"The Arctic Sun Temperature Management System is a non-invasive targeted temperature management system, a medical device used to modulate patient temperature with precision by circulating chilled water in pads directly adhered to the patient's skin. Using varying water temperatures and a sophisticated computer algorithm, a patient's body temperature can be controlled to the nearest 0.2 °C. It is produced by Medivance, Inc. of Louisville, Colorado." [1]

For those who don't know what Arctic Sun is, like me.
