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.
