Abstract
A cuff for use an as artificial sphincter includes an inflatable chamber and a backing. The inflatable chamber includes opposing inside and outside surfaces and inflated and deflated states. The backing is adjacent the outside surface of the chamber. The inside surface of the chamber includes two or more grooves that define the location of fold lines of the inflatable chamber when the inflatable chamber is in the inflated state. The inflatable chamber and backing are configured to surround a duct of a patient with the inside surface of the chamber facing the duct and the grooves extending substantially parallel to the duct.
