Abstract
An endoscope comprising a handle and a flexible shaft connected to the handle. The flexible shaft has an active deflection section and a passive deflection section with a control wire support member therein. The endoscope also has a control wire connected to the active deflection section. A portion of the control wire is housed in the control wire support member. The control wire support member is made from a superelastic alloy material and is resiliently deflectable bending with the passive deflection section without permanent deformation or substantial fatigue over a working life of the endoscope.
