1. A method of delivering a cardiac harness assembly to the heart, comprising:
- a. providing a cardiac harness assembly having a highly elastic metallic cardiac harness and at least one electrode;
b. electrically insulating the metallic cardiac harness from the at least one electrode;
c. providing a delivery device for carrying the cardiac harness assembly;
d. providing a minimally invasive access site;
e. inserting the delivery device through the minimally invasive access site; and
f. delivering the cardiac harness assembly to the heart.

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.
