The present invention relates to a medical device, and in particular, to a stent-based valve (100). The valve includes a radially expandable structural frame (101) comprising a proximal anchor (103) and a distal anchor (104). The proximal and distal anchors are formed from a lattice of interconnected elements, and have a substantially cylindrical configuration with first and second open ends and a longitudinal axis extending there between. The stent based valve also comprises one or more connecting members (105), each having a first and a second end. The first end of each connecting member is attached to the proximal anchor and the second end of each connecting member is attached to the distal anchor. A biocompatible valve assembly (400) is attached to the proximal anchor and extends distally along the one or more connecting members.

La présente invention concerne un dispositif médical et, en particulier, une valve de type stent (100). Ladite valve présente une structure à expansion radiale (101) comprenant un dispositif d'ancrage proximal (103) et un dispositif d'ancrage distal (104). Les dispositifs d'ancrage proximal et distal sont formés à partir d'un réseau d'éléments interconnectés, et présentent une configuration sensiblement cylindrique avec une première et une seconde extrémité ouverte et un axe longitudinal s'étendant entre celles-ci. La valve de type stent comprend également un ou plusieurs éléments de connexion (105), présentant chacun une première et une seconde extrémité. La première extrémité de chaque élément de connexion est rattachée au dispositif d'ancrage proximal, et la seconde extrémité de chaque élément de connexion est rattachée au dispositif d'ancrage distal. Un ensemble valve biocompatible (400) est rattaché au dispositif d'ancrage proximal et s'étend radialement le long d'un ou de plusieurs élémennts de connexion.
