Abstract: A blood vessel treatment device (10) includes a tubular implant (20) tending to expand radially; an introduction sleeve; a retaining guard (24); and a device (26) for releasably assembling the implant and the stent in an assembled configuration. The assembling device comprises a first (60) and a second (62) assembling members, held by the guard and by the implant respectively, said assembling members being able to be joined by translation in a transverse direction, so as to block relative movement of the implant and the guard. The assembling device further comprises a locking component (74) capable of longitudinal movement relative to the guard, such that in a locking position the locking component holds the first and second assembling members together.

Abstract: A tubular endoprosthesis (10) having a flexible tubular skirt (12) designed to channel a body fluid. The endoprosthesis includes a collar (14) for connection of the skirt (12) through a lateral wall (110) of a tubular conduit (108). The connection collar (14) is initially joined to one end of the skirt (12) and has, at its periphery, elements (34) for securing it to the wall (110). The securing elements (34) are deformable between an initial docking position and a final connection position.
