The Jarvik-7 artificial heart
The first permanent artificial heart, called the Jarvik-7, designed by Dr. Robert Jarvik, was implanted into a 61-year-old retired dentist. Because the Jarvik-7 was kept beating by an external compressor attached by hoses, the patient was required to remain immobile. The patient survived for 112 days after the device was implanted.
