Knock, knock! Who’s there? It’s the pig lung you ordered! Lung Biotechnology, a subsidiary of United Therapeutics, has entered into a fifteen-year agreement with Chinese manufacturer EHang to purchase 1,000 drones to be used for delivery of manufactured lungs and other organs to patients in need. The use of the drone is intended to increase delivery speed so that a xenotransplantation organ can be more easily delivered within its viability window. The order of drones is contingent upon winning approval from the FDA and the U.S. Federal Aviation Administration for both the organs and the delivery vehicles. If this delivery system is successful, one could imagine drone delivery of medical supplies having a significant impact on patient treatment and clinical trial protocols.
