Abstract:
1. A method for locating a sinus ostium, said method comprising the steps of: (a) inserting a sinus guide and an endoscope through a nostril of a patient; (b) advancing the sinus guide toward a location of the sinus ostium under the guidance of the endoscope; (c) inserting an illuminating guidewire through the sinus guide and into the nostril and advancing a distal end portion of the illuminating guidewire distally of a distal end of the endoscope and distally of a distal end of the sinus guide, wherein the distal end of the illuminating guidewire includes a light emitting feature; (d) viewing, through the endoscope, the advancement of the distal end portion of the illuminating guidewire to facilitate guidance of the advancement of the illuminating guidewire along a desired path; (e) identifying a location of the sinus ostium by observing a transillumination region, wherein the transillumination region is provided by illumination from the light emitting feature of the guidewire; (f) advancing a working device through the sinus guide to position the working device through a distal end of the sinus guide and into the sinus ostium after identifying the location of the sinus ostium by observing the transillumination region; and (h) actuating the working device to thereby perform a diagnostic or therapeutic function in one or both of the sinus ostium or an adjacent sinus cavity.
