Abstract: Embodiments of the invention include methods and devices for increasing blood flow and controlling the temperature of a mammal. The device generally includes collapsible and pliant body elements, capable of expanding from a first volume into an expanded second volume which can then be reduced from the expanded second volume into a pressurized third volume. One or more thermal exchange units can be positioned in the one or more collapsible and pliant body elements. Accordingly, the temperature of the extremity of a mammal can be regulated by providing heating or cooling to the one or more thermal exchange units.

Abstract: A method and device for increasing blood flow by applying positive pressure to extremities of a mammal and/or controlling the temperature of the mammal. The device includes one or more collapsible and pliant body elements capable of expanding and flexibly applying pressurized compression forces to the extremity of the mammal by attaching one or more pressure-applying gas plenums as close to the extremity as possibly. The flexible extremity device can be used independently or can be used in conjunction with thermal pads disposed to the one or more collapsible and pliant body elements. Alternatively, the one or more collapsible and pliant body elements can be manufactured into thermal pads.
