DONOR ORGAN PRESERVATION USING BOTH STATIC COLD STORAGE AND EX VIVO ORGAN PERFUSION

Methods, systems, and devices preserve donor organs by alternating between static cold storage and ex vivo organ perfusion. Preserving a donor organ includes refrigerating a donor organ to form a once-refrigerated donor organ, perfusing the once-refrigerated donor organ to form a once-perfused donor organ, and refrigerating the once-perfused donor organ to form a preserved, twice-refrigerated donor organ for transplantation.

MIMICKING PHYSIOLOGIC CONDITIONS DURING ORGAN OR TISSUE PERFUSION

A system is configured to perfuse one or more organs and/or associated tissues while monitoring the physiological function, testing medical devices or therapies, or both. The system includes a pump, a container, a fluid circuit, a platform, and at least one actuator. The pump is configured to generate a flow of a fluid. The container defines an interior cavity and is configured to receive at least one organ or tissue and maintain at least one environmental condition associated with the at least one organ or tissue within the interior cavity. The fluid circuit is configured to fluidically couple the pump to the at least one organ or tissue. The platform is operably coupled to the container. The at least one actuator is configured to move the platform to mimic at least one biological movement associated with the at least one organ or tissue.
