1. A computational catheter device, useful in association with a dynamic body system, the computational catheter device comprising:

  • at least one fluid pathway;

    at least one pressure sensor configured to generate a pressure signal within an anatomical vessel for a dynamic body system;

    at least one external sensor configured to collect a fundamental frequency generated by at least one of a cardiovascular pulsation and external oscillator;

    a modeler configured to generate a predicted signal through the anatomical vessel using the collected fundamental frequency; and

    a spectral analyzer configured to generate a calibration by comparing the predicted signal to the pressure signal to identify obstructions within the anatomical vessel.
