Cardio therapeutic heart sack

An implantable heart sack for the treatment of heart ailment that is prepared from biocompatible, biostable and implantable elastomers selected from the group consisting of polyetherurethane, polycarbonateurethane, silicone, polysiloxaneurethane, polyfluoroethylene, ethylene propylene terpolymer, or hydrogenated poly(styrene-butadiene) copolymer and the said heart sack is reinforced with the biocompatible, biostable and implantable braids, cords, fibers, monofilament, wires, yams, cloth, woven fabric, non-woven fabrics or elastomers prepared from the group consisting of polyamide, polyimide, polyester, polypropylene, and polyurethane, and has holes and grooves for the pulmonary artery, aorta, other blood vessels, pacemaker leads, defibrillation leads, and other therapy devices and has slits which enable to the heart sack to wrap around the heart and blood vessels and is equipped or can be equipped with either pacemaker leads, defibrillation leads or both;

• and the said leads were prepared from braids, cords, fibers, monofilament, wires, yarns, cloth, woven, non-woven fabrics, cylindrical tubes, films or laminated films of biocompatible, biostable, implantable polymers selected from the group consisting of polyamide, polyimide, polyester, and polypropylene;
• and were coated, deposited or plated with stainless steel or highly electrically-conductive noble metal;
• and the said noble metal is selected from the group consisting of gold, platinum, rhodium, and their alloys, and the said metal coated articles are encased in a multi-lumen sleeve or coaxial insulation tubes;
• and the leads are fabricated in such a way that one end of the leads or cable is equipped with the connectors to a pacemaker or a defibrillator, and the noble metal coated fibers and/or films protruding from another end of the multi-lumen leads or coaxial leads for a designated length are bonded or mounted into grooves of the heart sack to become electrode, or bonded onto a insulating film or a sheet to form electrode then bonded with the heart sack or mounted into the heart sack to become the pacemaker or defibrillation electrode;
• or the said metal coated articles are connected to platinum or platinum rhodium alloy electrodes, then placed on the inner side of the heart sack to form detachable or built-in pacemaker or defibrillation leads.
