摘要： A shunt valve assembly includes an electromechanical brake mechanism that locks a position of a pressure setting mechanism within a shunt valve assembly. The electromechanical brake can maintain the position of the pressure setting mechanism in the presence of a relatively strong magnetic field to maintain a set pressure differential within the shunt valve assembly. In certain cases, the shunt valve requires repositioning of the pressure setting mechanism within the shunt valve assembly to adjust a fluid flow rate through the shunt valve assembly. A clinician can activate an external controller to transmit a signal to the shunt valve assembly through magnetically coupled antennas between the controller and the shunt valve. The shunt valve assembly utilizes the signal to activate the braking mechanism and unlock the pressure setting mechanism. The clinician then operates the controller to non-invasively reposition the pressure setting mechanism and adjust the pressure at which the shunt valve opens.

摘要： A miniature implantable magnetically actuated valve relatively insensitive to normally-encountered shock loads includes a housing for containing a movable ferromagnetic valve member. Inlet and outlet passages are provided in the housing at least one of which has an internal valve seat which is engageable by the valve member to close that passage. The valve member is resiliently suspended within the housing by special flat multiply-started spiral springs which permit the valve member only a single degree of freedom toward and away from the valve seat. The valve member is biased in one direction or the other and the valve is actuated transcutaneously by a magnet juxtaposed to the valve outside the body which produces a magnetic force on the valve member which exceeds and opposes the biasing force.
