The deflectable section comprises rigid rings and flexible connection members connecting the rings to each other. The connection members are comprised of a superelastic shape memory alloy. The connection members retain the deflectable section in a predetermined shape. The connection members can be resiliently bent to bend the deflectable section without permanent deformation of the connection member over a working life of the endoscope.
