1. Artificial Heart

One solution that researchers have pursued since the late 1960s is an artificial heart. Perhaps the most influential device was kick-started by Willem Kolff, the physician-inventor who produced the first kidney dialysis machine. Kolff invited a fellow medical engineer, one Robert Jarvik, to work with him at the University of Utah, and the result was the Jarvik-7. Made up of two pumps, two air hoses and four valves, the Jarvik-7 was more than twice as big as a normal human heart and could only be implanted in the biggest patients – mainly adult men. It had wheels, was as big and heavy (although not as tall) as a standard household refrigerator, and was normally connected to sources of compressed air, vacuum and electricity.

In 1982, Jarvik and Kolff won approval from the US Food and Drug Administration to use it in human patients and implanted it that same year. Their first patient was a 61-year-old dentist called Barney Clark, who lived on the Jarvik-7 for 112 days. A second patient was implanted in 1984 and died after 620 days. History records a total of five patients implanted with the Jarvik-7 for permanent use, all of whom died within 18 months of the surgery from infections or strokes...
