Video: The Doctors Who Made the No-Pulse Heart

Heart Stop Beating is a three-minute documentary film about the no-pulse, continuous-flow artificial heart, which Dan Baum writes about in our Future of Medicine issue. It tells the story of Billy Cohn & Bud Frazier, two visionary doctors from the Texas Heart Institute, who in March of 2011 successfully replaced a dying man's heart with the device they developed, proving that life was possible without a pulse or a heart beat.
