1. A method of measuring the size of a body lumen comprising:

  • expanding a size of an operative element within the lumen, the operative element having sensing circuitry with a resistivity that varies according to the size of the operative element;

    varying the sensing circuitry in accordance with the size of the operative element;

    measuring the resistivity of the sensing circuitry; and

    determining the size of the lumen based on the measuring step.
