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 treating a natural ostium of the maxillary sinus of a patient comprising:

traversing the canine fossa region of the patient by piercing the canine fossa region with a sharpened tool so as to form a passageway to a the maxillary sinus cavity;

cannulating the passageway with a cannula;

inserting an elongate member through the cannula disposed in the passageway, the elongate member having an inflation member disposed thereon;

positioning the inflation member within the natural ostium of the maxillary sinus; and

expanding the inflation member so as to expand at least a portion of the natural ostium of the maxillary sinus.

2. The method of claim 1, further comprising a stop disposed on the sharpened tool configured to limit distal advancement of the tool within the maxillary sinus cavity.

3. The method of claim 1, wherein the inflation member is positioned within the natural ostium of the maxillary sinus by advancing the elongate member over a wire guide passing through the passageway.

4. The method of claim 1, wherein the inflation member is positioned using one or more markers contained thereon.

5. The method of claim 1, wherein the elongate member comprises a balloon catheter.

6. The method of claim 1, further comprising advancing a visualization tool through the cannula and imaging the natural ostium of the maxillary sinus.

7. The method of claim 6, wherein the visualization tool comprises an endoscope.

8. The method of claim 6, wherein the inflation member is expanded while being visualized with the visualization tool.

9. The method of claim 1, wherein the canine fossa region is traversed with the cannula disposed on sharpened tool.

10. The method of claim 9, wherein the sharpened tool is withdrawn prior to inserting an elongate member through the cannula.
