An apparatus for managing urinary flow in a host and having normally closed and actuated open states; operating similar to properly functioning sphincter. The apparatus consists of a funnel, at least one fixing arrangement, a closure member, a motive member, and an external control member. In one embodiment, the funnel is adapted to be located inside a host's bladder and urethra and is adapted to be removably fixed in place by the fixing arrangements. A housing separates the motive member components from the external environment such as urinary tract tissue and fluids. In an alternate embodiment, the housing also separates the closure member from the external environment. The motive member is in communication with the closure member and both are positioned with respect to the funnel for changing the state of the apparatus from normally closed to actuated open and vice versa. The motive member is in communication with and responsive to an external control member to place the closure member in a position corresponding to the apparatus state input to the external control member by an operator. In another embodiment, the funnel is constructed of material such that it may be rolled with the motive member and closure member for implanting in the host.
