World's 1st permanent artificial heart in use since 1982
On December 2, 1982, the world's first permanent artificial heart replaced a 61-year-old's heart, who survived for 112 days. Developed by American researcher Robert Jarvik, the device Jarvik-7 was permanently implanted in four others, where the second patient lived 620 days. Since then, over 350 patients have received it as a temporary heart while awaiting human heart transplants.
