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.
