Torque transmission test fixture setup and test result. (a) The distal shaft is fixed to a freely-rotating collet (arrow) that indicates the angular response to torque. (b) A meter on the proximal shaft recorded transmitted torque after 90–270° tip rotation. (c) Comparative torquability values for different braiding layer configurations. Higher torque response values indicate greater torquability.
