Medical is a field, who has always contributed positively by reducing the level of pain in every form, to the humanity by using its knowledge and technology. The history is full of contributions made by various scientists and allied people of this field. One of these contributions is formation of artificial heart. In this paper we will take a look on various aspects this amazing invention.
An account in which structure and other related info is given on The Franklin Institutes Science Museum (1996) is in these words: “Medical scientists have developed electronic devices such as defibrillators, pacemakers, and artificial heart models that can keep the patient alive until a heart becomes available. One of the best known devices is the "Jarvik-7" artificial heart, named for its designer Robert K. Jarvik, an American physician. Designed to function like the natural heart, the Jarvik-7 has two pumps (like the ventricles), each with a disk-shaped mechanism that pushes the blood from the inlet valve to the outlet valve.
The action of the artificial heart is entirely similar to the action of the natural heart. There is, however, one huge difference: the natural heart is living muscle, while the artificial heart is plastic, aluminum, and Dacron polyester. As a result, the artificial heart needs some external source of "life." An external power system energizes and regulates the pump through a system of compressed air hoses that enter the heart through the chest. Since the system is cumbersome and open to infection, the use of an artificial heart is meant to be temporary.”
Various attempts were made in the area of its formation. The person to whom the credit of starting this cycle goes is Dr. Paul Winchell. On website of about, Inc (2006), these words have been used
“Artificial hearts date back to the mid-1950s when Dr. Paul Winchell first patented an artificial heart. “......................
