Abstract

A method of treating a constricted sinus passageway of a patient includes traversing the canine fossa region of the patient so as to form a passageway in the sinus cavity. An elongate member is inserted through the passageway, the elongate member having an inflation member such as a balloon disposed thereon. The inflation member is positioned within the constricted passageway. The inflation member is expanded so as to expand at least a portion of the constricted sinus passageway.

Claims

1. A method of dilating tissue of a drainage pathway of a sinus cavity of a patient, comprising:

directing a wire guide through a nasal passage and into the sinus cavity of the patient, wherein the wire guide extends through a guide catheter and wherein a proximal end of the guide catheter is secured to a distal end of a handle, and wherein the wire guide extends through a steering device, and wherein the handle defines a recess that opens along a longitudinal length of a side surface of the handle, and wherein directing the distal tip of the wire guide includes sliding the steering device along the recess in a direction parallel to a major longitudinal axis of the handle, and wherein directing the distal tip of the wire guide includes rotating the wire guide relative to the handle by rotating the steering device and wherein the steering device is configured to allow rotation of the wire guide through complete revolutions;

directing a balloon catheter out the distal end of the guide catheter and into a drainage pathway of the sinus cavity, wherein the balloon catheter includes an inflatable balloon; and

inflating the balloon to dilate tissue of the drainage pathway.

2. The method of claim 1, wherein a distal tip of the wire guide is directed into the sinus cavity while the distal end of the guide catheter is positioned at a location outside of the sinus cavity.

3. The method of claim 1, wherein a distal portion of the balloon catheter is directed over the wire guide and into the sinus cavity.

4. The method of claim 1, wherein the wire guide is disposed within the balloon catheter when the tissue of the drainage pathway is dilated.

5. The method of claim 1, wherein the proximal end of the guide catheter includes a hub.

6. The method of claim 1, wherein the sinus cavity is a maxillary sinus cavity.

7. The method of claim 1, wherein the sinus cavity is a frontal sinus cavity.

8. The method of claim 1, wherein the sinus cavity is a sphenoid sinus cavity.

9. The method of claim 1, further including assembling the wire guide to the steering device.

10. The method of claim 1, wherein sliding the steering device along the recess in a direction parallel to a major longitudinal axis of the handle and rotational movement of the steering device occur separately.

11. The method of claim 1, wherein the steering device is textured.

12. The method of claim 1, wherein a thumb is used to slide the steering device along the recess.

13. The method of claim 1, wherein the guide catheter is removably secured to the handle.

14. The method of claim 13, wherein the guide catheter is removably secured to the handle via a frictional fit.

15. The method of claim 1, wherein the guide catheter and the wire guide are positioned within the nasal passage using a single hand.

16. The method of claim 1, wherein the steering device advances with the wire guide in the direction parallel to the major longitudinal axis of the handle.
