Systems, devices and garments for surface temperature therapy of a patient
A conformable garment or device, for example, for performing heat exchange with a patient, includes one or more tubes. At least one of the one or more tubes has a lumen configured to receive fluid for flowing through the lumen of that tube to heat or cool the tube. The one or more tubes may be coupled to form a conformable fabric or material, such that the conformable fabric or material conforms to a non-planar shape. The conformable garment or device may conform to cover a particular portion of the patient's body to heat or cool the patient's body.
