Abstract:
1. A method, the method comprising the steps of: providing an apparatus for reducing recoil of a prosthetic valve after it has been crimped on to a balloon member, the apparatus comprising: permitting blood flow in a first direction and substantially resisting flow in a second direction; crimping the prosthetic valve onto the balloon catheter using the crimper to provide a partially crimped prosthetic valve; advancing the distal end portion of the tube over the partially crimped prosthetic valve; crimping the partially crimped prosthetic valve and distal end portion of the tube using the crimper to provide the crimped prosthetic valve; advancing the compressing member over the distal end portion of the tube and crimped prosthetic valve; delivering the crimped prosthetic valve to a location within a native aortic valve of a patient while the crimped prosthetic valve is surrounded by the tube and compressing member; retracting the compressing member relative to the tube for allowing the distal end portion of the tube to flare outwardly; advancing the balloon catheter relative to the tube for advancing the crimped prosthetic valve out of the tube; and inflating the balloon member for expanding the crimped prosthetic valve within the native valve of the patient.
