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.

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.

Abstract: A Roman shade having a plurality of rearwardly extending vertically spaced horizontal pleats uses plastic retaining means adhesively bonded to the outer surfaces of the pleats and eyelets to precisely and durably maintain the pleats. The shade includes bodies of flexible facing and backing materials integrally segmented by folding portions of the material into pleat segments to form the pleats. Plastic strips having vertically aligned openings are adhesively secured to the outside surfaces of the pleats and interconnected by eyelets extending through the openings. Engaging surfaces of the eyelets engage the plastic strips further securing strips to the pleat outer surfaces. Edge borders of facing and backing material formed of back folded edge portions of said facing and backing material adhesively secured to itself, combined with disclosed pleat design, obviate need for sewing during construction.
