1. A method of implanting a prosthetic heart valve, the method comprising the steps of:
- translumenally advancing a catheter carrying a prosthetic valve that comprises an inflatable cuff to a position proximate a native valve of a patient;
inflating a first chamber of the inflatable cuff within the left ventricle of the patient;
independently inflating a second chamber of the inflatable cuff within the aorta of the patient; and
removing the catheter from the patient, leaving the prosthetic valve and the inflated inflatable cuff within the patient;
wherein the prosthetic valve is functional prior to full inflation of the inflatable cuff.

Abstract
A method of implanting a prosthetic valve within the heart comprises translumenally advancing a prosthetic valve comprising an inflatable structure to a position proximate a native valve of the heart. A first chamber of the inflatable structure is inflated and then, independently, a second chamber of the inflatable structure is inflated.

19. A method of implanting a prosthetic heart valve, the method comprising the steps of:
-
translumenally advancing a catheter carrying a prosthetic valve that comprises an inflatable cuff permanently attached to a valve mechanism to a position proximate a native valve; inflating a first chamber of the inflatable cuff within the left ventricle; manipulating the position of the prosthetic valve using at least one control wire; independently inflating a second chamber of the inflatable cuff within the aorta; releasing the prosthetic valve from the control wire following the independently inflating the second chamber step; and removing the catheter, leaving the prosthetic valve; wherein the control wire comprises a tubular sheath and a core wire, and the step of releasing the prosthetic valve from the control wire comprises axially retracting the core wire with respect to the sheath. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
