Abstract

Stents endoluminaux constitués d'un alliage à mémoire de forme, à auto-expansion élastique, qui sont au moins partiellement encapsulés dans une enveloppe en polytétrafluoroéthylène expansé (PTFEe) sensiblement monolithique. Un stent endoluminal, ayant un diamètre réduit lors de son introduction dans la lumière vasculaire et un diamètre final in vivo plus important, est encapsulé dans une enveloppe en PTFEe, qui recouvre circonférentiellement aussi bien sa paroi luminale que sa paroi abluminale sur au moins une partie de sa longueur. Ce stent endoluminal à mémoire de forme est constitué d'un alliage à mémoire de forme possédant soit une mémoire de forme, soit des propriétés pseudo-élastiques, ou bien d'un matériau élastique possédant une tension de ressort propre.
