Abstract
An irrigation catheter for the treatment of the sinus anatomy is described. The catheter comprises a proximal portion, a rigid middle portion, and a flexible distal portion. The flexible distal portion comprises an irrigation tip and the proximal portion has a stiffness that is intermediate the stiffness of the rigid middle portion and the flexible distal portion. The irrigation tip has a tip opening and one or more radially facing openings. A method for irrigating or suctioning the sinus anatomy includes inserting an irrigation catheter into a patient's anatomy and irrigating or suctioning a target space.
