Inventors: Alexis Carrel, Charles Lindbergh, and Otto Hopf
How it began: There was a need to keep whole organs alive outside the body in an artificial environment during surgical studies of transplantation.
What it does: An organ in a closed chamber of the hand-blown Pyrex glass apparatus is connected to a glass tubing system that mimics blood circulation. Powered by a separate pump and rotary valve for creating pulsating pressure, the apparatus perfuses an organ continuously with a synthetic blood-like fluid that can be renewed aseptically and filtered automatically.
Impact on medical science: This pump was the demonstration that life could be sustained by a machine that works very much like the heart. It led to developing implantable synthetic hearts and heart-lung machines for open heart surgery in the 1950s.
