Patent ID: 7815596

Claim:
A device for locally contacting aortic valve leaflets with a demineralization fluid, the device comprising: a central shaft; three distinct fluid contact elements arranged around the central shaft, each fluid contacting element comprising a porous applicator affixed to an impermeable backing, wherein the impermeable backing is located only at proximal end of the porous applicator; the distal ends of the fluid contacting elements being configured to fit snugly inside of the aortic sinus; fluid delivery elements for delivering a demineralization fluid from a source to the porous applicators; a shunt positioned within the central shaft and concentrically mounted therein for providing blood flow from the ventricle; an aspiration lumen formed from a gap between the shunt and the central shaft; and a valve occluder mounted to the central shaft, the valve occluder being configured to sit flush with the ventricular side of the aortic valve leaflets.
