Timeline of United States inventions (1946–1991)
An artificial heart is implanted into the body to replace the biological heart. On July 3, 1952, 41-year-old Henry Opitek suffering from shortness of breath made medical history at Harper University Hospital at Wayne State University in Michigan. The Dodrill-GMR heart, considered to be the first operational mechanical heart, was invented by Dr. Forest Dewey Dodrill and successfully inserted into Henry Opitek while performing open heart surgery. In 1981, Dr. Robert Jarvik implanted the world's first permanent artificial heart, the Jarvik 7, into Dr. Barney Clark. The heart, powered by an external compressor, kept Clark alive for 112 days. The Jarvik heart was not banned for permanent use. Since 1982, more than 350 people have received the Jarvik heart as a bridge to transplantation.
