Device for producing concentric temperature waves on the skin of a patient has circular or elliptical disks, heating elements, temperature sensors and electronics for regulation and control. Outer concentric rings surround an inner disk. Disk and rings are made from good heat conductors, e.g. copper or silver. Between them are gaps that are filled with insulating material. Above a thin heating path, for each disk or ring, is a temperature sensor above which is a heat flow barrier, above which is a cooling reservoir.
