Denton A. CooleyBorn 22 Aug 1920. Dr. Denton A(rthur) Cooley is an American surgeon and heart-transplant pioneer who was the first to implant an artificial heart in a human. In 1960s he performed delicate surgery on the hearts of infants with congenital heart disease, and was the first surgeon to successfully remove pulmonary embolisms. On 3 May 1968, Cooley performed his first human heart transplant. On 4 Apr 1969, because no donor heart was available for a dying 47-year-old patient with diseased heart muscle, he implanted a mechanical heart made of silicone as a temporary measure. The experimental artificial heart was used for 65 hours, and was removed when a human heart became available.« |
