Abstract

A cardiac harness for treating or preventing congestive heart failure is configured to be placed about at least a portion of a patient's heart (30) so as to apply a mild compressive force on the heart. In one embodiment, the cardiac harness (130) comprises a plurality of spaced apart conductive panels (136) arranged so that there is no electrical continuity circumferentially around the harness (130). In an additional embodiment, a cardiac harness (220) is insulated so as not to conduct electricity about the harness (220).
