With the arrival of twentieth-century technology, medical professions were able to think seriously about creating artificial replacements for damaged human hearts that no longer functioned effectively. In 1957, Dr. Willem Kolff created the first artificial heart and implanted it in a dog, who promptly died from the experiment. Still, animal research continued, and, in 1969, Dr. Denton Cooley implanted the first artificial heart into the body of a human. The device, made largely of plastic, only had to function for a brief period of time, while the patient awaited a transplanted human heart. In 1979, Dr. Robert Jarvik patented the first artificial heart. Three years later, the Jarvik heart, as it came to be called, was implanted in the body of Barney Clark, a retired dentist dying of heart disease. Clark lived for 112 days after the surgery, and his survival raised hopes for the future success of artificial hearts.
