  • Patent number: 5364396
    Abstract: An implantable bone distraction device and method of using the device are disclosed. The device includes spaced first and second low profile blocks for subcutaneous implantation and attachment to osteotomically separated bone sections. The first block defines a drive chamber bore while the second block defines a threaded bore. A rotatable drive rod having a first end is received in the drive chamber bore of the first block. The rotatable drive rod's other end is threadably received in the threaded bore of the second block. The device further includes drive rod actuator located in the drive chamber bore for cooperating with the first end of the drive rod to rotate the drive rod so that one can adjust the depth to which the rod's threaded end is received in the threaded bore of the second block. This enables one to adjust the spacing between the first and second blocks, thereby enabling one to controllably distract the separated bone sections to enhance bone growth therebetween.

  • 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.

  • Patent number: 5350435
    Abstract: The present invention provides a soil fertilization method which includes a process for producing a fertilyzer by-product from an ammonia filtering media. The method includes the steps of providing a filter media containing phosphoric acid soaked particles. In addition, the method includes providing ammonia laden air. The ammonia laden air is passed through the filter media to remove ammonia from the air which is removed by a chemical reaction which converts the phosphoric acid soaked wood particles to ammonium phosphate coated wood particles. After substantially all of the wood particles are converted to ammonium phosphate wood particles, the filter media is collected and then applied to soil to fertilize and build the soil.
