1. A method of securing a stent-graft prosthesis placed at a desired site in a passageway of a human body using a support member having first and second fasteners releasably coupled thereto comprising:

  • delivering a support member having releasably coupled thereto first and second fasteners, each having a proximal piercing end portion and a distal piercing end portion, to a site where a stent-graft prosthesis, which has a tubular wall, has been placed in the passageway, which has a wall;

    advancing the proximal piercing end portion of a first one of the first and second fasteners beyond the prosthesis;

    penetrating the proximal piercing end portion of said first one of the fasteners into the wall of the fasteners through the tubular wall of the prosthesis;

    passing the distal piercing end portion of said first one of the fastneners through the tubular wall of the prosthesis and into the wall of the passageway;

    deploying a second one of the first and second fasteners and attaching it to the passageway wall such that its proximal piercing end portion is penetrated into the wall of the passageway without passing through the tubular wall of the prosthesis and its distal piercing end portion is passed through the tubular wall of the prosthesis and into the wall of the passageway;

    wherein the piercing end portions of said first one of the fasteners are penetrated into the wall sequentially and the piercing end portions of said second one of the fasteners are penetrated into the wall sequentially; and

    withdrawing the support member and leaving the fasteners, which fix the prosthesis to the passageway wall, in the passageway wall.
