TECHNICAL FIELD [0001] The field of this invention fluid delivery, particularly localized fluid delivery to a physiological site. BACKGROUND OF THE INVENTION [0002] There are many medical procedures currently practiced in which a fluid is administered to the subject being treated, where such procedures include drug delivery, imaging agent delivery, irrigation, etc. In many situations, it is desirable to provide for localized fluid delivery to a specific region or location (i.e., site) of the subject being treated. Such situations include those in which a toxic agent is being administered and it is desired to reduce the systemic toxicity of the agent; those in which an expensive agent is being administered and targeted delivery is sufficient for the intended purpose; and the like. [0003] A number of different localized fluid delivery devices have been developed for use in a variety of procedures. For example, numerous and diverse fluid delivery devices, e.g., catheter and non-catheter devices, that provide for localized fluid delivery to a particular site have been developed to be used in a variety of different applications. In many such embodiments, the fluid delivery devices are relatively complex in that they include various isolation elements for producing an isolated environment around the target site. While such devices can be effective, the isolated environment is typically much larger than the target site, resulting in contact of the fluid with unwanted areas adjacent to the target site. [0004] As such, there is a continued need for the development of additional fluid delivery devices for use in localized fluid delivery to a specific region, location or site of a subject. Of particular interest would be the development of such a device that was simple and provided for precise, highly localized delivery of fluid to a target site with minimal, if any, fluid contact to regions adjacent to the target site.

SUMMARY OF THE INVENTION [0006] 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. Both open-field surgical, e.g., "hand-held," and percutaneous devices, e.g., for use in intervential approaches, such as beating heart applications, are provided. 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. BRIEF DESCRIPTION OF THE FIGS.
