There is provided a method for controlling a flow of blood and/or other bodily matter in a blood vessel. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the wall of the blood vessel) at least one portion of the wall of the blood vessel to influence the flow in the blood vessel, and stimulating the constricted wall portion to cause contraction of the at least one portion of the wall to further influence the flow in the blood vessel. The method can be used for restricting or stopping the flow in the blood vessel, or for actively moving the blood in the blood vessel, with a low risk of injuring the blood vessel. |
