A method and apparatus for the prevention of deep vein thrombosis (DVT), pulmonary embolism (PE), lower extremity edema, and other associated medical conditions by adjusting the temperature of the muscles of a foot or a leg, and/or applying vacuum or negative pressure to increase blood flow. A human extremity such as a leg is exposed to a negative pressure environment and/or a thermally controlled environment within a medical device. In one aspect, the device is portable. A thermal exchange unit and, optionally, a vacuum or negative pressure unit, are provided to increase blood flow and vasodilation. The device can be programmed by a controller in a manner to stimulate the muscles of the extremity to reduce pooling of blood therein.

1. An apparatus for providing a therapy useful to prevent deep vein thrombosis (DVT), comprising: a chamber body at least partially defining an enclosed region, wherein the chamber body is adapted to flex;a vacu-seal comprising: a vacu-sealing portion disposed over an opening formed in the chamber body, wherein a surface of the vacu-sealing portion is adapted to form a seal with at least a portion of the chamber body; anda vacu-seal body portion coupled to the vacu-sealing portion and adapted to enclose one or more portions of a human extremity therein, wherein the vacu-seal body portion is disposed within the enclosed region and at least partially defines a space formed between a surface of the vacu-seal body portion and a surface of the chamber body;one or more thermal exchange units disposed within the enclosed region;one or more thermal exchange supply lines and one or more thermal exchange return lines attached to the one or more thermal exchange units;one or more apertures formed in the chamber body, wherein the one or more thermal exchange units are connected to one or more thermal sources via the one or more thermal exchange supply lines and the one or more thermal exchange return lines through at least one of the one or more apertures in the chamber body; andone or more compression pads for applying an intermittent compression pressure to one or more portions of the human extremity. 2. The apparatus of claim 1, wherein the chamber body comprises one or more materials selected from the group consisting of polystyrenes, high density polyethylenes (HDPE), low density polyethylenes (LDPE), poly(vinyl chloride), urethanes and polyurethanes. 3. The apparatus of claim 2, wherein the chamber body comprises a soft chamber body. 4. The apparatus of claim 1, further comprising one or more additional apertures formed in a wall of the chamber body, wherein the one or more additional apertures are adapted to connect at least one vacuum pump to the space formed between the surface of the vacu-seal body portion and the surface of the chamber body. 5. The apparatus of claim 4, wherein the at least one vacuum pump is configured to form a pressure within the space of between about zero and about −120 mm-Hg. 6. The apparatus of claim 5, further comprising a vacuum sensor port formed in a wall of the chamber body. 7. The apparatus of claim 1, wherein the chamber body and the vacu-seal are disposable. 8. The apparatus of claim 1, wherein the vacu-seal is detachably attached to the chamber body. 9. The apparatus of claim 1, wherein the one or more thermal exchange units are adapted to receive a fluid medium selected from the group consisting of heated fluids, heated air, cooled fluids, cooled air, and combinations thereof. 10. The apparatus of claim 1, wherein the one or more thermal exchange units are electric pads. 11. The apparatus of claim 1, wherein the one or more thermal exchange units are detachably placed inside the enclosed region. 12. The apparatus of claim 1, further comprising one or more flexible membranes positioned between the one or more thermal exchange units and the chamber body. 13. The apparatus of claim 1, further comprising a temperature sensor adapted to monitor the temperature of the portion of the human extremity. 14. The apparatus of claim 1, wherein the one or more portions of the human extremity is selected from the group consisting of a foot, a leg, a calf, an ankle, and any combinations thereof. 15. The apparatus of claim 1, wherein the one or more apertures are further configured to receive a vacuum port that is connected to at least one vacuum pump and to the space formed between the surface of the vacu-seal body portion and the surface of the chamber body. 16. A method of preventing deep vein thrombosis (DVT), comprising: disposing one or more extremities of a mammal in one or more devices, each device comprising: a chamber body at least partially defining an enclosed region;a vacu-seal comprising: a vacu-sealing portion disposed over an opening formed in the chamber body, wherein a surface of the vacu-sealing portion is detachably disposed over at least a portion of the chamber body; anda vacu-seal body conjoined with the vacu-sealing portion and configured to receive a portion of the one or more extremities, wherein a space is formed between the chamber body and both the vacu-seal body and at least a portion of the vacu-sealing portion when the one or more extremities are enclosed within the vacu-seal body and the vacu-seal body and the one or more extremities are disposed in the enclosed region defined by the chamber body; andone or more thermal exchange units;regulating the temperature of the one or more extremities of the mammal using the one or more devices, therebyvasodilating an arteriovenous anastomoses (AVAs) blood vessel in the one or more extremities of the mammal,increasing blood flow in the one or more extremities and decreasing the chance of clotting in the veins in the one or more extremities. 17. The method of claim 16, further comprising applying compression forces to a portion of the one or more extremities of the mammal. 18. The method of claim 17, wherein the compression forces are applied by one or more pressurized compression pads within the one or more devices. 19. The method of claim 17, wherein the compression forces are applied by a pressurized compression device separate from the one or more devices. 20. The method of claim 16, further comprising reducing the pressure within the enclosed region of the one or more devices. 21. The method of claim 20, wherein the pressure is reduced to a pressure between about zero and about −120 mm-Hg. 22. The method of claim 20, wherein the one or more extremities are one or more legs. 23. The method of claim 16, wherein the temperature of the one or more extremities are maintained by the one or more devices to between about 10° C. and about 42° C.
