Abstract
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 and 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, 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.
