Abstract

L'invention concerne un implant de soutien (11), destiné à soutenir un élément corporel tubulaire, notamment une endoprothèse vasculaire destinée au soutien d'un vaisseau. L'implant de soutien comporte un élément (17) hélicoïdal enroulé autour d'un axe virtuel et se présentant sous forme de bande (12) dont la largeur est supérieure à l'épaisseur et qui est enroulée pour former un élément bande hélicoïdal (17). La largeur de la bande (12) est orientée dans le sens de l'axe et son épaisseur est perpendiculaire au sens de l'axe. La bande (12) est conçue de manière fonctionnelle comme un ressort et elle présente une perforation (13) dont les orifices la traversent dans le sens de son épaisseur, les orifices pouvant comporter des dépôts pour agents actifs. L'élément bande hélicoïdal (17) présente l'avantage d'avoir des sections (15a,15b) enroulées en sens inverses les unes par rapport aux autres. De manière particulièrement avantageuse, ledit implant de soutien possède un tulle interne (40) et un tulle externe (41) et les spirales superposées sont enroulées en sens inverses, cet implant étant alors un double élément bande hélicoïdal.
