1. A prosthesis retaining assembly for securing an implantable prosthesis to a catheter assembly, the prosthesis retaining assembly comprising:

  • a first member including,a central longitudinal axis,a central lumen,a first end surface,a longitudinal passage radially offset from the central lumen, the longitudinal passage extending to the first end surface,a prosthesis retaining slot configured to retain a portion of the prosthesis, the retaining slot being configured to retain a portion of the prosthesis such that when the portion of the prosthesis is retained within the retaining slot longitudinal movement of the prosthesis relative to the first member is prevented, the retaining slot having an inner opening intersecting with the longitudinal passage and an outer opening intersecting with an outer surface of the first member; and

    a second member positioned within the longitudinal passage of the first member, the second member being movable relative to the first member betweena first position at which a portion of the second member is positioned adjacent to and obstructs a portion of the inner opening of the retaining slot preventing the portion of the prosthesis retained within the retaining slot from exiting the inner opening of the retaining slot in a radially inward direction towards the central longitudinal axis, anda second position at which the portion of the second member is moved relative to the retaining slot such that the portion of the prosthesis can pass through the inner opening of the retaining slot in a radially outward direction away from the central longitudinal axis.
