The present invention provides a catheter apparatus (1), an improved introducer system (80), a methodology for creating a bypass on-demand between an unobstructed blood vessel such as the aorta, an obstructed blood vessel, and an obstructed coronary artery in vivo using a prepared shape-memory alloy cuff (300), and a graft segment (460) in tandem as a shunt. The apparatus (1) allows the placement, and creation of single or multiple bypass grafts without use of a heart/lung machine, and without need for stopping the heart of the patient during the coronary artery bypass surgery.
L'invention concerne un cathéter (1), un système (80) d'introduction perfectionné, ainsi qu'une technique de création, à la demande et in vivo, d'un pontage entre un vaisseau sanguin non obstrué, tel que l'aorte, un vaisseau sanguin obstrué, et une artère coronaire obstruée, à l'aide d'une coiffe (300) en alliage à mémoire de forme et d'un segment greffon (460), placés en tandem, en tant que dérivation. Ce cathéter (1) permet de placer et de créer une ou plusieurs greffes de pontage, sans qu'il soit nécessaire d'utiliser un coeur/poumon artificiel ni d'arrêter le coeur du patient, pendant la chirurgie de pontage de l'artère coronaire.
