the first clinical use of an artificial heart designed for permanent implantation rather than a bridge to transplant occurred in 1982 at the university of utah. artificial kidney pioneer willem johan kolff started the utah artificial organs program in 1967. there, physician-engineer clifford kwan-gett invented two components of an integrated pneumatic artificial heart system: a ventricle with hemispherical diaphragms that did not crush red blood cells (a problem with previous artificial hearts) and an external heart driver that inherently regulated blood flow without needing complex control systems. independently, paul winchell designed and patented a similarly shaped ventricle and donated the patent to the utah program. throughout the 1970s and early 1980s, veterinarian donald olsen led a series of calf experiments that refined the artificial heart and its surgical care. during that time, as a student at the university of utah, robert jarvik combined several modifications: an ovoid shape to fit inside the human chest, a more blood-compatible polyurethane developed by biomedical engineer donald lyman, and a fabrication method by kwan-gett that made the inside of the ventricles smooth and seamless to reduce dangerous stroke-causing blood clots. on 2 december 1982, william devries implanted the artificial heart into retired dentist barney bailey clark (born 21 january 1921), who survived 112 days with the device, dying on 23 march 1983. bill schroeder became the second recipient and lived for a record 620 days.

in 2016, syncardia filed for bankruptcy protection and was later acquired by the private equity firm versa capital management.









































a january 2019 report in europe stated that "there is only one fully artificial heart currently in the market, developed by us-based syncardia".

another u.s. team has a prototype called the 2005 magscrew total artificial heart. teams in japan and south korea are also racing to produce similar devices.
