Title
(EN) METHOD AND APPARATUS FOR ASSISTING A HEART
(FR) PROCEDE ET APPAREIL DESTINES A AIDER LE COEUR
Abstract
(EN)
An apparatus and method for assisting a heart to pump blood includes a housing that defines an internal chamber for receiving a heart. The housing (12) has a first opening (38) to supply fluid to the internal chamber of the housing. Uniform pressure is applied to at least a majority portion of an exterior ventricular surface of a heart that is placed within the internal chamber (34), so that the heart is substantially uniformly deformed to simulate a systolic phase.
(FR)
La présente invention concerne un appareil et un procédé destinés à aider le coeur à faire circuler le sang. L'appareil comprend un logement qui définit la cavité intérieure recevant le coeur. Le logement (12) possède une première ouverture (38) qui permet d'amener le liquide dans la cavité interne du logement. Une pression uniforme est exercée sur au moins la majeure partie de la surface extérieure du ventricule du coeur placé à l'intérieur de la cavité interne (34), de sorte que le coeur se déforme uniformément pour simuler une phase systolique.
