Abstract

A lavage catheter for the treatment of a maxillary sinus is described. The catheter comprises a proximal portion and a distal portion. The distal portion comprises an irrigation tip. The irrigation tip has a tip opening through which fluid may be delivered by one handed operation of the catheter. A method for lavaging the maxillary sinus includes inserting the lavage catheter into a patient's anatomy and advancing the irrigation tip into the maxillary sinus using one hand.

Description

FIELD OF THE INVENTION

[0001] The present invention relates, in general, to medical devices and, in particular, to medical devices and related methods for the treatment of sinus conditions.BACKGROUND OF THE INVENTION

[0002] The paranasal sinuses are hollow cavities in the skull connected by small openings, known as ostia, to the nasal canal. Each ostium between a paranasal sinus and the nasal cavity is formed by a bone covered by a layer of mucosal tissue. Normally, air passes into and out of the paranasal sinuses through the ostia. Also, mucus is continually formed by the mucosal lining of the sinuses and drains through the ostia and into the nasal canal.

[0003] Sinusitis is a general term that refers to inflammation in one or more of the paranasal sinuses. Acute sinusitis can be associated with upper respiratory infections or allergic conditions, which may cause tissue swelling and temporarily impede normal trans-ostial drainage and ventilation of the sinuses, thereby resulting in som...
