Translumenally implantable heart valve with multiple chamber formed in place support
First Claim
1. A cardiovascular prosthetic valve, the valve comprising:
- an inflatable cuff comprising at least one inflatable channel that forms, at least in part, a distal inflatable toroidal structure and a proximal inflatable toroidal structure, the inflatable cuff also comprising a waist that extends between the distal inflatable toroidal structure and the proximal inflatable toroidal 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.

Abstract
A cardiovascular prosthetic valve comprises an inflatable body that has at least a first inflatable chamber and a second inflatable chamber that is not in fluid communication with the first inflatable chamber. The inflatable body is configured to form, at least in part, a generally annular ring. A valve is coupled to the inflatable body. The valve is configured to permit flow in a first axial direction and to inhibit flow in a second axial direction opposite to the first axial direction. A first inflation port is in communication with the first inflatable chamber. A second inflation port in communication with the second inflatable chamber.

3. A prosthetic valve for replacing an aortic valve positioned between the left ventricle and the aorta of the heart, the valve comprising:
-
an inflatable structure comprising a distal end and a proximal end; and
a valve member coupled to the inflatable structure, the valve member being positioned generally between the distal and proximal ends of the inflatable structure;
wherein the distal end of the inflatable structure is configured to be positioned within the left ventricle and the proximal end of the inflatable structure is configured to be positioned within the aorta. - View Dependent Claims (4)
