Abstract:
1. A locking assembly for preventing rotation of a rotor assembly of a shunt valve system, the locking assembly comprising: at least one protrusion configured to selectively frictionally engage the rotor assembly, the at least one protrusion having at least one rotor-contacting surface, the at least one protrusion being formed integrally with a wall of a housing of the shunt valve system; and an actuating mechanism mechanically linked to the protrusion wherein the actuating mechanism is effective to move the at least one protrusion between a locked position in which the at least one protrusion frictionally engages the rotor assembly and an unlocked position in which the at least one protrusion is disengaged from the rotor assembly.
