1. A device for providing a fluid to a target tissue region of a body vessel, the device comprising:
- an elongate member having a lumen extending longitudinally therethrough from an entry port near a proximal end and to at least one exit port near a distal end of the elongate member, the member being adapted to receive a fluid into the entry port so that the fluid exits the at least one exit port and into a region of the vessel near a target tissue region; and
a structure deployable from a distal portion of the elongate member, the deployable structure being adapted, when deployed, to channel blood flowing in the vessel and substantially isolate the blood flowing through the vessel from the region within the vessel near the target tissue region.
