1. A method of evaluating flow characteristics in a vessel of a patient, comprising:

  • positioning a catheter having a balloon at a measuring location within the vessel;

    transmitting an ultrasound signal into the vessel while the balloon catheter is within the measuring location;

    evaluating a reflection of the ultrasound signal to determine a flow parameter within the vessel while the catheter is in the measuring position;

    expanding the balloon within the vessel at the measuring location; and

    stopping the expanding step when the result of the evaluating step is that the flow through the vessel is substantially stopped.
