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