Prostheses, Anal Sphincter
Definition : Implantable prostheses designed to functionally replace the anal sphincter. These prostheses are typically surgically implantable hydraulic devices with a fluid reservoir (e.g., balloon), a mechanism with a small pump that is appropriately situated under the skin, and an inflatable and deflatable cuff that surrounds the anal canal; the components are usually connected to each other using silastic tubes. Other devices intended to occlude the bowel by reproducing the action of the puborectal muscle are also available. Anal sphincter prostheses are used to help the patient control moderate to severe continence; the cuff remains inflated to maintain continence and is deflated by the user to produce a bowel movement.
