First Claim
Patent Images
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 support structure to a position proximate a native valve of a patient, wherein the inflatable support structure comprises at least two valves positioned at ends of the inflatable support structure;
inflating a first chamber of the inflatable support structure with a contrast media wherein a directional valve is located between the at least two valves positioned at ends of the inflatable support structure, and wherein the directional valve is configured to inflate the first chamber in a first axial direction and to inhibit flow in a second axial direction opposite to the first axial direction;
visualizing the prosthetic valve under fluoroscopy;
displacing the contrast media in the first chamber of the inflatable support structure with a new inflation media, and wherein the directional valve is configured to displace the contrast media in the first chamber with the new inflation media in the first axial direction and to inhibit flow in the second axial direction opposite to the first axial direction; and
removing the catheter from the patient, leaving the prosthetic valve and the inflated first chamber of the inflatable support structure within the patient.

Abstract
A cardiovascular prosthetic valve, the valve comprising an inflatable cuff comprising at least one inflatable channel that forms, at least in part, an inflatable structure, and a valve coupled to the inflatable cuff, the valve configured to permit flow in a first axial direction and to inhibit flow in a second axial direction opposite to the first axial direction, the valve comprising a plurality of tissue supports that extend generally in the axial direction and that are flexible and/or movable throughout a range in a radial direction.
