Abstract
A device for hypothermic perfusion of a cardiac organ comprising a first sealed tank able to contain a physiological liquid, a second sealed tank communicating, in a sealed manner, with an internal volume of the first tank via a nozzle, a device for refrigerating the first tank and keeping the first tank at a substantially constant temperature and a device for intermittently pressurizing the internal volume of the first tank. The first tank communicates with the pressurizing device by way of a conduit connecting an interior of the first tank to the pressurizing device to permit pressurization of the internal volume of the first tank, and of the physiological liquid inside the first tank, in order to perform perfusion of the organ. The second tank comprises a safety element formed by an overflow outlet duct which communicates with the first tank and includes a non-return valve.
