  • Patent number: 8974510
    Abstract: The device includes at least a tubular endoprosthesis (6), deployable between a retracted state and a dilated state, and a hollow support (10) which extends longitudinally between a proximal end (18) and a distal end (16). The support (10) is provided, in the vicinity of the distal end (16), with at least a transverse retention opening. The device includes at least a releasable threadlike tie (12, 14) for holding the endoprosthesis (6) on the support (10).

  • Patent number: 8623072
    Abstract: A tubular prosthesis is radially deformable and includes a lattice that is deformable between a retracted state of small diameter and an expanded state of larger diameter. The prosthesis includes at least two outer hooks delimiting between them a clamp for engaging in an outer tissue. The two hooks are carried by the lattice and can be moved between a spaced-apart position in which the clamp is open and a closer-together position in which the clamp is closed. The prosthesis includes a guiding member for moving at least one of the hooks during deformation of the prosthesis. The guiding member delimits a guide passage in which at least one of the hooks is engaged.

  • Patent number: 8512396
    Abstract: This device (10) includes an implant (20) which has a tubular endoprosthesis (30) with a radially deployable framework (36). The implant (20) includes a flexible interposition member (24) mounted movably on the endoprosthesis (30) so as to be interposed between the outer surface (40) and a blood circulation conduit (14). The device (10) includes a deployment tool (26) which can adopt a configuration for insertion of the implant (20) and a configuration for release of the implant (20). In the configuration for insertion of the implant (20), the flexible member (24) includes at least one free part (68) held axially away from the outer surface (40) in order to minimize the radial dimension of the implant (20). The free part (68) is at least partly displaceable against the outer surface (40) when the tool (26) moves from its configuration for insertion to its configuration for release.

  • Patent number: 8252037
    Abstract: This device comprises a tubular endoprosthesis (11) of axis (X-X?) and a stent (13) of axis (Y-Y?) defining a distal retention opening (23A) and a proximal retention opening (23B). The device comprises a distal wire-like tie (33A) and a proximal wire-like tie (33B). Each tie (33A, 33B) forms a retaining loop (43) running around the endoprosthesis (11). Each retaining loop (43) can stretch between a configuration in which the endoprosthesis (11) is kept in a contracted state against the stent (13) and a configuration in which the endoprosthesis (11) is released. When each retaining loop (43) is in its releasing configuration, the axis (X-X?) of the endoprosthesis (11) is inclined with respect to the axis (Y-Y?) of the stent (13) when no external stresses are applied. The axis (X-X?) of the endoprosthesis (11) intersects the axis (Y-Y?) of the stent in the internal line (18) defined by the endoprosthesis (11).

  • Patent number: 8246675
    Abstract: A kit for implanting in a duct, which includes a tubular endoprosthesis and a prosthetic valve is disclosed. The prosthetic valve includes a carrier frame that is radially deformable in elastic manner relative to a central axis of the tubular endoprosthesis between a deployed, implanted position, and a folded, implanting position. The carrier frame is urged elastically towards its deployed position. A flexible shutter is connected to the carrier frame. The shutter is deformable between an obstruction position in which it is extended transversely, and a release position in which it is contracted transversely under to allow a fluid to flow through the carrier frame. The carrier frame also includes an integrated centripetal compressing mechanism for centripetally compressing the carrier frame towards folded position.

  • Patent number: 8202309
    Abstract: A kit includes an implantable treatment element (13) which can be radially deformed between a retracted state and a deployed state, and a sheath (15) for maintaining the treatment element (13) in its retracted state. The kit also includes a member (19) for pulling the treatment element (13) into the sheath (15), which includes a sleeve (17) for receiving the treatment element (13) which can slide in relation to the sheath (15) between an expanded position for receiving the treatment element (13) and a compressed interposed position between the treatment element (13) and the sheath (15). The treatment element (13) is substantially axially fixed in relation to the receiving sleeve (17) when the sleeve (17) moves between its receiving and interposed positions. The kit can be used to insert endoprostheses into a blood vessel.

  • Patent number: 8167934
    Abstract: This implant comprises an endoprosthesis having an axis which can be spontaneously deployed in a radial manner between a compressed configuration and a dilated configuration. The implant comprises at least one radial runner which comprises a separation surface which extends radially with respect to an outer surface of the endoprosthesis and a member which can be deployed away from the axis. The runner is arranged so as to delimit a confinement housing which extends between the separation surface and the outer surface and a radial spacer which is defined by the separation surface and the deployable member. When the implant is retained in a state of radial compression, the maximum radial width of the housing is less than the maximum radial width of the spacer which is not equal to zero.
