  • Patent number: 5827264
    Abstract: A apparatus and method for controlling an apparatus for removing tissue from the eye performs various types of corrections using a relatively large beam, but oscillating, or dithering, that being to prevent reinforcing ridges from being formed during the tissue removal process. Further, various types of correction, such as hyperopia and astigmatism correction, are performed using a large beam that is scanned over the area to be ablated using overlapping shots. Further, the epithelium in the area to be treated is removed using an infrared fluorescent dye to dye the epithelium, and then observing the fluorescent patterns from the epithelium area to be removed. Once a certain area is no longer fluorescent after laser shots, smaller shots are then applied, selectively removing the epithelium from the remaining regions. Again, the fluorescence patterns are observed, and the process is repeated until no epithelium remains.

  • Patent number: 5776200
    Abstract: The method of implanting a femoral and a tibial knee prosthesis and instruments for surgically implanting the femoral and tibial prosthesis component as disclosed. The method includes the formation of a plurality of surgical cuts on the patient's distal femur. A trial tibial prosthesis is then fitted to the surgically prepared distal femur. The trial prosthesis has a femoral articulating surface and a non-articulating surface that fits the patient's distal femur at the surgical cuts. A surgeon then forms a transverse cut on the patient's proximal tibia. The surgeon places a tibial trial prosthesis on the patient's proximal tibia, the trial prosthesis including a tibial trial stem that fits the patient's intramedullary canal, a tibial trial metallic tray or plate, and a plastic trial insert that fits the tibial tray or plate. The plastic insert includes a tibial articulating surface that can articulate with the femoral articulating surface.

  • Patent number: 5435728
    Abstract: A multi-functional therapeutic workstation which can simulate a multitude of job tasks. The workstation kit includes five panel designs, right angled elbows, nuts and bolts, and can be assembled into a variety of modules requiring the exercise of varying levels of cognitive and motor skills. Depending upon the position of the patient relative to the workstation kit, and the module that the patient is required to construct, the assembly rehabilitates both muscles as well as neurological pathways.

  • Patent number: 5271725
    Abstract: Apparatus and method for pumping fluids from horizontal wells with a dip tube used without requiring a packer in the well. Gas is separated from the liquid phase ahead of the pump to avoid slug flow of gas into the pump. This increases the amount of oil that can be pumped from the well by avoiding shutdowns resulting from gas-locking of the pump.

  • Patent number: RE34560
    Abstract: A plastic or like material liner inserted within a fabric type bulk bag so that the liner is secured in position within the bag with an adhering means along substantially the outer surface of the liner for adhering to the inner most surface of the bulk bag at strategic points, and a second adhering means for adhering the lower portion of the bulk bag to the liner at substantially the point of exit of bulk contained within the bag, so that release bulk from a lower spout would not tend to dislodge the liner from its lined position within the bag.
