Patent number: 5358503Abstract: An apparatus, for simultaneous or selective treatment of an area of the skin and adjacent subcutaneous structure of a patient utilizing photo energy and therapeutic heat, which includes a plurality of juxtaposed diodes. Each diode has a longitudinal axis and is capable of projecting a non-coherent cone of light which overlaps the cone of light from each juxtaposed diode so that the light completely covers the treatment area. A flexible pad or appliance holds the diodes in juxtaposed position with each other. Each is held in contact with the skin and has a longitudinal axis which is in substantially perpendicular relationship to the skin. A resistor heats each diode, which acts as a heat sink, so that the treatment area of the skin and the adjacent subcutaneous structure of the mammal receive light and thermal treatment simultaneously. An adjustable control varies the light intensity of the diodes and the amount of heat generated by the resistor in a selected and controlled manner.Type: GrantFiled: January 25, 1994Date of Patent: October 25, 1994Inventors: Dale E.
