Abstract

La présente invention concerne un stent ramifié (1) composé d'un matériau de départ en forme de brin, en particulier en forme de fils et/ou de filaments (9), comprenant un bras principal (2) qui présente une lumière principale (4) sensiblement tubulaire et un bras latéral (3) bifurquant du bras principal (2), le bras latéral (3) pouvant passer d'un premier état, dans lequel le bras latéral (3) se situe au moins partiellement, de préférence entièrement, à l'intérieur de la lumière principale (4), à un second état dans lequel le bras latéral (3) se situe à l'extérieur de la lumière principale (4), le bras latéral (3) présentant, dans le second état, une lumière latérale (6) sensiblement tubulaire qui est en communication fluidique avec la lumière principale (4). Selon l'invention, le bras latéral (3) comprend un matériau à mémoire de forme. L'invention concerne en outre un système de stent (8) comprenant un stent ramifié (1) selon la description ci-dessus et un stent latéral (7), le stent ramifié (1) présentant un bras principal (2) et un bras latéral (3) et le diamètre d'une extrémité du stent latéral (7) étant à peu près égal au diamètre de l'extrémité du bras latéral (3) opposée au bras principal (2).
