Prosthetic valve delivery system
First Claim
1. A prosthetic valve delivery system comprising:
- a stented prosthetic valve havinga tubular stent assembly with a balloon-expandable stent portion attached to at least one self-expanding stent portion, anda prosthetic valve component disposed within and secured to the balloon-expandable stent portion of the stent assembly; and
a dual balloon catheter havinga first balloon on which the stented prosthetic valve is disposed in a delivery configuration, the first balloon having a first working diameter for expanding the balloon-expandable stent portion to a first diameter, anda second balloon having a second working diameter that is greater than the first working diameter of the first balloon for expanding the balloon-expandable stent portion to a second diameter greater than the first diameter.

Abstract
A prosthetic valve delivery system for percutaneously delivering and deploying a prosthetic valve within an existing valve is disclosed. The delivery system includes a stented prosthetic valve having a balloon-expandable stent portion with a prosthetic valve disposed therein and at least one self-expanding stent portion. The delivery system further includes a dual balloon catheter having a first balloon on which the stented prosthetic valve is disposed during delivery and a second balloon. Upon delivery within the existing valve, the self-expanding stent portion contacts the existing valve and the first balloon expands the balloon-expandable stent portion to a first diameter such that the stented prosthetic valve is in a first stage deployment configuration. The second balloon then expands the balloon-expandable stent portion to a second diameter, greater than the first diameter, such that the stented prosthetic valve is in a second stage deployment configuration being fully deployed within the existing valve.
