CA 2360175

A vascular valve prosthesis is formed by suturing, preferably in a running fashion, a vein valve segment that has been substantially trimmed to reduce a wall thickness, and thus a radial dimension thereof, to a self-expanding stent. The thus formed bio-prosthesis (18) is percutaneoulsy placed to treat chronic venous insufficiency when it is due to incompetent venous leaflets.

Cette invention se rapporte à une prothèse de valvule du système vasculaire, que l'on obtient en suturant, de préférence par suture continue, un segment de valvule veineuse ayant été taillé pour en réduire l'épaisseur de la paroi et, partant, sa dimension radiale, à un extenseur autodilatable. La bioprothèse ainsi formée (18) est implantée par voie percutanée, pour traiter tout insuffisance veineuse chronique due à des valves veineuses insuffisantes.
