A vascular implant for replacing a native heart valve comprises a self expanding stent supporting a valve body having leaflets. The stent preferably comprises an anchoring structure configured to prevent the implant from passing through the valve annulus. For delivery, the implant is compacted within a delivery device and secured at one end. During delivery the implant is partially released from the delivery device, and positioning of the implant is verified prior to full release. The implant can be at least partially resheathed and repositioned if desired.

La présente invention concerne un implant vasculaire destiné à remplacer une valve cardiaque naturelle et comprenant une endoprothèse auto-expansible supportant un corps de valve comportant des valvules. L'endoprothèse comprend, de préférence, une structure d'ancrage conçue pour empêcher l'implant de passer à travers l'anneau valvulaire. Pour l'introduction, l'implant est compacté à l'intérieur d'un dispositif d'introduction et fixé à une extrémité. Durant l'introduction, l'implant est partiellement libéré du dispositif d'introduction et son positionnement est vérifié avant libération complète. L'implant peut être au moins partiellement replacé dans son dispositif d'introduction et repositionné si nécessaire.
