Localized cooling catheter and localized cooling devices using the same

A catheter having no traffic hole with the outside by circulating hot cooling medium in the lumen of the catheter to cool the local, the epidural space of the spinal cord or brain, intrathecal or subarachnoid space indwelled inserted into or esophageal lumen within, by circulating a heat cooling medium into the lumen of the catheter, or the heat absorption part of a catheter, by means of a device composed of a heat insulating portion and the heat radiating portion, the the epidural space of the spinal cord or brain endothermic portion of the catheter was inserted into the intrathecal or subarachnoid space or the esophagus lumen indwelling, the heat insulating portion absorbs heat from the heat absorbing section by dissipating heat from the heat radiating portion through, it can be localized cooling spinal intrathecal pressure, spinal cord without varying the like intracranial pressure, cerebral and selectively and continuously and convenient managed in the esophagus , thoracic aorta Kobute Treatment of spinal cord diseases, including paraplegia prevention in, can contribute like for the treatment of brain injury and esophageal damage.
