Abstract
A medical device, and a system and packaged kit containing the medical device for the treatment of a sinus opening is described. The medical device comprises a proximal end, a distal end, and a shaft system having an inflation lumen and an irrigation lumen the proximal and. The shaft system has a proximal shaft section and a distal shaft section. An inflatable balloon is attached to the distal shaft section in a position that is proximal to said distal end. The irrigation tip is distal to the balloon on the distal shaft section and has a tip opening and one or more radially facing openings. A method for treating a sinus opening includes inserting a system that includes the medical device, a sinus guide catheter and a sinus guide element into a patient's anatomy, dilating the sinus opening and irrigating a target in the nasal anatomy.
