or defibrillation stimuli to be provided by a large surface area electrode Which is passively implanted in the coronary sinus, to allow the pulse generator to provide appropriately synchronized atrial-ventricular pacing, cardioversion or defibrillation.
