In further keeping with the invention, the cardiac harness 20 includes a pair of leads 31 having conductive electrode portions 32 that are spaced apart and which separate panels 21. As shown in FIG. 5, the electrodes are formed of a conductive coil wire 33 that is wrapped around a non-conductive member 34, preferably in a helical manner. A conductive wire 35 is attached to the coil wire and to a power source 36. As used herein, the power source 36 can include any of the following, depending upon the particular application of the electrode: a pulse generator; an implantable cardioverter/defibrillator; a pacemaker; and an implantable cardioverter/defibrillator coupled with a pacemaker. In the embodiment shown in FIG. 5, the electrodes are configured to deliver an electrical shock, via the conductive wire and the power source, to the epicardial surface of the heart so that the electrical shock passes through the myocardium. Even though the electrodes are spaced so that they would be about 180° apart around the circumference of the heart in the embodiment shown, they are not so limited. In other words, the electrodes can be spaced so that they are about 450 apart, 60° apart, 90° apart, 120° apart, or any arbitrary arc length spacing, or, for that matter, essentially any arc length apart around the circumference of the heart in order to deliver an appropriate electrical shock. As previously described, it may become necessary to defibrillate the heart and the electrodes 32 are configured to deliver an appropriate electrical shock to defibrillate the heart.
Referring to FIG. 5C, the non-conductive member 34 extends beyond the coil wire 33 for a distance. The non-conductive member preferably is made from the same material as the dielectric material 37, typically a silicone rubber or similar material. While it is preferred that the dielectric material be made from silicone rubber, or a similar material, it also can be made from Parylene™ (Union Carbide), polyurethanes, PTFE, TFE, and ePTFE. As can be seen, the non-conductive member provides support for the dielectric material to attach the bar arms 30 of the undulating strands 22 in order to connect the strands to the electrode 32. A conductive wire 35 extends through the non-conducting member and attaches to the proximal end of the coil wire 33 so that when an electrical current is delivered from the power source 36 through conductive wire 35, the electrode coil 33 will be energized. The conductive wire 35 is also covered by non-conducting material 34.
Referring to FIG. 5D, it can be seen that the non-conductive member 34 continues to extend beyond the bottom (apex) of the cardiac harness and that conductive wire 35 continues to extend out of the non-conductive member and into the power source 36. In the embodiment shown in FIGS. 5B-5D, the cardiac harness is insulated from the electrodes by the dielectric material 37 so that there is no shunting of electrical currents by the cardiac harness 20 from the electrical shock delivered by the electrodes during defibrillation or pacing functions.
