The Jarvik 7 is a type of artificial heart designed to replace a failing human heart. Developed by Dr. Robert Jarvik in the late 1970s, it was one of the first permanent heart assist devices. The device is made of durable materials and is powered by an external air compressor, allowing it to pump blood throughout the body. The Jarvik 7 gained significant attention when it was implanted in patients who were not candidates for heart transplants. While it has helped some individuals live longer, it also raised ethical questions about the use of artificial organs and the quality of life for patients relying on such devices.
