Patent ID: 7334594

Claim:
A shunt valve assembly comprising: a housing having an inlet port and an outlet port, the housing configured to carry a fluid between the inlet port and the outlet port; a valve coupled to the housing and in fluid communication with the inlet port and the outlet port, the valve having a pressure setting mechanism configured to adjust a pressure at which the valve will release fluid from the inlet port to the outlet port; an electromechanical brake assembly having a brake member disposed in proximity to the pressure setting mechanism; and a signal receiver in electrical communication with the electromechanical brake assembly, the signal receiver configured to receive an activation signal and transmit a positioning signal to the electromechanical brake assembly, in response to receiving the activation signal, to: (i) position the brake member in a first position relative to the pressure setting mechanism when the activation signal has a first value, and (ii) position the brake member in a second position relative to the pressure setting mechanism when the activation signal has a second value.
