Abstract
An inflatable, adjustable implantable band for encircling an anatomical passageway to create an artificial stoma. The band is made of a flexible silicone tube having a first lumen enclosing at least one band or wire of a material such as nitinol having a thermal shape memory. The flexible tube is a double lumen tube in which the nitinol band or wire is enclosed in the first lumen and the second lumen is fluid inflatable from outside the patient to final adjustment of the internal diameter of the ring. The implantable band is easier to implant and more comfortable to the patient than known devices. Controlling and adjusting the internal diameter is very easy to perform by adding cold saline or water to the lumens to straighten out the ring so that it can be removed or by adding a warm or hot fluid to adapt it to a ring-shape.
