1. A method comprising:
- positioning a catheter within a patient'"'"'s vasculature, wherein the catheter includes a thermal source and a thermal detector;
delivering thermal energy to the patient'"'"'s vasculature from the thermal source;
making a plurality of temperature measurements near or at the thermal source using the thermal detector as the catheter is advanced through the patient'"'"'s vasculature while delivering thermal energy; and
using the temperature measurements to determine the position of the catheter with respect to a blockage in the patient'"'"'s vasculature.
