    摘要： 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.

    摘要： Various methods and devices are provided for navigating through bone. In one embodiment, a bone navigation device is provided and includes a bone penetrating member configured to be implanted in bone and having at least one optical waveguide extending therethrough. The optical waveguide is adapted to illuminate tissue surrounding the device and to receive reflected/transmitted light from the tissue to determine the optical characteristics of the tissue, thus facilitating navigation through the tissue. At least one window can be formed in the bone penetrating member for allowing light from the at least one optical waveguide to illuminate the tissue, and for receiving the reflected light.
