Lung transplantation using Organ Care System

Instead of a cooler, Gary Cunningham’s new set of lungs arrived at UPMC Presbyterian in a high-tech box on wheels. The small machine kept the donor lungs functioning and “breathing” outside the body with a constant supply of blood and nutrients. The machine, made by Massachusetts-based TransMedics, allows the lungs to remain at a normal body temperature [1, 4]. It was one of the first case of using mechanical perfusion in normothermia for lung storage before transplanting. There are similar researches in kidney and liver transplantation. Read full text »
