Abstract
An improved artificial sphincter for occluding a duct. The basic sphincter includes means to increase the occlusive force about the duct and means to control the increase of such occlusive force. To protect the duct from excessive or damaging occlusion the basic sphincter is improved by including means for preventing increase of the occlusive force about the duct beyond a predetermined position. An additional improvement includes means for adjusting the occlusive means after the sphincter has been implanted in a human or animal body to account for variations in fit about different ducts.
