This old machine has a hand crank and the wheel spins. There are various types of tests that can be done with it, but who wants to do that. The design of this object looks great just hanging out in your space. The wheel is old but was stored the whole time so the paint is fresh and bright on the aluminum disk. A thumb knobs releases the wheel via a central bolt and you can put other discs of your choice. Measures: 27" H x 11"
Dr. Robert Jarvik invented the first artificial heart in 1982. I really like the story of Jarvik. It is the story of persistence and accomplishment--after having been rejected numerous times out of medical school he finally made it in University of Utah and developed this heart! This early model was hooked up to a large battery pack the size of a refrigerator and made a constant clicking sound. Barney Clark a 61 year old dentist was the first to get one of these and survived 112 days on it. It is a fascinating and pioneering piece of medical history. Piece came from a cardiologist personal collection and is a working model used to study the Jarvik-7 before implants and also to show candidates how it works. Has 'not for implant' securely built in the model chambers so as not to accidentally end up in someone. You can visit one in the Smithsonian or have one in your private collection.
