An apparatus for transporting and maintaining an excised heart (18) in condition for transplantation includes a container (12) defining a chamber (14) for receiving the heart (18), and a body of physiological fluid (16) disposed in the chamber (14). A pump (80) is provided for pumping the fluid into the heart, and a source of oxygen (30) under pressure. Oxygen flow structure continuously directs flow of pressurized oxygen (30) into the fluid thereby to oxygenate the fluid and to maintain the pressure in the chamber (14) at a pressure above atmospheric pressure. An aorta supply line (90) directs fluid from the pump (80) to the aorta and thence into the coronary arteries to force perfusion of the vascular bed of the heart (18).

L'invention concerne un appareil de transport et de maintien d'un coeur excisé (18) dans les conditions nécessaires pour une transplantation. Cet appareil comprend un contenant (12) définissant une enceinte (14) destinée à recevoir le coeur (18) et un volume de liquide physiologique (16) disposé dans l'enceinte (14). On dispose d'une pompe (80) permettant de pomper le liquide dans le coeur et d'une source d'oxygène sous pression (30). La structure d'écoulement d'oxygène permet de diriger en continu un écoulement d'oxygène sous pression (30) dans le liquide afin d'oxygéner le liquide et de maintenir la pression dans l'enceinte (14) à une valeur supérieure çà celle de la pression atmosphérique. Un conduit d'alimentation de l'aorte (90) dirige le liquide de la pompe (80) vers l'aorte et par conséquent dans les artères coronaires afin de provoquer la perfusion du lit vasculaire du coeur (18).
