TransMedics Group, Inc.

TransMedics makes a machine called the Organ Care System that keeps donor organs alive and healthy outside the body before transplant. Instead of packing organs in ice for transport, doctors can now connect them to this portable device that pumps blood and oxygen through them, similar to how they work inside a living person. The company makes versions for heart, lung, and liver transplants. They also provide transportation and logistics services to help get organs from donors to transplant centers.
