<p>A flexible catheter having an inflatable member at one end for insertion into a body cavity to seal same against fluid loss. 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. The disc prevents accidental perforation of the uterus and, with the inflated member affords stability to facilitate uterus manipulation. 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.</p> |
