  • Patent number: 6607550
    Abstract: A method for the reduction of sensory impairment due to peripheral neuropathy comprising placing an apparatus which provides photo-energy in proximity to the skin and/or subcutaneous structures suffering from sensory impairment, and irradiating the skin and/or subcutaneous structures with the apparatus with sufficient duration (total weeks of treatments), intensity (energy in Joules per treatment) and frequency (treatments per week) to reduce sensory) impairment.
    Type: Grant

  • Patent number: 5485807
    Abstract: A hand-held brush is provided for grooming. The brush comprises a body section and a head section connected therebetween. The body section includes two opposing half curved portions and a base portion. The head section includes two opposing half oval portions, first and second protruding ears, and a crown portion connecting the ears. The closed figure achieved by the combination of these elements results in the outline of any number of different types of animals. Attached to a bottom side of the brush are a plurality of cone shaped bristles. The brush is flexible such that the body and head sections flex independently and continuously along the surface of the animal being brushed. The bristles also substantially conform to the surface being brushed and are made of the same material as the body and head sections.

  • Patent number: 5358503
    Abstract: 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.
