1. A method for determining a pressure associated with a lumen of a body, comprising:
positioning a wireless sensor in the lumen of the body, the sensor comprising an inductive-capacitive (LC) resonant circuit having a resonant frequency configured to vary in response to changes in pressure in the lumen;
storing one or more sensor calibration parameters at an external base unit;
generating an energizing signal from the external base unit;
transmitting the energizing signal;
receiving a ring down response from the wireless sensor;
determining the resonant frequency of the LC resonant circuit from the ring down response; and
calculating 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.
