The present invention is to provide an improved device to hold an anastomotic site of coronary artery for the bypass surgery; to provide said device wherein the coronary artery bypass operation can be quickly, and accurately performed on the beating heart by firmly and atraumatically holding said anastomotic site motionless and bloodless. That is to say, the characteristic feature of the present invention is in that the coronary artery can be stably held motionless without need to forcedly compress the heart surface. This is accomplished with a circular flexible suction device which surrounds the target artery, and whose center is open to expose the anastomotic site. The device is suctioned to the heart surface by drawing off the air in the flexible circular channel, creating negative pressure.
L'invention concerne un dispositif perfectionné pour maintenir un site anastomotique de l'artère coronaire pour la chirurgie de pontage. Ce dispositif permet d'effectuer l'opération de pontage de l'artère coronaire avec rapidité et précision sur le coeur battant en maintenant immobile et exsangue ledit site anastomotique de manière ferme et atraumatique. La présente invention est caractérisée en ce que l'artère coronaire peut être maintenue immobile de manière stable sans recourir à une compression forcée de la surface du coeur, grâce à un dispositif d'aspiration souple circulaire qui entoure l'artère cible et dont le centre est ouvert pour mettre à découvert le site anastomotique. Ce dispositif est plaqué par aspiration à la surface du coeur par purge de l'air contenu dans le canal circulaire souple, ce qui crée une dépression.
