Claim Text:
1. A catheter for delivering a prosthesis to a treatment site in a body lumen, the catheter comprising: an elongate flexible member having a proximal end and a distal end; a sheath slidably disposed over the elongate flexible member; a plurality of self-expanding tubular prostheses carried in axially spaced-apart locations along the elongate flexible member and within the sheath, the plurality of self-expanding tubular prostheses adapted to be selectively interlocked with one another and constrained by the sheath in a radially contracted configuration, the prostheses being separately releasable from the sheath as the sheath is retracted relative to the elongate flexible member; and a pusher member slidably disposed along the elongate flexible member within the sheath, the pusher member adapted to move past the prostheses in a first direction, while in a second direction the pusher member engages a selected prosthesis so as to move the prosthesis with the pusher member to interlock the selected prosthesis with a second prosthesis; wherein the pusher member has an engagement member which is deflectable radially inward by contact with the prostheses when moved in the first direction.
