| 1. In a system in which a working fluid is circulated through a catheter and a heal transfer element, the working fluid having
a temperature different from a patient temperature, a method of controlling the administration of a thermal therapy, comprising:
entering a target patient temperature into the system;
inserting a catheter having a heat transfer element positioned at a distal tip of the catheter into a blood vessel of a patient,
the catheter having a supply lumen fin supplying a working fluid to the heat transfer element and a return lumen for returning
a working fluid from the heat transfer element;
circulating a working fluid through the catheter and the heat transfer element, the working fluid having a temperature different
from the patient temperature;
circulating a working fluid and not determining a control temperature, for a predetermined period of time based on the difference
between a temperature determined from a signal from a temperature sensor mounted at or adjacent the distal tip of the heat
transfer element and the target patient temperature;
after the predetermined period of time, receiving a signal from the temperature sensor and determining a control temperature
based on the signal;
using the control temperature to control the temperature of the working fluid.
