1. An implantable wireless sensor for determining a pressure of a lumen in a body, comprising:
a sensor body comprising a plurality of substrates, at least a portion of the substrates comprising a first dielectric material;
an LC resonant circuit contained with the sensor body, a capacitance of the LC resonant circuit configured to vary in response to changes in pressure in the lumen;
a first anchoring element coupled to a proximal end of the sensor body and a second anchoring element coupled to a distal end of the sensor body, the first and second anchoring elements configured to lodge the sensor body within the lumen; and
a second dielectric material, different than the first dielectric material, provided over at least a portion of at least one of the plurality of substrates.
