A vascular device (10) comprising a body movable from a collapsed insertion position to an expanded position having a larger cross-sectional dimension. The body includes a plurality of struts. At least two elongated struts (18) extend distally from the body. A plurality of vessel engaging members extend outwardly from the body for engaging the internal wall of a vessel. A valve (40) is movable between a collapsed delivery position and an expanded placement position, wherein at least a portion of the valve extends distally from the body in the delivery and placement positions and the elongated struts engage a distal portion of the valve in the placement position of the valve to retain the valve.

Cette invention concerne un dispositif vasculaire (10) comprenant un corps pouvant passer d'une position d'insertion aplatie à une position gonflée ayant une plus grande dimension transversale. Le corps comprend une pluralité de supports. Au moins deux supports (18) de forme allongée s'étendent distalement à partir du corps. Une pluralité d'éléments de contact avec le vaisseau s'étend vers l'extérieur à partir du corps pour venir en contact avec la paroi interne d'un vaisseau. Une valve (40) peut passer d'une position d'introduction aplatie à une position d'installation gonflée, au moins une partie de la valve s'étendant distalement à partir du corps dans les positions d'introduction et d'installation et les supports de forme allongée venant en contact avec une partie distale de la valve en position d'installation pour la retenir.
