Abstract

A system for manipulating a guide catheter within a patient's nasal passages or sinus cavities includes a guide catheter formed from an elongate flexible member having a lumen passing there through. A wire guide is slidably disposed within the lumen of the guide catheter. The system further includes a steering member fixedly secured to a proximal end of the wire guide and a proximal hub secured to a proximal end of the guide catheter. The system further includes a recessed handle having a first recess for fixedly receiving the proximal hub of the guide catheter and a second recess for receiving the steering member, the second recess being dimensioned to permit axial and rotational movement of the steering member while disposed in the second recess.

First claim

What is claimed is:

1. A system for manipulating a cannula within a patient's sinus cavity comprising:
a cannula having an exterior surface and including a lumen passing therethrough;
a piercing member slidably disposed in the lumen of the cannula and configured to form an artificial passageway through the canine fossa region and into a sinus cavity, the artificial passageway being dimensioned to receive both the cannula and the piercing member contained therein;
an adjustable stopping surface disposed on the exterior surface of the cannula at a distal portion of the cannula, the adjustable stopping surface secured to the exterior surface of the cannula by one or more tightening members;
a balloon dilation catheter slidably moveable within the lumen of the cannula, the balloon dilation catheter being configured to dilate a drainage passage in the sinus cavity; and
an endoscope configured for viewing the drainage passage.

2. The system of claim 1 , wherein the distal end of the cannula comprises a curved tip.

3. The system of claim 1 , wherein the curved tip of the cannula is formed after the cannula is introduced into the artificial passageway.

4. The system of claim 3 , wherein the curved tip is flexibly biased in a curved configuration.

5. The system of claim 1 , further comprising a stabilization device configured to stabilize the cannula within the artificial passageway.

6. A system for manipulating a cannula within a sinus cavity of a subject comprising:
a cannula having a proximal end and a distal end and a lumen passing therethrough;
a piercing member slidably disposed in the lumen of the cannula and configured to form an artificial opening in the canine fossa region of the subject and into the maxillary sinus cavity of the subject, the artificial opening being dimensioned to receive both the cannula and the piercing member; and
an adiustable stopping surface disposed on an exterior surface of the piercing member and located distal with respect to the distal end of the cannula, the adiustable stopping surface being secured to the exterior surface by one or more tightening members;
a balloon dilation catheter configured for passage through the lumen of the cannula and into the sinus cavity, the balloon dilation catheter comprising a dilation balloon configured to dilate a sinus ostium.

7. The system of claim 6 , wherein the curved portion of the cannula is formed after the cannula is placed into the artificial opening.

8. The system of claim 6 , further comprising a stabilization device configured to stabilize the cannula within the artificial opening.

9. The system of claim 1 , wherein the adjustable stopping surface is removable.

10. The system of claim 6 , wherein the adjustable stopping surface is removable.
