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.

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.

Abstract: A method of treating diseased ethmoid sinuses in a patient with a therapeutic agent includes providing an injection device comprising an elongate member having a proximal end, a distal tip or end, and a lumen extending between the distal tip or end and the proximal end, the proximal end being operatively coupled to a source of the therapeutic agent. The distal tip or end of the injection device is inserted at least partially within an interior portion of an ethmoid air cell. The therapeutic agent is then injected into the interior portion of the ethmoid air cell using the injection device, the therapeutic agent being delivered via the lumen in the elongate member.

Abstract: A method of confirming the location of an elongate member configured for placement within a patient's sinus cavity comprises introducing the elongate member through a nasal passageway to place a distal tip of the elongate member in a test position, the elongate member configured to emit illuminating light via the distal end of the elongate member. The location of the light is then viewed through the patient's skin to confirm the positioning of the elongate member.

Abstract: A method of remodeling the uncinate process associated with a paranasal sinus includes positioning at least one shim member in the infundibulum, the shim member deforming the uncinate process and widening at least a portion of the infundibulum. The infundibulum space may be dilated with a dilating member. Dilation may occur prior to delivery of the at least one shim. The dilation member may be delivered into the sinus cavity via an access passageway formed in the canine fossa.
