Abstract:
1. Apparatus for delivering a prosthesis into a target vessel of a patient, comprising: a flexible catheter having proximal and distal ends, said catheter comprising an outer sheath, a pusher shaft, and an inner shaft; an expandable member coupled to the inner shaft; a plurality of tubular prostheses releasably carried over the expandable member, the outer sheath disposed over the prostheses and being axially movable relative thereto, a distal end of the pusher shaft abutting a proximal end of one of the tubular prostheses; and a garage member at the distal end of the outer sheath having sufficient radial strength to constrain a proximal portion of the expandable member within the garage member from expansion when a distal portion of the expandable member outside the garage member is expanded to deploy one of the tubular prostheses, the garage member having a length at least as long as one of the tubular prostheses.
