There is provided a method for controlling a flow of eggs in a uterine tube formed by a uterine tube wall of a patient. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the uterine tube wall) at least one portion of the uterine tube wall to influence the flow of eggs in the uterine tube, and stimulating the constricted wall portion to cause contraction of the uterine tube wall portion to further influence the flow of eggs in the uterine tube. The method can be used for restricting or stopping the flow of eggs in the uterine tube, or for actively moving the fluid in the uterine tube, with a low risk of injuring the uterine tube.

An apparatus for controlling a flow of urine in a urethra of a patient is disclosed, comprising an implantable constriction device for constricting the urethra to influence the flow in the urinary tract. The constriction device comprises a plurality of constriction elements configured to be arranged at different locations along the flow direction of the urethra, wherein each constriction element is configured to at least partly encircle the urethra and to be operable so as to change a constriction of the urethra. The apparatus further comprises an operation device configured to operate the constriction elements.
