Description

A stent and a method for fabricating the stent are disclosed. The stent has an originally flat pattern and connection points where the sides of the flat pattern are joined. The method includes the steps of a) cutting a stent pattern into a flat piece of metal thereby to produce a metal pattern, b) deforming the metal pattern so as to cause two opposing sides to meet, and c) joining the two opposing sides at least at one point. Substantially no portion of the stent projects into the lumen of the stent when the stent is expanded against the internal wall of a blood vessel.

Divulgation d'une endoprothèse vasculaire et d'une méthode pour sa fabrication. Au départ, l'endoprothèse vasculaire a un profil plat et des points de jonction là où les côtés du profil plat se rejoignent. Ladite méthode comprend les étapes suivantes : a) découpage dans un morceau plat de métal d'un profil d'endoprothèse vasculaire pour produire un profil métallique, b) déformation du profil métallique de manière à ce que les deux faces opposées soient jointes, c) réunion des deux faces opposées en au moins un point. Essentiellement aucune partie de l'endoprothèse vasculaire ne se projette dans la lumière qu'elle forme lorsque l'endoprothèse vasculaire est élargie pour s'appuyer sur la paroi interne d'un vaisseau sanguin.
