Implant which is intended to be placed in a blood vessel
First Claim
1. Implant which is intended to be placed in a blood vessel, of the type comprising:
- an endoprosthesis which has a longitudinal axis and which can be deployed spontaneously in a radial manner from a compressed configuration to a dilated configuration, the endoprosthesis delimiting an inner passage for blood flow and an outer peripheral surface;
at least one runner for radial support which co-operates with the endoprosthesis, the runner comprising a separation surface which extends radially with respect to the outer surface and at least one member which can be deployed away from the longitudinal axis relative to the separation surface;
wherein 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 formed by the separation surface and the deployable member;
and wherein, when the implant is retained in a state of radial compression around the or each runner, with the endoprosthesis being in the dilated configuration thereof, the maximum radial width of the housing is less than the maximum radial width of the spacer, the spacer having a maximum radial width which is not equal to zero.

Abstract
This implant (10) comprises an endoprosthesis (30) having an axis (X-X′) which can be spontaneously deployed in a radial manner between a compressed configuration and a dilated configuration. The implant (10) comprises at least one radial runner (28) which comprises a separation surface (60) which extends radially with respect to an outer surface (42) of the endoprosthesis and a member (54) which can be deployed away from the axis (X-X′).
The runner (28) is arranged so as to delimit a confinement housing (62) which extends between the separation surface (60) and the outer surface (42) and a radial spacer (65) which is defined by the separation surface (60) and the deployable member (54).
When the implant (10) is retained in a state of radial compression, the maximum radial width of the housing (62) is less than the maximum radial width of the spacer (65) which is not equal to zero.
Use in replacement of natural valves with endovalves.
