Bardex

Bardex is a brand of catheter, including enema catheters. A favourite in medical play, the bardex enema catheter has two bulbs that can be inflated - one inside, and the other outside of the anal sphincter. Once it is inflated, the catheter cannot easily be expelled from the anus and leakage from the intestines is prevented. This allows a top to force the bottom to retain an enema, even while cramping.
