A therapeutic device for a body portion utilizing a thermal responsive medium includes a first flexible layer having a plurality of interconnected raised chambers and passageways. The upper surface of a second flexible layer is sealingly engaged to the lower surface of the first flexible layer to form a plurality of chambers spaced from each other and connected by the passageways. The chambers and the passageways are filled with a thermal responsive medium which is heated, cooled or frozen, depending on the use. For applying heat treatment a third flexible layer is sealingly engaged to the lower surface of the second flexible layer, and a flexible insulating member is removably connected to the lower surface of the third flexible layer. The flexible insulating member has a plurality of raised cells containing an insulating medium. The therapeutic device is heated to a desired elevated temperature, and a flexible insulating member is wetted with an aqueous solution and connected to the heated flexible therapeutic device for moist heat application. The heated therapeutic device is then applied to the body portion with the cells of the flexible insulating member positioned against the body portion to be treated. Similarly in cold treatment, the flexible insulating member may or may not be used. In both hot and cold treatment applications, the therapeutic device is compressively held in close conformity to the body portion to be treated to enhance the rate of transfer of hot or cold temperature to the affected body portion.
