Abstract
A suctioning and irrigating sinus balloon catheter (301) is provided for treating a patient's paranasal sinus system, including dilating prepared openings, and natural ostia and ducts and excising sinus cavities and choana. The catheter has a number of fluid carrying conduits (320,321,322) to provide irrigation, suction and inflation/deflation to the distally mounted balloon (307). The catheters have sufficient stiffness and column strength that the balloon carrying distal segment of the catheter can be pushed into the prepared opening, natural ostium or duct, choana or sinus to be excised. Some catheters can be hand bendable by the surgeon. Some catheters provide the capability of threading an endoscope through one of the conduits. The methods use the balloon catheters to dilate prepared openings to selected parts of the sinus system, to dilate natural ostia and ducts of the sinus system, choana, and/or to dilate sinus cavities to remove them.
