  • Patent number: 8568452
    Abstract: The invention consists of disc replacement implant for the lumbar spine designed for insertion into the disc space via a posterior approach. The implant can be stabilized in the disc space by connection to the vertebra or can be connected to dynamic spinal stabilization device consisting of interconnected bullets nested in a spring nested in a woven sleeve. By controlling the limits of elongation and compression the device prevents movement beyond normal physiological limits. In the midrange of movement flexibility is allowed. A method for using the dynamic spinal stabilization device is also provided.
    Type: Grant

  • Patent number: 4784150
    Abstract: A surgical retractor instrument which incorporates therein a blood flow monitor. A surgical retractor system is disclosed for manipulation of living tissues and/or organs during diagnostic and/or surgical procedures, providing for the monitoring of the presence or absence of blood flow in the tissue adjacent thereto. The surgical retractor incorporates a surgical retractor blade, which can be of any conventional or desired design or physical shape, depending upon the intended use thereof. The pressure end of the retractor blade is designed with fiber optics for directing light (specifically IR) having predetermined spectral characteristics related to blood onto the adjacent tissues and/or organs. The retractor blade is also designed with receiving fiber optics for receiving light which is directed at and reflected from the tissues and/or organs.
