  • Publication number: 20120143339
    Abstract: Devices and methods are disclosed for expanding a spinal canal. An implantable device having a shaft with a first cross-sectional dimension distinct from a second cross-sectional dimension can be inserted into an opening in a lamina and rotated 90 degrees to hinge the lamina away from the spinal canal. The implant can have one or more radiused edges, a bulleted tip, one or more lateral extensions for fastening the implantable device to bone, one or more hinged lateral extensions, one or more arcuate protrusions for biting into adjacent bone, an enlarged proximal head to prevent over-insertion, and/or a sleeve disposed therearound to reduce friction. Various embodiments of an insertion apparatus that can be selectively coupled to the implantable device are also disclosed, along with methods of expanding a spinal canal in minimally-invasive procedures using an implantable device and/or an insertion apparatus.

  • Patent number: 8097037
    Abstract: Method and devices are provided for correction of spinal deformities. The methods and devices are particularly useful for correcting an abnormal curvature of the spine. In one exemplary embodiment, the methods and devices provide a spinal implant that can include a wedged-shape configuration. The wedged implant can be interposed between adjacent vertebrae that form part of an abnormal spinal curvature, thereby realigning the vertebrae and restoring the normal curvature to the spine.

  • Publication number: 20110077688
    Abstract: Spinal anchoring methods and devices are provided that are effective to correct spinal deformities while allowing some flexibility to the spinal. In particular, the methods and devices allow a spinal fixation element to mate to several adjacent vertebrae to maintain the vertebrae at a fixed distance relative to one another, yet to allow the orientation of each vertebrae relative to the fixation element to adjust as the orientation of the patient's spine changes.

  • Patent number: 7655010
    Abstract: An intervertebral fusion device includes a body having a proximal portion along a major axis of the body and a distal portion along the major axis, and supporting means at the distal portion. The supporting means supports vertebrae in a distracted position while the vertebrae fuse. At least one of the body and the supporting means has a height distinct from a width, whereby the body or supporting means can distract vertebrae, between which the body or the supporting means has been placed, by rotation of the body or the supporting means about the major axis. A method of fusing vertebrae includes the steps of inserting between two vertebrae an intervertebral fusion device and rotating the body or the supporting means, whereby the vertebrae are supported in a distracted position while the vertebrae fuse.

  • Patent number: 7524335
    Abstract: A fiber-reinforced, polymeric implant material useful for tissue engineering, and method of making same are provided. The fibers are preferably aligned predominantly parallel to each other, but may also be aligned in a single plane. The implant material comprises a polymeric matrix, preferably a biodegradable matrix, having fibers substantially uniformly distributed therein. Inorganic particles may also be included in the implant material. In preferred embodiments, porous tissue scaffolds are provided which facilitate regeneration of load-bearing tissues such as articular cartilage and bone. Non-porous fiber-reinforced implant materials are also provided herein useful as permanent implants for load-bearing sites.
