Patent ID: 7785364

Claim:
A kit to be implanted in a blood circulation conduit, said kit comprising: a tubular endoprosthesis having an inner surface configured to delimit a channel with a longitudinal axis; and a prosthetic valve to be implanted in said tubular endoprosthesis and movable relative to said tubular endoprosthesis, said prosthetic valve including: a supporting framework having an outer surface to be applied against said inner surface of said endoprosthesis, said framework being radially deformable from a folded fitting position to a deployed implantation position; and a flexible obturator connected to said framework, said obturator being deformable between a closure position in which said obturator extends transversely, and a release position in which said obturator contracts transversely due to a flow circulating through said channel; wherein said endoprosthesis includes a stop for locking said prosthetic valve in said channel to prevent axial displacement of said outer surface of said framework along said inner surface of said endoprosthesis in at least a first direction, said stop including a flexible connection extending transversely across said channel between two connection points located on said inner surface of said endoprosthesis and spaced angularly about said longitudinal axis of said channel.
