CA 2285016

A stent graft delivery system and methods for use are provided for use in treating aneurysms occurring in single and bifurcated lumen hollow body organs or vessels, and for treating arteriovenous fistulas. A graft delivery component (10) provides a clinician with complete control over the location of a graft at any time prior to implantation of stents, even when the graft is deployed from its introducer catheter. The graft delivery component (10) includes a plurality of radially expandable fingers (11-16) that releasably engage the graft, while the stent delivery component (10) includes a small diameter introducer catheter and permits a wide range of conventional stent designs to be used to permanently fix the graft in position.

L'invention concerne une système de pose de greffe et prothèse endovasculaire et des méthodes d'utilisation dans le traitement d'anévrismes d'organes ou de vaisseaux creux à lumière unique ou fourchue, et dans le traitement de fistules artério-veineuses. Un composant de pose de greffe (10) permet à un clinicien d'avoir une commande totale sur l'emplacement d'une greffe à n'importe quel moment avant l'implantation de prothèses, même lorsque la greffe est déployée à partir de son cathéter introducteur. Le composant de pose de greffe (10) comprend plusieurs doigts extensibles radialement (11-16) coopérant de manière libérable avec la greffe, tandis que le composant de pose de prothèse endovasculaire (10) comprend un cathéter introducteur de diamètre réduit et permet l'utilisation d'une large gamme de modèles de prothèses endovasculaires classiques pour maintenir de manière permanente la greffe en position.
