Abstract
A prosthesis retaining assembly for securing an implantable prosthesis to a catheter assembly can include a first member including a prosthesis retaining slot configured to retain a portion of the prosthesis. The retaining slot can have a first portion with a first width and a second portion with a second width. The first portion can be distal to the second portion. The second width can be larger than the first width, and the retaining slot can have an opening at a first surface of the first member. The prosthesis retaining assembly can also include a second member configured to be move relative to the first member. The second member can be configured to move to a position that obstructs a portion of the opening of the retaining slot.

26. A prosthesis retaining assembly for securing an implantable prosthesis to a catheter assembly, the prosthesis retaining assembly comprising:
-
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 between a 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, and a 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. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A method of coupling a prosthesis to a catheter assembly, the catheter assembly including a valve retainer disposed at a distal portion of the catheter assembly, the valve retainer comprising a first member defining a retaining slot, the retaining slot having an inner opening intersecting with a longitudinal passage of the first member radially offset from a central lumen of the first member, and an outer opening intersecting with an outer surface of the first member, the method comprising:
-
inserting a portion of the prosthesis into a first opening at a first end of the longitudinal passage; applying pressure to the portion of the prosthesis to move a second member disposed in the longitudinal passage in a longitudinal direction away from the first opening until the second member does not block the inner opening of the retaining slot; and aligning the portion of the prosthesis with the inner opening of the retaining slot such that the portion of the prosthesis expands through the inner opening into the retaining slot. - View Dependent Claims (40, 41, 42)

43. A method of coupling a prosthesis to a catheter assembly and deploying the prosthesis at a target site, the catheter assembly including a valve retainer disposed at a distal portion of the catheter assembly, the valve retainer comprising a first member defining a retaining slot, the retaining slot having an inner opening intersecting with a longitudinal passage of the first member radially offset from a central lumen of the first member, and an outer opening intersecting with an outer surface of the first member, the method comprising:
-
covering the outer opening of the retaining slot with an outer tube; inserting a portion of the prosthesis into a first opening at a first end of the longitudinal passage; applying pressure to the portion of the prosthesis to move a second member disposed in the longitudinal passage in a longitudinal direction away from the first opening until the second member does not block the inner opening of the retaining slot; aligning the portion of the prosthesis with the inner opening of the retaining slot such that the portion of the prosthesis expands through the inner opening into the retaining slot, wherein the portion of the prosthesis is prevent from exiting the outer opening of the retaining slot by the outer tube; advancing the outer tube distally and radially compressing the prosthesis such that the prosthesis is disposed within the outer tube in a radially compressed configuration; delivering the catheter assembly to a target site within the vasculature of a patient; and deploying the prosthesis from the catheter assembly. - View Dependent Claims (44, 45)
