Abstract: To offload forces from a tissue site being treated with reduced pressure, an offloading pressure component may be used as part of a reduced-pressure treatment system. A reduced-pressure source of the reduced-pressure treatment system vents positive pressure exhaust into the offloading pressure component to inflate the offloading pressure component. The offloading pressure component disperses forces away from the tissue site. Other devices, methods, and systems are presented.

Abstract: Wounds dressings, systems, and methods are presented that involve using a patient's body heat to enhance liquid removal from the wound dressing through a high-moisture-vapor-transmission-rate drape. Additional heat sources or devices, such as nano-antennas or electrical heating elements, may be added or used separately to enhance the removal liquid from the wound dressing. Other dressings, systems, and methods are presented herein.
