Embodiment Construction

[0037]A device 2 is disclosed that can be inserted into a target site 264 with the device 2 in a compressed or contracted (i.e., small) configuration. Once positioned in the deployment site, the device 2 can be transformed into an expanded (i.e., larger, bigger) configuration. The device 2 can be inserted and expanded in orthopedic target sites 264 for fixation and / or support. For example, the device 2 can be inserted and expanded over a guidewire between adjacent vertebral bodies.

[0038]FIG. 1 illustrates that the device 2 can have a first longitudinal end and a second longitudinal end along a longitudinal axis 4. The device 2 can have a bottom or plate 286 (bottom and base plate are used interchangeably) and a top plate 6. The base 138 or bottom plate 10 and top plate 6 can be or have plates 286, panels, struts 216 (e.g., legs), ports, cells 88, and combinations thereof. The base plate 10 and top plate 6 can be configured to be slidably attachable to the other. For example, the bas...

Abstract

An implantable orthopedic stability device is disclosed. The device can have a contracted and an expanded configuration. A method of using the device between adjacent vertebral body surfaces surfaces for support and / or fixation of either or both of the adjacent vertebrae is also disclosed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 12 / 617,663, filed Nov. 12, 2009, which claims the benefit of U.S. Provisional Application No. 61 / 113,691, filed on Nov. 12, 2008.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]Devices and methods for fixation of tissue are disclosed. More specifically, the devices and methods can be for inter body vertebral fusion of vertebrae or fusion of other bones to one another.[0004]2. Background of the Art[0005]A vertebroplasty device and method that eliminates or reduces the risks and complexity of the existing art is desired. A vertebroplasty device and method that may reduce or eliminate the need to inject a liquid directly into the compression fracture zone is also desired.[0006]Other ailments of the spine result in degeneration of the spinal disc in the intervertebral space between the vertebral bodies. These include degenerative disc disease and traumatic...
