The devices and methods are 4 particularly well-suited to implantation within the body of a living animal or human to 5 monitor physiological conditions, such as portal and/or hepatic venous blood pressure, 6 and allow frequent, remote interrogation of venous pressure using the resonance 7 frequency of an implanted sensor. The sensor devices are relatively small compared to 8 conventional devices for measuring fluid pressure and can be implanted in the porto9 hepatic venous system, whereas conventional devices are too large. The small size of the 0 device is accomplished by using a thick sensor membrane, compared to conventional 1 devices, and by limiting the size of additional elements of the device relative to the size 2 of the sensor membrane. The thicker sensor member also obviates the need for multiple 3 sensor arrays and maintains the accuracy and robustness of the sensor device. A data 4 capture, processing, and display system provides a pressure measurement reading, and is 5 particularly well-suited for detecting portal hypertension in patients with liver disorders.
