Abstract: A device includes an expandable implant and a hollow stent internally defining a central passage. The hollow stent defines a retention opening of the implant near the distal end thereof. The inventive device also includes a wire-type link for releasably fixing the implant to the stent, which has a traction section introduced into the opening and extending inside the central passage.

The insulation channel receives only one wire-type link and defines a channel which is devoid of a link at least between the proximal end of the stent and the retention opening and is placed in the central channel.

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).

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.
