1. A method of confirming a location of a distal tip of a device placed within a sinus cavity of a patient comprising:
- introducing a directable endoscope into a nasal passageway of the patient and placing a distal end of the endoscope superior to a uncinate process;
directing a viewing field of the endoscope in a retrograde direction and towards a sinus ostium;
advancing a guide catheter into the nasal passageway, wherein a proximal end of the guide catheter is removably secured to a distal end of a handle, and wherein the handle defines a steering device recess that opens along an axial length of a side surface of the handle, and wherein a steering device is positioned within the steering device recess and disposed on a wire guide, and wherein the steering device is configured to advance with the wire guide by sliding within the steering device recess and along the axial length of the handle, and wherein the steering device is configured to provide rotation of the wire guide through complete revolutions while the steering device is positioned within the steering device recess;
advancing the wire guide into the sinus cavity, wherein advancing the wire guide comprises sliding the wire guide within the steering device recess and rotating the steering device relative to the handle;
inputting light to the sinus cavity via a proximal light port disposed external to the patient; and
viewing the location of the emitted light to confirm the location of the wire guide.

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.

18. A method of confirming the location of a distal tip of a device placed within a sinus cavity of a patient, the method comprising:
-
releasably securing a distal end of a handle to a proximal end of a guide catheter, wherein the handle defines a steering device recess that opens along an axial length of a side surface of the handle, and wherein a steering device is positioned within the steering device recess and disposed on a wire guide, wherein the steering device is configured to allow rotation of the wire guide through complete revolutions; gripping the handle with a first hand of an operator and directing the guide catheter into a nasal passageway of the patient; advancing a distal portion of the wire guide out of a distal end of the guide catheter and into a desired sinus cavity of the patient, wherein the advancing comprises sliding the steering device axially within the steering device recess and rotation of the steering device relative to the handle; emitting light into the sinus cavity; viewing a location of the emitted light; advancing a balloon catheter out of the distal end of the guide catheter and across an ostium of the desired sinus cavity if the location of the emitted light is confirmed to be in a desired location; and dilating the ostium of the desired sinus cavity with the balloon catheter. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
