The World's Oldest Artificial Heart

In honour of Valentine's Day, Gizmodo presents you with the Liotta-Cooley heart, the world's first totally artificial blood pumper.

Developed by Dr Domingo Liotta and implanted by Dr Denton A. Cooley on April 4, 1969, the Liotta-Cooley heart kept a 47-year-old man alive for three full days before a human organ became available. And to this day, it's our most impressive cure for a broken heart. [Smithsonian]
