The present invention relates to a medical device, and in particular, to a stent-based valve. The valve has a radially expandable structural frame (101) having a substantially cylindrical configuration with first (401) and second (402) open ends and a longitudinal axis (106) extending there between. The structural frame is formed from a lattice of interconnected elements and has a plurality of distal crowns (205). A biocompatible membrane (400) assembly maintaining a substantially cylindrical shape about the longitudinal axis is attached to the structural frame such that the structural frame supports the biocompatible membrane assembly in a slack condition between the distal crowns.
L'invention porte sur un dispositif médical, plus particulièrement sur une vanne à endoprothèse. Cette vanne possède une structure à expansion radiale (101) présentant une configuration sensiblement cylindrique avec une première (401) et seconde (402) extrémité ouverte et un axe longitudinal (106) qui s'étend entre les deux. La structure est formée d'un réseau d'éléments interconnectés et possède une pluralité de couronnes distales (205). Une membrane biocompatible (400) maintenant une forme sensiblement cylindrique autour de l'axe longitudinal est fixée à la structure de manière que cette dernière soutienne la membrane biocompatible dans un état tendu entre les couronnes distales.
