Patent ID: 8905922

Claim:
A system comprising: (a) a light emitting wire having a proximal end, a distal end, and a light emitting portion at or near the distal end, wherein the light emitting portion is configured to pass into a paranasal sinus; (b) a guide catheter configured to facilitate advancement of the light emitting portion of the light emitting wire into the paranasal sinus, wherein the light emitting wire is passable through the guide catheter; and (c) a flexible catheter passable over the light emitting wire; wherein the light emitting wire and the flexible catheter are configured and operable such that a distal end of the flexible catheter is positionable proximal to a distal end of the light emitting wire while the light emitting wire is disposed in the flexible catheter, such that the distal end of the light emitting wire is distal to the distal end of the flexible catheter; wherein the light emitting wire is operable to emit light of a character such that emitted light is directly observable exterior of a patient's anatomy through tissue overlaying the paranasal sinus.
