Patent

CA 2257989

The present invention provides a catheter apparatus (2), an introducer system (120), and a methodology for creating a vascular bypass on-demand between an unobstructed blood vessel, such as the aorta and an obstructed blood vessel (502) such as an obstructed coronary artery in vivo using a previously excised vascular segment as a shunt. The invention allows the placement and creation of single or multiple vascular grafts (300) without use of a heart/lung machine and without need for stopping the heart of the patient during the coronary artery bypass surgery.

La présente invention se rapporte à un dispositif cathéter (2), à un système introducteur (120) et à un procédé de création in-vivo d'un pontage vasculaire sur demande entre un vaisseau sanguin non obstrué tel que l'aorte et un vaisseau sanguin (502) obstrué tel qu'une artère coronaire obstruée, ledit procédé consistant à utiliser un segment vasculaire préalablement excisé en tant que shunt. L'invention permet la mise en place et la création de greffes (300) vasculaires simples ou multiples sans recours à un coeur-poumon artificiel et sans nécessiter l'arrêt du coeur du patient au cours d'une intervention de pontage aorto-coronarien.
