| Summary: | This invention relates to methods and apparatus for selectively controlling the temperature of a surface, and more particularly to a roller adapted to cool or heat a surface as it is rolled thereover and to methods for the utilization of such roller.
A method and apparatus are provided for controlling the temperature of a surface to preheat or precool the surface, to heat or cool the surface to effect a therapeutic treatment or to post-heat or post-cool the surface. A roller, preferably mounted to a handle, is provided which contains a material which is heated or cooled prior to treatment as appropriate so as to undergo a phase change and is then rolled over the surface the temperature of which is to be controlled, gradually undergoing a phase change to return to its initial state as it is rolled over the surface to effect the desired heating or cooling of the surface. The roller preferably has a large internal surface area in contact with the material undergoing the phase change. |
