  • Publication number: 20040143270
    Abstract: This invention relates to tools for preparing vertebral bodies in the spine for the implantation of an artificial vertebral disk replacement and related method. A first tool is disclosed that prepares the vertebral bodies for implantation by cutting offset channels in the vertebral bodies. The second tool holds two plates of the implant during the implantation process. This invention also relates to an artificial vertebral disk replacement, a method of operation, and a method of implanting.

  • Publication number: 20040138750
    Abstract: The present invention is directed to a device that can be placed between two vertebrae. The implant is characterized by having a first plate and a second plate with a spacer therebetween. The spacer fits within cavities on each of the first and second plate.

  • Publication number: 20040138749
    Abstract: An artificial vertebral disk replacement implant is disclosed along with its method of operation and a method of implanting. The implant has first and second plates that each mate with a vertebral body. Each plate has one side for mating with a vertebral body. The first plate has a socket on one side, and the second plate has an elongated ball on one side. The ball of the first plate and the socket of the second plate form a ball-and-socket joint when the two plates are in contact with each other. The implant achieves a range of motion equivalent to a natural range of motion.

  • Publication number: 20040097931
    Abstract: The present invention is an implant for the lumbosacral region of the spine. The implant alleviates pain and increases lumbosacral stability while being minimally invasive. The beam of the implant engages the spinous process of the L5 vertebrae to spread the mechanical load from the vertebrae through the device.

  • Patent number: 6652527
    Abstract: The implant device is a minimally invasive device for assisting in the fusing together of vertebral bodies of the spine. The implant device immobilizes the vertebral bodies by immobilizing the respective spinous process extending from the vertebral body. The implant device has at least one spacer and hook to immobilize adjacent spinous processes. The spacer and hook are fastened to connection rods. Each connection rod can individually traverse through a range of motion, allowing each hook to engage the respective spinous process.

  • Patent number: 6345577
    Abstract: Propellant compositions are coated with an energetic deterrent coating which reduces the burning rate at the surface of the propellant grain and causes the propellant to burn progressively. The use of energetic materials, that are slightly soluble in the coating solvent, improve the burning properties of the propellant without decreasing the chemical energy.
