Abstract
A method for evaluating flow characteristics in a vessel of a patient includes the steps of 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. In some embodiments, the method may further comprise the step of detecting an endovascular electrogram signal. The method may be designed for evaluating flow characteristics in a vessel of a patient while enabling the prevention of a balloon from over-expanding and/or over-distending a vessel of a patient.
