    摘要： A spinal fusion stimulator comprising an interbody fusion cage or other interbody fixation device adapted to be implanted in the intervertebral disc space of a patient's spine, the interbody fusion cage in the preferred embodiment having a hollow body with internal and external conductive surfaces. The stimulator includes a constant current generator connected to the interbody fusion cage and set to provide a DC current effective to produce a surface current density of at least 1 &mgr;A/cm2 in the interbody fusion cage when implanted.

    摘要： An apparatus includes an elongate body and an expandable member coupled to the elongate body. In one embodiment, the expandable member has a collapsed configuration, an unfolded configuration and an expanded configuration. The expandable member is configured to be percutaneously inserted into an interior portion of a bone structure when the expandable member is in the collapsed configuration. The expandable member is configured to exert a pressure in a vertical direction on a first portion of the bone structure in contact with the expandable member greater than a pressure exerted in a lateral direction on a second portion of the bone structure in contact with the expandable member when the expandable member transitions from the unfolded configuration to the expanded configuration.

    摘要： Devices and methods for performing a procedure within a spine are disclosed herein. In one embodiment, a method includes inserting an expandable member into an interior of a bone-related structure. The expandable member defines a first and second lumen. A medium is delivered through the first lumen and into the interior of the expandable member while within the interior of the bone-related structure. A filler material is delivered through the second lumen and into a cavity within the interior of the bone-related structure while the expandable member is disposed therein. An apparatus can include an expandable member that defines a first lumen in fluid communication with an interior volume of the expandable member, and a second lumen in fluid communication with an opening of the expandable member. The second lumen is configured to communicate a filler material through the opening and into an interior cavity of a bone-related structure.
