摘要：
An apparatus comprises a guidewire body and a light source. The guidewire body includes an optically transmissive element. The guidewire body is sized for insertion in a sinus ostium of a patient. The light source is in optical communication with the optically transmissive element of the guidewire body. The light source is operable to transmit infrared light or narrowband visible light through the optically transmissive element. A detector may be used to detect light transmitted by the optically transmissive element through the patient. The detector may include a camera or a photodetector. Glasses may be used to provide an overlay of a camera image or to filter out light to enable focusing on light of a specific wavelength. A beam processing element may be used to provide a beam waist with an average irradiance of more than 10 W/cm2 within the acceptance angle of the optically transmissive element.
