摘要：
The present invention provides a method to treat sinusitis comprising (a) inserting a portion of an irrigation catheter (100, 200) having an expandable material (e.g., 1 10, 212) in a non-expanded state endoscopically into a sinus (e.g., 2, 4, 6) of a patient through ostium (e.g., 138) of a sinus (2)； (b) expand the expandable material under endoscopic visualization until it has expanded and filled some portion of the sinus without directly contacting and compressing mucosal surfaces (144) of the sinus； (c) introducing irrigation fluid into the sinus through an irrigation lumen of the catheter to create a circumferential irrigation flow in space between the expanded material and the mucosal surface in order to dislodge and express sinus contents.
