摘要

Controllable stomach band comprises a rigid back (4), a first chamber (2) arranged on the stoma side of the back to control stoma constriction by introduction and removal of fluid from the chamber, and a second chamber (1) arranged on the stoma side of the back and connected to the first chamber so that the stoma inlet can be controlled by displacing liquid between one chamber and the other. Preferred Features: The second chamber is divided into two communicating chambers which delimit the stoma-narrowing chamber on both sides.
