Abstract:
1. A system 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 the body canal when in a closed position, wherein the constricting member comprises a plunging member having at least two protrusions adapted to contact the body canal such that only one or more outer edges of the at least two protrusions of the plunging member contacts the body canal, thereby allowing pressure to be placed on the body canal over a smaller area and substantially reducing the likelihood of necrosis of the tissue of the body canal; an actuator for operating the constricting member between the open position and the closed position; and a control structure for operating said actuator, said control structure being operated by a telemetry device from a position outside the host body.
