METHOD AND APPARATUS FOR REPLACING A PROSTHETIC VALVE
First Claim
1. A method of percutaneously implanting a replacement prosthetic valve at a site occupied by a previously implanted prosthetic valve, the method comprising:
- positioning a stent within the previously implanted valve;
deploying the stent to cause the stent to become anchored to the previously implanted valve;
positioning the replacement valve within the deployed stent; and
deploying the replacement valve to cause the replacement valve to become anchored to the stent.

Abstract
In one aspect, the present disclosure concerns a percutaneously delivered adapter stent that is deployed within a previously implanted prosthetic valve and serves as an anchor or platform for implanting a percutaneously delivered replacement valve within the previously implanted valve. The adapter stent can be delivered to the implantation site via the patient'"'"'s vasculature and positioned within the previously implanted valve. The stent can then be deployed to cause the stent to expand and become anchored to the inner surface of the previously implanted valve. Subsequently, the replacement valve can be positioned within the adapter stent and deployed to cause the replacement valve to expand and become anchored to the adapter stent. The adapter stent and the replacement valve can be mounted on the same catheter for delivery to the implantation site.

12. A method of percutaneously implanting a replacement prosthetic valve in a patient at a site occupied by a previously implanted prosthetic valve, the method comprising:
-
advancing a catheter carrying a stent through the patient'"'"'s vasculature to position the stent within the previously implanted valve, the catheter also carrying the replacement valve; deploying the stent to cause the stent to become anchored to the previously implanted valve; re-positioning the catheter to position the replacement valve within the deployed stent; and deploying the replacement valve to cause the replacement valve to become anchored to the stent. - View Dependent Claims (13, 14)

15. An assembly for percutaneous replacement of a previously implanted prosthetic valve without removal of the previously implanted valve, the assembly comprising:
-
an adapter stent comprising a frame and an annular sealing member, the adapter stent being adapted to be deployed within the previously implanted valve; and a percutaneous, replacement prosthetic valve comprising a frame and a flexible valve member, the valve being adapted to be deployed within the deployed stent such that the sealing member provides a seal between the previously implanted valve and the replacement valve. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. An assembly for percutaneous replacement of a previously implanted prosthetic valve without removal of the previously implanted valve, comprising;
-
a replacement prosthetic valve having a frame and a flexible valve member, the replacement prosthetic valve being radially expandable and collapsible; and means for anchoring and sealing the replacement valve to the previously implanted valve, said means being separately deployable within the previously implanted valve prior to deploying the replacement valve within said means. - View Dependent Claims (25)
