Patent

CA 2710561

An intraluminal prosthesis includes an outer three-dimensional (3D) anti- migration structure that is attached to the outer wall of a fully covered or partially covered stent to prevent migration and still allow stent removal at a later period of time. A method of manufacturing the intraluminal prosthesis includes attaching the anti-migration structure by usage of a polymer such as polyurethane.

L'invention concerne une prothèse intraluminale comprenant une structure d'anti-migration tridimensionnelle (3D) externe qui est fixée sur la paroi externe d'une endoprothèse vasculaire entièrement couverte ou partiellement couverte pour empêcher la migration et permettre malgré cela le retrait de l'endoprothèse vasculaire à un moment ultérieur. Le procédé de fabrication de la prothèse intraluminale inclut la fixation de la structure d'anti-migration par utilisation d'un polymère tel que le polyuréthanne.
