  • Device for preventing fecal incontinence
    Patent number: 6491623
    Abstract: An implantable device for controlling a body conduit including a cuff portion adapted to substantially encircle a body conduit. An inlet tube is operatively connected for delivering fluid to the cuff portion. The inlet tube has a one-way valve. An outlet tube is operatively connected to the cuff portion for releasing fluid therefrom and includes a normally closed valve. A pumping reservoir is in communication with the inlet tube and the outlet tube, wherein manipulation of the pumping reservoir inflates the cuff portion and manipulation of the normally closed valve deflates the cuff portion. An inflatable lumen surrounds the pumping reservoir and the cuff portion to provide rigidity and balance pressure between the cuff portion and the pumping reservoir.
