Balloon catheters and methods for treating paranasal sinuses
First Claim
1. A method of treating a patient'"'"'s nasal sinuses, comprising:
- (a) providing a balloon catheter having a tubular catheter body with a proximal segment, a distal segment, a balloon mounted around said distal segment, a slot through a wall of said distal segment, said tubular catheter body being closed at a point distally of said slot, and means for providing fluid under pressure at the proximal segment of said tubular catheter body to inflate said balloon;
(b) pushing said distal segment with said balloon deflated into a space associated with a nasal sinus of said patient, said tubular catheter body having sufficient stiffness and column strength to be pushed into said space; and
(c) introducing fluid under pressure through said proximal segment of said tubular catheter body to inflate said balloon and dilate 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° 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.
