Claims20
A method for controlling core body temperature in a patient comprising:
- positioning a heat transfer device within the patient's esophagus, wherein the heat transfer device includes one or more lumens providing a fluid path for flow of a heat transfer medium;
- initiating flow of a heat transfer medium along the fluid path;
- and
- circulating the heat transfer medium along the fluid path for a time sufficient to control core body temperature without provoking a shivering response in the patient.
A method for treating or preventing ischemia-reperfusion injury in a patient comprising:
- positioning a heat transfer device within the patient's esophagus, wherein the heat transfer device includes one or more lumens providing a fluid path for flow of a heat transfer medium;
- initiating flow of a heat transfer medium along the fluid path;
- and
- circulating the heat transfer medium along the fluid path for a time sufficient to induce hypothermia or maintain normothermia;
- wherein the method does not include concomitant administration of anti-shivering interventions.
An esophageal heat transfer device comprising:
- a distal end configured for insertion into a nostril or mouth of a patient;
- a heat transfer region configured to directly contact esophageal epithelium of the patient, wherein the heat transfer region does not include a balloon or partially inflatable lumen;
- an input port for receiving a heat transfer medium from a source;
- and
- an output port that allows the heat transfer medium to return to the source.
An esophageal heat transfer device comprising:
- a distal end configured for insertion into a nostril or mouth of a patient;
- a heat transfer region having a diameter of about 1.0 to about 2.0 centimeters;
- an input port for receiving a heat transfer medium from a source;
- and
- an output port that allows the heat transfer medium to return to the source.
