![]() They had kept a man alive in the final stages of heart failure for well over three months. After his death, more than 1,300 people, including political figures, members of the governing council of the Latter-Day Saints (Mormon) Church, of which Clark was a member, many of his doctors, and media representatives from around the world attended his funeral in Seattle, Washington.ĭeVries and the Utah group pronounced the Clark experiment a success. After a few weeks on the machine, his emotional and cognitive state deteriorated severely, and on more than one occasion, he asked that the artificial heart be turned off. ![]() ![]() He suffered a wide range of complications that required three additional surgical procedures. But Clark followed a very rocky course during the 112 days he lived with the Jarvik-7 device. In the days after the implant, the healthcare team made many optimistic pronouncements to the media about Clark's chances for survival. Jarvik and DeVries spent many hours speaking with the media about the operation, the device, and their patient's health status. When his heart began to fail on December 1, he was taken to the operating room, and after a nine-hour operation he became the first human being to receive an artificial heart intended as a permanent replacement for his own. He signed the eighteen-page consent form the night he was admitted to the hospital. Clark, a retired dentist who had been admitted to the University of Utah Medical Center on November 29, 1982, with cardiomyopathy, was deemed to be an ideal candidate for the first implant of the Jarvik heart (Fox and Swazey) as he was educated, enthusiastic, and had a very supportive family. ca 1984 ID Number 2010.0200.01.01 accession number 2010.0200 catalog number 2010.0200.01 Object Name heart, artificial Physical Description metal (overall material) polyurethane (overall material) polyvinylchloride (overall material) dacron (overall material) velcro (overall material) Measurements overall, as stored: 3 3/8 in x 5 3/8 in x 6 5/8 in 8.5725 cm x 13.6525 cm x 16.8275 cm overall: 10 cm x 13.Barney B.

The highly publicized artificial heart operations brought attention to the triumphs of scientific technology as well as its limitations, and costs, both literal and figurative. Jarvik also experimented with materials using polyurethane Biomar to create surfaces inside the housing which prevented blood thrombosis or clotting. His improvements allowed the correct amount of blood 100cc's, to circulate through the body. The addition of two extra rubber bellows allowed for more vigorous blood flow. Jarvik also added a third and fourth bladder to each ventricle creating more flexibility and durability. in the Kolff laboratory who changed the TAH from a sphere to an elliptical shape allowing it to fit more easily into the chest cavity. Numerous scientists and engineers worked on the development of the artificial heart, but it was Robert Jarvik, M.D. He was a research associate in the Kolff laboratory while still in medical school. ![]() He received his medical degree from the University of Utah, and completed his residency at the Duke Medical Center. William DeVries, a cardio-thoracic surgeon became recognized around the world as the surgeon who implanted the first Jarvik-7 in dentist Barney Clark in December 1982. Haydon lived with the artificial heart for 488 days. The TAH is driven by an external pneumatic pump, the Utah drive System II. Each ventricle contains a flexible diaphragm constructed of multi layered polyurethane. The Jarvik-7 TAH has a right and left ventricle with four tilting disc valves. Haydon lived with the implanted blood pump for 488 days. The operation took place at the Humana Heart Institute International in Louisville, Kentucky. Description This dissected Jarvik-7 Total Artificial Heart (TAH), was implanted in Murray Haydon, the third artificial heart recipient, July 20, 1986.
