    摘要： An implantable prosthetic valve having a stentless support structure. The valve has a tubular annular support structure with a first inflatable ring at a proximal end, a second inflatable ring at a distal end, and an inflatable intermediate support in between the first and second inflatable rings. There is at least one moveable occluder that controls the flow of blood through the tubular support structure. The tubular support structure can be filled with inflation media in the first inflatable ring, the second inflatable ring and inflatable intermediate support structure to convert the tubular support structure from a collapsed configuration to a patent tubular configuration.

    摘要： A method of treating a patient with a calcified aortic valve includes introducing a guide wire into a blood vessel. The guide wire is advanced through the aorta to the aortic valve and then through the aortic valve. A balloon dilatation catheter is introduced into the blood vessel over the guide wire. The balloon dilatation catheter includes an elongate body, a distal portion, a guide wire lumen, an inflation lumen, and a dilatation balloon. The balloon dilatation catheter further includes at least one deflection wire lumen, the at least one deflection wire lumen having a distal opening proximal the distal portion, and at least one deflection wire residing in the at least one deflection wire lumen and having a distal end attached to the distal portion. The balloon dilatation catheter is advanced over the guide wire through the aorta. The deflection wire is pushed towards the distal portion so that the deflection wire bows outward. The balloon dilatation catheter is advanced through the aortic valve, and the dilatation balloon is inflated.
