Balloon Catheters and Methods for Treating Paranasal Sinuses
First Claim
1. A method of treating a narrowed or obstructed space in a patient'"'"'s nasal sinuses, comprising:
- providing a catheter device comprising an expandable and contractible member which is expandable from a first smaller contracted profile to a second larger expanded profile;
pushing said member while in said contracted profile into a narrowed or obstructed space associated with a nasal sinus of said patient; and
, expanding said member to said expanded profile, thereby dilating said space.

Abstract
A set of sinus balloon catheters are provided for treating a patient'"'"'s paranasal sinus system, including dilating prepared openings, and natural ostia and ducts and excising sinus cavities. These include a balloon catheter with a bend placing a distal segment at 90.degree. to a proximal segment and a balloon catheter which is substantially straight. 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, or sinus to be excised. The catheters have appropriate inflated working diameters and appropriate outer diameters with the balloon deflated that will enable the catheter to be pushed into the respective prepared opening, natural ostium or duct, or sinus cavity to be excised. 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, and/or to dilate sinus cavities to remove them.

20. A method of treating a narrowed or obstructed space in a patient'"'"'s nasal sinuses, comprising:
-
providing a catheter device comprising a balloon and an inflation/deflation supply conduit in fluid communication with said balloon;
pushing said balloon in a deflated condition into a narrowed or obstructed space associated with a nasal sinus of said patient; and
introducing fluid under pressure into said supply conduit to inflate said balloon and dilate said space.
