An apparatus for applying a spray to a selected site on a patient includes a sheath having a through bore extending from a first end to a second end. A flexible multi-lumen tube is secured within the sheath and has a distal portion that extends beyond the second end of the sheath. A malleable wire is positioned within at least the distal portion of the multi-lumen tube wherein manual force is exerted upon the distal portion to position the distal end in a selected position by bending the malleable wire. A housing is attached to the rigid outer sheath and has a plurality of ports for engaging a multi-tube syringe and a port for injecting a gas into the selected site wherein each port is in communication with at least one lumen. A spray nozzle is removably attached to the distal end of the multi-lumen tube wherein the at least one liquid and the gas are discharged from the multi-lumen tube and into the spray nozzle such that the aerosol exiting the spray nozzle is effective in treating the selected site.
