CA 2540372

The invention is relative to a stent (1) with a tubular support frame (2) consisting of axially successively following, interconnected annular segments (3, 4, 5) which support frame (2) is surrounded on its outside by a thread. The thread ends are guided via a deflection from the outside into support frame (2), where they are coupled by a connector consisting of a material visible in x-rays. Deflection is realized by two deflection elements (24, 25) in the form of eyelets provided on annular segments (3, 6). Deflection elements (24, 25) are arranged on the circumference of support frame (2) at an interval from one another and are provided on end-side annular segments (3, 6), viewed in longitudinal direction (L) of the stent (1).

La présente invention concerne un stent (1) pourvu d'un bâti support tubulaire (2) fait de segments annulaires (3, 4, 5) reliés les uns aux autres en un assemblage axial, lequel bâti support (2) étant entouré sur son extérieur par un fil (11). Les extrémités du fil (12, 13) sont guidées via une déflexion (14) partant de l'extérieur et pénétrant dans le bâti support (2), où elles sont couplées par un connecteur fait en un matériau visible aux rayons X. La déflexion (14) est réalisée par deux éléments de déflexion (15, 16) sous forme d'oeillets réalisés sur le segment annulaire. Ces éléments de déflexion (15, 16), qui sont agencés sur le pourtour du bâti support (2) à intervalles réguliers les uns des autres, équipent le segment annulaire d'extrémité (3) observé selon l'axe longitudinal (L) du stent.
