Abstract
A prosthetic anal sphincter is described which is implantable around the upper anal canal to reproduce the action of the sphincter muscles which maintain continence. This is achieved by inflating a tube with liquid from a reservoir and creating an angle of about 90.degree. between the rectum and the anal canal and by flattening the upper anal canal by squeezing the posterior wall of anal canal against the anterior wall.
