  • Compositions, methods and devices for maintaining an organ
    Patent number: 9756851
    Abstract: Compositions, methods, systems/devices and media are provided for maintaining a harvested organ in a functioning and viable state prior to implantation. The organ perfusion apparatus includes a preservation chamber for storing the organ during the preservation period. A perfusion circuit is provided having a first line for providing an oxygenated fluid to the organ, and a second line for carrying depleted fluid away from the organ. The perfusion apparatus also includes a device operably associated with the perfusion circuit for maintaining the organ at a substantially normothermic temperature.
    Type: Grant
    Filed: February 24, 2017
    Date of Patent: September 12, 2017
    Assignee: THE DEPARTMENT OF VETERAN AFFAIRS
