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.

21. A device for locally contacting an aortic valve with a fluid, said device comprising:
-
(a) a fluid delivery lumen having a proximal end and a distal end;
(b) an aspiration lumen; and
(c) a porous fluid flow path configured to fit inside of an aortic sinus of said aortic valve and located at said distal end of said fluid delivery lumen such that fluid must flow through said porous fluid flow path to contact said aortic valve, wherein fluid is drawn through said porous fluid flow path by said aspiration lumen. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
