Abstract
An endoscope comprising a control section and a shaft extending from the control section. The shaft has a frame with a one-piece tube along a majority of a length of the shaft. The tube comprises a superelastic alloy and slots into the tube along at least one-section of the tube. Superelastic properties of the superelastic alloy allow the tube to bend proximate the slots without substantial permanent deformation of the tube. The superelastic alloy provides the shaft with adequate stiffness and torque resistance to be inserted into a patient's body.
