Doctors from the Texas Heart Institute have successfully replaced a patient’s heart with a device that keeps the blood flowing, thereby allowing him to live without a detectable heartbeat or even a pulse. The turbine-like device, that are simple whirling rotors, developed by the doctors does not beat like a heart, rather provide a ‘continuous flow’ like a garden hose. Craig Lewis was a 55-years-old, dying from amyloidosis, which causes a built-up of abnormal proteins. The proteins clog the organs so much that they stop working. But after the operation, with the ‘machine’ as his heart’s replacement, Lewis’ blood continued to spin and move through his body. When doctors put a stethoscope to his chest, no heartbeat or pulse can be heard (only a ‘humming’ sound). This is proof that “human physiology can be supported without a pulse”.
