Abstract:
1. An implantable apparatus for controlling fluid flow within a host body comprising: a constricting member for allowing fluid flow within a body canal when in an open position and for reducing fluid flow within a body canal when in a closed position, said constricting member comprising an engaging element for substantially encircling a portion of said canal, said constricting member further comprising a fluid-operated structure which receives fluid to reduce fluid flow within said body canal and expels fluid to allow fluid flow within said body canal, wherein said fluid-operated structure comprises a bladder, said bladder being positioned in said constricting member such that expansion of said bladder upon receiving said fluid will cause said bladder to compress said canal against said engaging element and reduce fluid flow within said body canal; an actuating member for operating the constricting member between said open position and said closed position, said actuating member comprising a means for flowing fluid into and out of said fluid-operated structure; and control means for operating said actuating member.
