1. Apparatus for mapping an interior surface of a lumen of a patient'"'"'s vasculature, the apparatus adapted for connection to a display device, the apparatus comprising:

  • a catheter having a proximal end, a distal end, and a portion defining a guide wire lumen, the catheter configured for percutaneous, transluminal insertion in the patient'"'"'s vasculature along a guide wire;

    a first contact disposed on the distal end, the first contact having a feature that varies as a function of a deflection imposed on the first contact by the interior surface of the lumen;

    circuitry for measuring the feature;

    circuitry for correlating the measured feature to the deflection and for providing an output to the display device corresponding to the deflection.
