The invention is relative to a stent (1) with a tublar 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 (11). The thread ends (12, 13) are guided via a deflection (14) from the outside into support frame (2), where they are coupled by a connector consisting of a material visible in x-rays. Deflection (14) is realized by two deflection elements (15, 16) in the form of eyelets provided on annular segment (3). Deflection elements (15, 16) are arranged on the circumference of support frame (2) at an interval from one another and are provided on end-side annular segment (3), viewed in longitudinal direction L of the stent.

L'invention concerne un stent (1) avec ossature tubulaire (2), composé de segments annulaires interconnectés successifs (3, 4, 5), la dite ossature étant entourée à l'extérieur d'un fil (11). Les extrémités du fil (12, 13) sont guidées par une déviation (14) de l'extérieur dans l'intérieur de l'ossature (2), où elles sont reliées par un raccord fait d'un matériau visible aux rayons X. La déviation (14) est obtenue au moyen de deux éléments de déviation (15, 16) du type oeillet sur le segment annulaire (3). Les éléments de déviation (15, 16) sont disposés à la périphérie de l'ossature (2) à l'écart l'un de l'autre, sur un segment annulaire latéral (3), vu dans le sens longitudinal L du stent.
