ABSTRACT:
A method of constructing an articulation joint includes forming a metallic tube with a number of rings formed therein. Springs may be secured to the inside surface or outside surface of the rings to allow the joint to bend in directions transverse to the axis of the springs. A fixture may be used to hold the springs at the correct position within the tube and the springs may be urged toward the rings or vice versa to obtain a good bond between the springs and the rings.
