Balloon catheters and methods for treating paranasal sinuses
First Claim
1. A method of using a dilator to treat a patient, wherein the dilator comprises:
- (i) a first tubular elongate member body having a proximal segment and a distal segment,(ii) a balloon mounted located at the distal segment of the first tubular elongate member body, and(iii) a port located at the proximal segment of the first tubular elongate member body, wherein the port is configured to provide fluid under pressure to inflate the balloon;
wherein the method comprises;
(a) pushing the distal segment of the first tubular elongate member body via the proximal segment of the first tubular elongate member body to position the distal segment of the first tubular elongate member body into a space associated with a nasal sinus of the patient, wherein the balloon is in a deflated state during the act of pushing, the first tubular elongate member body having sufficient stiffness and column strength to be pushed into the space; and
(b) introducing fluid under pressure through the proximal segment of the first tubular elongate member body to inflate the balloon and dilate the 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.
