Abstract
A system for percutaneously introducing a prosthetic valve into a patient's vasculature comprises a balloon dilatation catheter, a prosthetic valve mounted coaxial to the dilatation balloon, and a pusher member comprising a longitudinally extending tubular member encompassing the shaft of the catheter. The distal end of the pusher member preferably corresponds to the proximal end of the stent component of the prosthetic valve. The pusher member provides enhanced longitudinal pushability for facilitating advancement of the prosthetic valve to a treatment site. The system is well-suited for advancing a prosthetic valve or other medical device through an introducer sheath having a relatively small inner diameter. The introducer sheath may be formed with a tapered proximal end portion for receiving the prosthetic valve and for reducing a diameter of the prosthetic valve during advancement therethrough.
