Transmedics Group, Inc.
A medical technology company that makes the Organ Care System, a portable device that keeps donor hearts, lungs, and livers warm, beating, and functioning outside the body during transport—a shift from the old method of packing organs on ice. Founded in 1998 by cardiac surgeon Dr. Waleed Hassanein, the company's name blends "transplant" and "medics." Its machines let transplant teams assess and preserve organs in a near-living state while they travel to recipients.
