1. An apparatus for treating a heart, comprising:
- a medical device formed from a metallic alloy and configured to at least partially surround the heart;
a plurality of electrodes attached to the medical device and having a predetermined spacing;
the medical device being coated with a dielectric material to electrically insulate the medical device from the electrodes; and
the medical device and electrodes being compressible to a first delivery configuration small enough to be inserted through an incision in a pericardium, and a second expanded configuration wherein the medical device at least partially surrounds 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.
