Abstract
A pace/sense electrode is associated with a cardiac harness for treating the heart. The pace/sense electrode is positioned on the epicardial surface of the heart, preferably under the cardiac harness, to provide pacing and sensing therapy to the heart. Compressive forces from the cardiac harness serve to hold the pace/sense electrode in place and to push the electrode into direct contact with the epicardial surface of the heart. Various means are provided for placing the pace/sense electrode under the cardiac harness in a minimally invasive procedure.

17. A method for pacing/sensing a beating heart, comprising:
-
inserting the cardiac harness through a minimally invasive access site and around at least a portion of the heart; and
inserting a moveable structure having a body retaining an electrode through the minimally invasive access site and positioning the moveable structure between the cardiac harness and the epicardium of the heart, wherein compressive forces of the cardiac harness hold the moveable structure in position on the heart. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
