Robert Koffler Jarvik is an #American #surgeon and #inventor who invented the #Jarvik-7, the first #artificial #heart used as a #permanent #implant in a #human.

On 2 Dec 1982, terminally ill #cardiac #patient Barney Clark, was the first to have his heart #replaced with a Jarvik-7. The surgeon was William C. DeVries.

The #aluminum and #plastic device replaced the two lower chambers (ventricles) of his natural heart. Two rubber #diaphragms acted to #pump blood, powered by hoses to an external #compressor. #Oxygenation occurred naturally in the patient's lungs. After 112 days, Clark died from physical complications caused by the implant. Several more patients had no better results.

The Jarvik-7 problems remained unsolved and its permanent use was abandoned.
