A method and apparatus is disclosed for providing therapy for acute or chronic wounds and other clinical conditions, and/or for altering flow of bodily fluids, that uses pressure and temperature to promote healing or comfort. The pressure can be negative, positive, or cyclic to promote bodily fluid flow, particularly in cases of venous insufficiency. The pressure is supplied by a chamber that encases the desired site and seals to the skin of the patient, and a pump that controls the pressure within the chamber. The temperature is supplied by a heat exchange surface in proximity to the skin within the area surrounded by the pressure chamber, and can be any temperature within the range of physiological tolerance; including temperatures both above and below normal physiological temperatures. The temperature of the heat exchange surface is controlled by an apparatus outside the chamber, and may be continuous or cyclic. The heat exchange surface may have a disposable covering that serves as a wound dressing. Generally, the heat exchange surface is applied to the skin surface at a desired temperature, the chamber is sealed over the area, and pressure is drawn. The patient may be treated over a period of time ranging from minutes to weeks or months.
