A spring component biases the catheter outwardly of the cavity to assure seating of the inflated member against the cavity wall, A disc abuts a body part to load the spring component during catheter insertion.

An air line in the catheter wall admits air to the inflatable member. A stiffener enables the flexible catheter to be used for imparting movement to the body part.
