Currently, coolers are used to transport organs for transplantation. The problem is that the cooler only slows down the organs deterioration since blood containing nutrients and oxygen stops being supplied to it. Because of this doctors have a short window of time (5 to 10 hours for lungs and 4 to 6 hours for hearts) to remove and transplant the organ. Because of this organs go wasted because they’re simply too far away from the people who need them. TransMedics is developing the Organ Care System (lung in a box) that keeps the organ “breathing” and supplied with blood. It’s currently still being studied by has successfully been part of 12 lung transplants.
