Patent Images
1. A method for delivering an electrode to a heart of a patient, comprising:
- providing at least one electrode for defibrillation and/or pacing and sensing;
the at least one electrode having a first surface facing an epicardial surface of the heart and a second surface facing away from the epicardial surface of the heart, the second surface being coated with a dielectric material;
forming a minimally invasive access site in a patient;
forming a small incision in a pericardium of the heart;
inserting the at least one electrode through the minimally invasive access site and through the small incision in the pericardium; and
positioning the at least one electrode on or near the epicardial surface of 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.
