Abstract
A cutting device is provided to cut stenosed aortic valve leaflets using a percutaneous approach. The device has a central catheter that moves over a guide wire to pass into a patient's aortic valve. Cutting wires are deployed from the catheter and have high speed rotating cutting surfaces that cut into the stenosed tissue. A plurality of guidewires outward from the cutting wires serve to center and position the cutter within the patient's aortic valve. In an alternative embodiment, a shield is deployed between the cutting wires and the patient's aortic valve to prevent the cutting wires from cutting into the aortic root or aortic sinus wall.
