Abstract
An embodiment of a cuff for use an as artificial sphincter comprises 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 and/or the backing include two or more grooves that define the location of fold lines of the inflatable chamber when the inflatable chamber is in the inflated state.
Claims19
A cuff for use as an artificial sphincter around a duct of a patient, the cuff comprising:
- an inflatable chamber having an inside surface and an outside surface opposite the inside surface, the chamber having an inflated state and a deflated state;
- and
- a backing adjacent the outside surface of the chamber;
- wherein:
- at least one of the inside surface and the backing include two or more grooves that define the location of fold lines of the inflatable chamber when the inflatable chamber is in the inflated state;
- and
- the inflatable chamber and backing layer 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.
