  • Patent number: 7575600
    Abstract: The present disclosure is directed to an implant that can be placed between two vertebrae using a lateral, anterior or posterior insertion method. The implant is characterized by having a first endplate and a second endplate, both endplates having inner surfaces that oppose each other when anchored into opposing vertebral bodies. The inner surfaces give rise to two articulating elements, each articulating element including two compatible units that mate and allow motion of the spine, including flexion, extension, lateral motion and rotational movement.

  • Patent number: 7520899
    Abstract: The present invention is directed to an implant that can be placed between two adjacent vertebral bodies using a lateral insertion method. The implant is characterized as having a first end plate and a second end plate which a crossbar spacer therebetween. The crossbar spacer preferably fits within a channel on the inner surfaces of the first end plate and the second end plate, whereby the crossbar spacer allows pivots, twisting and/or rotational movement of the spine. The first end plate and the second end plate include a keel extending therefrom, whereby the keel traverses longitudinally between a first lateral side and a second opposed lateral side and is substantially perpendicular to the sagittal plane of the patient's spine.

  • Publication number: 20090093817
    Abstract: Systems and methods for injecting bone filler into a vertebra, wherein a spinous process and/or lamina can be strengthened by injecting the bone filler into the spinous process and/or lamina. An insertion device including a needle can be positioned proximal to the junction between the spinous process and the lamina of the vertebra when inserting the bone filler. Various embodiments of the needle and needle guide devices can be used to facilitate the process.

  • Patent number: 7510567
    Abstract: The invention provides a method of inserting a two piece implant into a patient. A first insertion device is connected to a first piece of the implant, and a second insertion device is connected to a second piece of the implant. Each piece of the implant is inserted with its associated insertion device. The inserted pieces are aligned relative to each other by mutual engagement of alignment structures of the insertion devices. The aligned pieces are connected to each other and the insertion devices are disengaged from the implant pieces.

  • Patent number: 7503935
    Abstract: An implant that can be placed between two vertebrae using a lateral insertion method is described. The implant is characterized by having a first end plate and a second end plate with a hemi-cylindrical spacer extending from the second end plate. The hemi-cylindrical spacer fits within a socket on the first end plate and allows for pivotal or rotational motion and also for twisting motion.

  • Patent number: 7497859
    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.

  • Patent number: 7481839
    Abstract: A device for implantation between interspinous processes made of bioresorbable materials is described. The implant has a spacer that can be placed between adjacent spinous processes to limit the movement of the vertebrae. Once inserted between interspinous processes, the implant acts to limit extension (backward bending) of the spine without inhibiting the flexion (forward bending) of the spinal column. The device is used as an adjunct to repair or regeneration of an intervertebral disk.

  • Patent number: 7473268
    Abstract: Insertion instruments and a main body assembly and a universal wing to be inserted are provided, along with methods of using these instruments for the insertion of the spinal implants in patients to relieve the symptoms of, for example, spinal stenosis, injuries, and degenerative diseases of the spine. The instruments are simply designed and can be disassembled, making cleaning and sterilization easy and convenient. The instruments are designed to engage with and disengage from spinal implants easily, and use of the instrument in spinal implant surgery can be carried out with minimal surgical intervention and does not require general anesthesia. The main body assembly and the universal wing are designed to conveniently be secured to the insertion instruments. In an alternative embodiment the instrument can be nested and at least one instrument can include a handle provided at an angle.
