APPARATUS AND METHOD FOR TREATMENT OF SINUSITIS
First Claim
1. A method of treating sinusitis in a patient comprising:
- forming an artificial access passageway into a sinus cavity of the patient;
positioning a cannula within the access passageway, the cannula having a first lumen adapted for passage of a balloon dilation catheter, and a secondary lumen adapted for passage of a visualization tool;
inserting the visualization tool into the secondary lumen and visualizing an anatomical region of interest;
inserting the balloon dilation catheter into the first lumen and advancing the same so as to place the dilation balloon in or across the anatomical region of interest; and
dilating the dilation balloon.

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. A cannula is positioned in the passageway. A visualization tool such as an endoscope is passed through a lumen or channel in the cannula to aid in visualization of the anatomical site of interest. A balloon dilation catheter is then deployed through or along the cannula so as to place the balloon within or across the constricted anatomical space (e.g., ostium). The balloon is then expanded so as to expand at least a portion of the constricted anatomical space. Alternative embodiments include the use of an optional guide wire and incorporating a endoscope lumen through the balloon dilation catheter.
