Abstract
A deflection cover for a medical endoscope comprises a tubular covering that protects the articulation system of an endoscope during sterilization procedures where pressure differentials are generated. The deflection cover is of a single layer of a selected material whose properties provide the deflection cover with adequate flexibility, thinness, and strength for use on a medical endoscope. The deflection cover may include a reinforcement structure, such as a helically oriented thread, to increase the tube's pressure resistance without impeding the tube's longitudinal flexibility, which is needed to allow the articulation system in the endoscope to deflect through its intended range of motion.
