Multi-conduit balloon catheter
First Claim
1. A method of treating a patient'"'"'s nasal sinuses, comprising:
- (a) providing a balloon catheter having an oblong body having a proximal segment, a balloon member including a distal terminal end, a distal segment, an inflation/deflation supply conduit in fluid communication with a balloon mounted on said distal segment, an irrigation conduit extending distally from said balloon, a suction conduit extending distally from said irrigation conduit, the irrigation conduit configured about and coaxial with the suction conduit, the inflation/deflation supply conduit positioned outside an outer diameter of the irrigation conduit, and a balloon catheter terminal end defining a suction opening which is outside and extending distally beyond the distal terminal end of the balloon;
(b) pushing said distal segment with said balloon deflated into a space associated with a nasal sinus of said patient;
(c) introducing fluid under pressure into said inflation/deflation supply conduit to inflate said balloon and dilate said space;
(d) introducing fluid via said irrigation conduit distally of said balloon, and(e) configuring the terminal end to suction material at a treatment site distally of said balloon via said suction conduit.

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.

8. A catheter for dilating a space in a patient, said catheter comprising:
-
(a) an oblong body having a proximal segment and a distal segment; (b) a balloon member secured to said distal segment and including a distal terminal end; (c) an inflation conduit in fluid communication with said balloon, wherein the inflation conduit comprises an interior surface and an exterior surface, whereby fluid under a given pressure in said inflation conduit inflates said balloon; (d) a suction conduit having a first distal port outside and extending distally beyond the distal terminal end of said balloon, wherein the suction conduit comprises an interior surface and an exterior surface; (e) an irrigation conduit having a second distal port outside said balloon, wherein the irrigation conduit comprises an interior surface and an exterior surface, wherein the exterior surface of the inflation conduit is positioned adjacent to the exterior surface of the irrigation conduit; and (f) a catheter distal terminal end defining a suction opening, wherein the irrigation conduit is configured about and coaxial with the suction conduit, and wherein the inflation conduit is positioned outside an outer diameter of the irrigation conduit. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A catheter for dilating a space in a patient, said catheter comprising:
-
(a) an oblong body having a proximal segment and a distal segment; (b) a balloon member secured to said distal segment and including a distal terminal end; (c) a first tube in fluid communication with said balloon, wherein the first tube has an outer diameter, whereby fluid under a given pressure in said first tube inflates said balloon; (d) a second tube having a first distal port outside and extending distally beyond the distal terminal end of said balloon, wherein the second tube has an outer diameter; (e) a third tube having a second distal port outside said balloon, wherein the third tube has an outer diameter, wherein the outer diameter of the first tube is positioned adjacent the outer diameter of the third tube; and (f) a catheter distal terminal end defining a suction opening, wherein the third tube is configured about and coaxial with the second tube, and wherein the outer diameter of the first tube is positioned outside the outer diameter of the second tube and outside the outer diameter of the third tube.
