Patent attributes
Method and system for organ preservation. According to one aspect, an organ may be preserved by being perfused with an in situ generated preserving gas. The organ may be, for example, a human or porcine pancreas, and perfusion of the pancreas may be anterograde, retrograde, ductal, anterograde/ductal, or retrograde/ductal. The preserving gas used to perfuse the organ may be dissolved in a liquid and then administered to the organ as a gas/liquid solution or may be mixed with one or more other gases and then administered to the organ as a gas/gas mixture. The preserving gas may be, for example, oxygen gas generated in situ using an electrochemical oxygen concentrator. According to another aspect, an organ preservation system may include an electrochemical oxygen concentrator having a water vapor feed, as well as auxiliary equipment to control and measure delivery pressure, flow, temperature and humidity.
