A method for positioning an intraluminal graft within a branching vessel in a patient's body is described. The method is particularly applicable to the appropriate positioning of a trouser graft so that it bridges an aneurism which extends from a single vessel, such as the aorta, into one or more divergent vessels, for example, an iliac artery. The method can comprise the steps of placing a first graft (10), that bifurcates in a pair of tubular sections (19a, 19b) into the pre-branching portion of a vessel (11) through one of the post-branching portions of the vessel (12, 13), positioning a second tubular graft (10b) into one of the post-branching portions (12) and connecting it to one of the tubular sections of the first graft (19a), and positioning a third tubular graft (10a) into the other of the post-branching portions (11) and connecting it to the other of the tubular sections of the first graft (19b).
L'invention concerne une méthode permettant de positionner un greffon endo-luminal à l'intérieur d'un vaisseau ramifié dans l'organisme d'un patient. La méthode peut notamment être appliquée au positionnement approprié d'un greffon de type pantalon, de façon que celui-ci ponte un anévrysme partant d'un vaisseau unique, tel que l'aorte, et s'étendant à un ou plusieurs vaisseaux divergents, tel qu'une artère iliaque. Pour ce faire, on place un premier greffon (10), qui bifurque en une paire de sections tubulaires (19a, 19b), dans la partie pré-ramification du vaisseau (11) par l'intermédiaire de l'une des parties post-ramification dudit vaisseau (12, 13); on positionne un second greffon tubulaire (10b) dans l'une des parties post-ramification (12) et on le relie à l'une des sections tubulaires du premier greffon (19a); on positionne un troisième greffon tubulaire (10a) dans l'autre partie post-ramification (11) et on le relie à l'autre section tubulaire du premier greffon (19b).
