Part of the closing mechanism is a moving part (11 21, 22 31, 32, 33 51) adapted to make movements to assume an open and a closed position for opening and closing of the blood vessel and positions between said open and closed positions. the closing mechanism (11 21, 22 31, 32, 33 51) is adapted to let the moving part initiate and carry out its movements when a predefined threshold value is reached by a physical parameter of the mammal or a functional parameter of a device (8) used by the mammal. The closing mechanism is arranged to power at least one of said movements of the moving part (51) and to let a movement of the moving part take place passively.
