An aid for a coronary artery bypass operation, wherein a slit (8) in which a guide wire (3) is inserted is formed in the peripheral wall of a tubular member (2) inserted into a Left anterior descending branch. A thread (15) is wound on the peripheral wall of the tubular member (2) and fixed so that a knot (17) formed by the fixing is positioned on the approximately opposite side of the slit (8) in the peripheral wall. After the tubular member (2) is inserted into the Left anterior descending branch by the guide of the guide wire (3), the guide wire (3) is extracted. The thread (15) is gently pulled out to rotate the annular member (2) around its axis so as to cover the slit (8) by the inner surface of the Left anterior descending branch. After a graft blood vessel is anastomosed, more than half, around the incised part of the Left anterior descending branch, the thread (15) is strongly pulled out to take out the tubular member (2) from the bifurcated vessel. Thus, the graft blood vessel can be completely anastomosed around the incised part of the bifurcated vessel.

La présente invention concerne un instrument pour le pontage de l'artère coronaire consistant en une fente (8), dans laquelle est inséré un guide-fil (3), formée dans la paroi périphérique d~un élément tubulaire (2) inséré dans une branche descendante antérieure gauche. Un fil (15) est enroulé sur la paroi périphérique de l~élément tubulaire (2) et fixé de telle sorte qu~un nAEud (17) formé par la fixation soit positionné approximativement sur le côté opposé à la fente (8) dans la paroi périphérique. Après l~insertion de l~élément tubulaire (2) dans la branche descendante antérieure gauche par le guide du guide-fil (3), le guide-fil (3) est extrait. Le fil (15) est délicatement tiré pour faire tourner l~élément annulaire (2) par rapport à son axe de manière à couvrir la fente (8) par la surface intérieure de la branche descendante antérieure gauche. Une fois qu~un vaisseau sanguin greffé est anastomosé de plus de la moitié autour de la partie incisée de la branche descendante antérieure gauche, le fil (15) est fortement tiré pour retirer l~élément tubulaire (2) du vaisseau bifurqué. Ainsi, le vaisseau sanguin greffé peut être entièrement anastomosé autour de la partie incisée du vaisseau bifurqué.
