Devices, systems and methods for diagnosing and treating sinusitis and other disorders of the ears, Nose and/or throat
First Claim
1. A method of confirming the location of the distal tip of a device placed within the sinus of a patient comprising:
- introducing an endoscope into a nasal passageway of the patient;
advancing a guide catheter into the nasal passageway under the endoscopic visualization;
advancing a distal tip of a light emitting elongate member through the guide catheter and into a desired sinus cavity;
inputting light to the light emitting elongate member via a proximal light port disposed external to the patient; and
viewing the location of the light through the patient'"'"'s skin and based on said viewing determining whether the distal tip of the light emitting elongate member is correctly located in the desired sinus cavity.

Abstract
Various diagnostic procedures and devices are used to perform imaging studies, mucus flow studies, air/gas flow studies, anatomic dimension studies, endoscopic studies and transillumination studies. Devices and methods for visually confirming the positioning of a distal end portion of an illuminating device placed within a patient include inserting a distal end portion of an illuminating device internally into a patient, emitting light from the distal end portion of the illuminating device, observing transillumination resulting from the light emitted from the distal end portion of the illuminating device that occurs on an external surface of the patient, and correlating the location of the observed transillumination on the external surface of the patient with an internal location of the patient that underlies the location of observed transillumination, to confirm positioning of the distal end portion of the illuminating device.
