CA 2236557
A stent delivery method and system are disclosed. The system generally includes an elongated delivery sheath and a perfusion catheter disposed within a sheath lumen of the sheath having an expandable member on its distal extremity. The sheath includes perfusion ports to maintain blood flow to perfusion ports in the catheter during delivery of the stent. A manipulating device is provided at the proximal end of the delivery system to effect relative axial movement between the sheath and the catheter so as to expose the stent mounted on the expandable member on the catheter within a body lumen such as a coronary artery and to allow the expansion of the stent by the expansion of the expandable member.
Méthode et système de livraison d'un introducteur. Le système comprend généralement une gaine de livraison allongée et un tube de perfusion placé à l'intérieur d'une lumière de la gaine ayant un élément extensible sur son extrémité distale. La gaine comprend des orifices de perfusion pour maintenir l'écoulement du sang aux orifices de perfusion du tube pendant la livraison de l'introducteur. Un dispositif manipulateur est fourni à l'extrémité proximale du système de livraison pour effectuer un déplacement axial relatif entre la gaine et le tube de façon à exposer l'introducteur monté sur l'élément extensible du tube à l'intérieur d'une lumière du corps, comme une artère coronaire, et à permettre la dilatation de l'introducteur par la dilatation de l'élément extensible.
