Abstract
A device is provided for therapeutically treating a desired region of a patient's body with a nonambient temperature fluid which is circulated through a pad having a tortuous fluid pathway which is positioned on the treatment region. The device has fluid inlet and outlet lines, each having an end connected to the pad and an opposite end positioned in a reservoir containing the nonambient temperature fluid, thereby providing fluid communication between the pad and the reservoir, and enabling continuous circulation of the fluid therebetween. Fluid drive is provided by a submersible pump at the end of the fluid inlet line in the reservoir. Temperature control of the pad is enabled by an in-line valve and temperature monitor positioned in the outlet line.
