Prosthetic Sphincter Controls Urination
Abstract
People who lost muscular control of urinary canal through disease or injury aided by prosthetic sphincter. Implanted so it surrounds uretha, sphincter deflated and inflated at will by wearer to start and stop urina tion. Operating pressure adjusted after implantation to accommodate growth or atrophy of urinary canal and prevent tissue damage from excess pressure. Principle adapted to other organs, such as colon, ureter, or ileum.
