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 so
as to apply a mild compressive force on the heart. In one embodiment, the
cardiac harness comprises a plurality of spaced apart conductive panels
arranged so that there is no electrical continuity circumferentially
around the harness. In an additional embodiment, a cardiac harness is
provided that is insulated so as not to conduct electricity
circumferentially about the harness.
