ABSTRACT:
Microfluidic shunt valves are disclosed having a deflectable element capable of being held in a closed position to occlude the passage of fluid between an inlet and outlet and, when not held in the closed position, the deflectable element is adapted to oscillate in response to fluid pressure pulses and thereby facilitate fluid passage through the valve. Controls for activating the deflectable element to permit fluid passage are also included.
