Filed:

Mar 13, 2013

Appl. No.:

13/800163

Inventors:

Jessica Liberatore - San Mateo CA, US
Sandra W. Ruggles - Sunnyvale CA, US
Jessica K. Chan - Sunnyvale CA, US

International Classification:

A61M 25/01
A61B 1/07
A61M 3/02

US Classification:

600431, 604275, 604514, 600156

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.
