Claim 13:
14. A system, comprising:
an implantable wireless sensor for determining a pressure of a lumen of a body, the wireless sensor comprising an inductive-capacitive (LC) resonant circuit having a resonant frequency configured to vary in response to changes in pressure in the lumen; and
an external base unit connected to a coupling loop, the external base unit configured to:
store one or more sensor calibration parameters into the external base unit;
generate an energizing signal;
transmit the energizing signal;
receive a ring down response from the wireless sensor;
determine the resonant frequency of the LC resonant circuit from the ring down response; and
calculate the pressure in the lumen from the resonant frequency of the LC resonant circuit utilizing the one or more sensor calibration parameters associated with the LC resonant circuit.
