Abstract

Selon l'invention, ce dispositif (1) comprend: au moins un segment (7, 8) expansible radialement, présentant, à l'état expansé, une section transversale sensiblement supérieure à la section transversale de l'un des conduits secondaires (3); un segment (6) présentant, à l'état expansé, une forme tronconique, correspondant à la forme de la bifurcation au niveau de la zone de transition évasée (11) qui sépare le conduit principal (2) des conduits secondaires (3); et une liaison souple (9) entre ces deux segments (6, 7), permettant l'orientation de ceux-ci l'un par rapport à l'autre, selon l'orientation du conduit secondaire (3) recevant ledit segment (7) par rapport à ladite zone de transition évasée (11).
