This man named, Craig Lewis was 55-year-old and was dying due to a serious heart problem. Even a pacemaker couldn’t help. He was admitted to the Texas Heart Institute, where two doctors proposed a revolutionary plan of installing a device that will continually pump the blood without any pulse.

Within a day after the operation, in the year of 2011, by removing the entire heart and replacing it with a “continuous flow” device, by Dr. Billy Cohn and Dr. Bud Frazier, the patient was up and better. His life was saved.
