摘要：
An implantable medical device is disclosed that includes a valve seat and a valve member movable with respect to the valve seat. An adjustment circuit assembly includes a resistive element that is coupled to the valve member and operable to position the valve member relative to the valve seat so as to alter the pressure setting in response to a current applied to the resistive element. A reading circuit assembly includes an antenna coil, a sensing coil and a member moveable with respect to the sensing coil, the member configured to alter a resonant frequency of the reading circuit assembly as a function of a position of the member with respect to the sensing coil.
