This allows the patient freedom to move about.įive hospitals around the country are participating in clinical trials with the AbioCor. To recharge the battery, it simply needs to be plugged it into an AC outlet. This is a completely interna device that comes with a pack of rechargeable batteries about the size of a VCR tape worn about the waist that will power the heart, transmitting current through the skin without wires. Today, the device that is seen as hope for a critically ill heart patient is the AbioCor. Until recently, they were used strictly as a bridge to a transplant. It doesn't replace the entire heart, just the function of the left ventricle of the heart, which has the strongest pumping action in the heart. Other patients went on to receive the Jarvik-7, but only as a temporary device while awaiting heart transplants.īecause of complications with the Jarvik-7, further research led to the development of the L-VAD, which stands for "left ventricular assisted device." It is a heart-assisted pump implanted to help a patient survive while waiting for a heart transplant. It also required patients to stay constantly tethered to a machine the size of a refrigerator. There were several problems associated with the Jarvik-7, such as deaths caused from blood clots and infection. He lived 112 days after receiving the Jarvik-7. On December 2, 1982, an artificial heart was implanted in Barney Clark. It was another 13 years before the next major breakthrough. The patient got a heart transplant 3 days later and then died 1 1/2 days later. Three years later, a total artificial heart was implanted in a patient by Dr. Michael DeBakey successfully implanted a partial artificial heart. There is one internal battery, which allows patients to be without the external battery for a short period of time (about 1/2 hour). The power comes through the skin and batteries are on the outside. Others in the past made noise, but this one sounds like a natural heart. He says it's a totally quiet device that can be powered without piercing the skin. This describes 50,000-70,000 Americans annually. The AbioCor device is for people whose hearts are destroyed and are in need of a new heart. Frazier says both the AbioCor and another artificial heart, the Jarvik 2000, are implanted under strict guidelines.
