Abstract
A system for treating the heart includes a cardiac harness associated with a cardiac rhythm management devise which includes at least electrodes and a power source. The cardiac harness applies a compressive force on the heart during diastole and systole. The electrodes will deliver an electrical shock to the heart for defibrillation and/or can be used for pacing/sensing. The cardiac harness and electrodes are delivered and implanted on the heart by minimally invasive access.

65. A cardiac rhythm management device, comprising:
-
a cardiac harness formed from a nitinol alloy and mounted on the epicardial surface of the heart;
pacing/sensing electrodes attached to the cardiac harness so that the electrodes are in direct, non-penetrating contact with the epicardial surface of the heart;
the pacing/sensing electrodes having a surface area in the range from about 2 mm2 to about 12 mm 2m; and
leads extending from the electrodes to a pulse generator. - View Dependent Claims (66, 67, 68, 69)
