Abstract: To deliver a medication and its active ingredients to the esophagus, a nasal irrigator, which is capable of delivering medicated fluid that coats the whole nasal and paranasal sinus cavities, is used. The nasal irrigator forces an aerosol mist of the medicated fluid into the nasal cavity above the inferior turbinate, independent of a user's breathing in. Mucociliary clearance from the nasal cavity then delivers the medication to the throat and it is then topically introduced onto the esophagus over an extended period of time.

Abstract: The present invention provides a method and device for irrigation and topical delivery of materials within body lumens accessible by natural orifices. The device includes a catheter body containing a delivery lumen for transporting material and is pre-shapeable at room temperature. A connector such as a luer lock connector is located at the proximal end of the catheter body for connecting the device to a reservoir, and a tip with axial and/or radial exit holes is located at the distal end of the catheter body for insertion into body lumen. The tip is larger in diameter than the catheter body, thereby diffusing insertion pressure across a wider area, thus minimizing abrasion, contusion and accidental puncture of body tissue. The proximal end of the tip is tapered to the diameter of the catheter body to allow withdrawal of the tip without causing tissue trauma.
