Abstract
The inflatable cuff of an artificial sphincter is secured in place about a natural body passage by fastening means which consist of a reinforcing belt for encircling the cuff and a clip to hold the belt in place. The belt has a reinforcing intermediate section of substantially uniform thickness throughout and a pair of ends, each of which have enlarged beads at their tips. At least one of the ends of the belt has a pair of spaced apart fingers which are especially useful for extending through the mesentery without interfering with the blood supply of said passage and the clip has bead receiving and retaining cavities for securing the belt in place.
