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.

Claims

1. A catheter for dilating a space in a patient, said catheter comprises:

an oblong body having a proximal segment and a distal segment;

a balloon member secured to said distal segment;

a first conduit in fluid communication with said balloon, whereby fluid under a given pressure in said first conduit inflates said balloon; and

,

a second conduit having a distal port outside said balloon.

2. The catheter of claim 1, which further comprises said conduit being adapted to provide suction at said port.

3. The catheter of claim 1, which further comprises said conduit being adapted to provide irrigation at said port.

4. The catheter of claim 1, wherein said first and second conduits are formed into a multichannel fluid buss extending between said proximal and distal segments.

7. The catheter of claim 1, wherein said second conduit has a distal terminus at said port and wherein said port is located a first distance from a distal neck of said balloon.

8. The catheter of claim 1, wherein said balloon annularly surrounds a portion of said second conduit.

9. The catheter of claim 1, which further comprises a third conduit having a distal port outside said balloon.

10. The catheter of claim 9, wherein said second conduit and said third conduit are coaxial.

11. The catheter of claim 9, wherein said second conduit and said third conduit are non-coaxial.

16. The catheter of claim 1, wherein said body further comprises axial gradation markings.

17. The catheter of claim 1, wherein said second conduit has an inner diameter selected to allow passage of an endoscope therethrough.

29. In a sinus balloon catheter device comprising proximal and distal sections, a balloon mounted to said distal section, and a first conduit for inflating said balloon, an improvement which comprises a second conduit having a distal port outside said balloon.

30. (canceled)

31. A method of treating a patient'"'"'s nasal sinuses, comprising:

providing a balloon catheter having an oblong body having a proximal segment, a distal segment, and a first inflation/deflation supply conduit in fluid communication with a balloon mounted on said distal segment;

pushing said distal segment with said balloon deflated into a 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.

32. The method of claim 31, wherein said balloon catheter further comprises a second conduit.

33. The method of claim 32, which further comprises suctioning debris from said nasal sinus through said second conduit.

34. The method of claim 32, which further comprises irrigating said nasal sinus through said second conduit.

35. The method of claim 33, which further comprises irrigating said nasal sinus through said second conduit at a time when said suctioning is not occurring.

37. The method of claim 32, which further comprises inserting an endoscope through said second conduit.

38. The method of claim 32, wherein said balloon catheter further comprises a third conduit, and wherein said method further comprises:

suctioning debris from said nasal sinus through said second conduit; and

, irrigating said nasal sinus through said third conduit.

39. The method of claim 31, wherein said body is flexible, and said method further comprises threading said body onto a rigidizing member having sufficient stiffness and column strength to enable said catheter, when said balloon is deflated, to be pushed into said space of said nasal sinus system.
