Localized fluid delivery having a porous applicator and methods for using the same
First Claim
Patent Images
1. 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.

Abstract
Fluid delivery devices having a porous applicator, as well as methods for using the same in the highly localized delivery of fluid to a target site, are provided. The subject devices have a porous applicator through which fluid must flow in order to contact the target delivery site. The subject devices find use in a variety of fluid delivery applications in which the localized delivery of a fluid to a target site is desired. Also provided are systems and kits that include the subject fluid delivery devices.
