Jarvik passed away at the age of 79 in 2025, leaving behind a profound impact on biomedical engineering and cardiac care. His life and work continue to inspire researchers and clinicians striving to improve quality of life for patients with heart failure through technological innovation.
Early Life and Education
Robert Jarvik was born in Midland, Michigan, and showed an early interest in design and innovation. Initially, he enrolled in architecture school at Syracuse University, but his career path shifted after his father developed cardiovascular disease, which inspired him to pursue medical-related studies. Despite his interest, Jarvik faced significant challenges in gaining admission to medical schools, being rejected by 15 institutions across the United States. He eventually was accepted at the University of Bologna in Spain, where he studied but did not complete a degree.
Determined to contribute to medical science, Jarvik later returned to formal education and earned a degree in medical engineering from New York University. In 1976, motivated by the encouragement of Willem Kolff and his own passion for artificial heart development, Jarvik earned his M.D. degree, which solidified his foundation in both engineering and medicine. This educational background enabled him to co-found the bioengineering company Symbion in 1977 alongside Kolff, with the goal of researching and developing artificial hearts.
Career
Robert K. Jarvik was an American scientist and researcher best known for his role in designing the Jarvik-7, one of the first successful artificial hearts. Jarvik’s most notable achievement was the development of the Jarvik-7 artificial heart, a mechanical device designed to replace a diseased human heart either temporarily or permanently. The Jarvik-7 featured two pumps mimicking the ventricles of a natural heart, with disk-shaped mechanisms to push blood through valves, although unlike a natural heart, it was made from materials such as plastic, aluminum, and Dacron polyester. In 1982, the first implantation of the Jarvik-7 was performed on patient Barney Clark by William DeVries of the University of Utah, with Jarvik assisting in the seven-and-a-half-hour surgery. Clark lived for 112 days with the device, a landmark event that garnered worldwide attention and demonstrated the potential of total artificial heart technology.
The Jarvik-7 significantly contributed to the field by prolonging the lives of nearly 50 patients during the mid-1980s and providing valuable insights into the development and improvement of artificial organs. Despite some criticism claiming the device was a failed experiment, it actually achieved the highest success rate of any artificial heart or assist device at the time. The complications that arose were largely due to the challenges in managing patient care rather than the device itself.
Following the Jarvik-7, Robert Jarvik continued his work in artificial heart technology, developing smaller ventricular assist devices (VADs), including the Jarvik 2000, which aimed to support the natural heart rather than replace it entirely. This represented a significant advance in cardiac support devices, providing new opportunities to treat heart failure patients and improve their quality of life.
Beyond his work on artificial hearts, Jarvik conducted research on other artificial organs and authored over 60 technical articles. He held multiple patents related to medical devices and received numerous awards throughout his career, including being named inventor of the year in 1982 by the Intellectual Property Owners trade association. His pioneering work helped pave the way for continued innovations in cardiac assist devices and total artificial hearts.
