Three lead universal pacing and shocking system
First Claim
1. An implantable cardiac stimulation system for delivering stimulation pulses to any one chamber or combination of chambers of a heart, the system comprising:
- a lead system consisting of a first lead for implant in the right ventricle and having a right ventricular defibrillation electrode, a second lead for implant in the coronary sinus and having a left ventricular defibrillation electrode for placement in electrical contact with the left ventricle adjacent to the left ventricle and within the coronary sinus and a first left ventricular pacing electrode for placement in electrical contact with the left ventricle and within the coronary sinus and a second left ventricular pacing electrode proximal to the first left ventricular pacing electrode for placement in electrical contact with the left ventricle, and a third lead for implant in the coronary sinus and having a left atrial defibrillation electrode for placement in electrical contact with the left atrium adjacent to the left atrium and within the coronary sinus, one of the leads further including a right atrial defibrillation electrode for placement in one of the right atrium and superior vena cava; and
an implantable cardiac stimulation device including a programmable pulse generator that delivers defibrillation pulses to the defibrillation electrodes.

Abstract
A three lead implantable cardiac stimulation system is capable of delivering stimulation pulses to any one chamber or combination of chambers of a heart. The system includes a first lead for implant in the right ventricle and having a right ventricular defibrillation electrode, a second lead for implant in the coronary sinus and having a left ventricular defibrillation electrode, and a third lead for implant in the coronary sinus and having a left atrial defibrillation electrode. One of the leads further including a right atrial defibrillation electrode for placement in one of the right atrium and superior vena cava. The system further includes an implantable cardiac stimulation device including a programmable pulse generator that delivers defibrillation pulses to any one of the defibrillation electrodes or to any combination of the defibrillation electrodes. The leads may further provide at least one pacing electrode for each chamber of the heart and the device is programmable to provide pacing pulses to any one of the pacing electrodes.
