Abstract:
1. A method of treating a patient's paranasal sinus having an obstructed or narrowed naturally occurring bony and mucosal ostium or duct which does not have scar tissue or granulation tissue, the method comprising: pushing a distal segment of a balloon catheter through the obstructed or narrowed naturally occurring bony and mucosal ostium or duct which does not have scar tissue or granulation tissue; inflating a balloon of the balloon catheter in the obstructed or narrowed naturally occurring bony and mucosal ostium or duct which does not have scar tissue or granulation tissue to enlarge the naturally occurring bony and mucosal ostium or duct, the bony and mucosal ostium or duct being enlarged when the balloon is inflated; and removing the balloon catheter from the now enlarged ostium or duct, which remains enlarged for a period of time effective to treat the obstructed ostium after the balloon catheter is removed.
