ABSTRACT:
A system or appliance to treat heart failure (HF) conditions. The appliance includes a structural support or cardiac constraint to limit further distension of weakened heart tissue. The appliance also includes an implantable stimulation pulse generator and controller such that the appliance can automatically monitor cardiac activity and provide therapeutic stimulations for detected arrhythmias. The appliance can also include one or more surface electrodes. The surface electrodes can be arranged on opposite sides of the heart to apply relatively spatially uniform stimulation potentials across the heart with reduced shunting around the target tissue. A surface electrode can also be arranged to wrap substantially about a periphery of the patient's heart and used with an internal electrode to apply a relatively homogeneous shock while facilitating lower voltage and smaller shocking capacitors.
