ABSTRACT:
A nasal sinus endoscope system and method. The system comprises a nasal sinus endoscope having a distal viewing window. A resilient tube is attached to the endoscope such that the distal end of the tube is in proximity to the distal viewing window of the endoscope, and a syringe is connected to the proximal end of the resilient tube for selectively forcing fluid through the tube and out of the distal end thereof. The distal end of the resilient tube preferably forms an oblique angle with respect to a longitudinal axis of the tube, and the resilient tube is attached to the endoscope such that the oblique opening formed by the distal end of the tube substantially faces the endoscope. The resilient tube is attached to the endoscope by means of suitable fasteners, such as, for example, elastic bands which encircle both the tube and the endoscope.
