Abstract
A drainage tube for controlling a patient's temperature and draining fluids from a patient's chest or other body cavity includes a generally tubular elongate body having one or more drainage lumens with one or more drainage ports disposed along the distal portion of the drainage tube. The drainage tube also comprises one or more flow lumens for transporting a heat exchange fluid to one or more heat exchange elements that exchange heat with tissue in the patient's chest or other body cavity. The drainage tube may have an internal heating element that heats or cools the heat exchange fluid. A heat exchange element may include an everting balloon that expands out of a cavity in the elongate body after intubation of the drainage tube. The expansion of the everting balloon may be assisted with a moveable inner shaft disposed in the elongate body.
