Fixation device and method

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...

AI Technical Summary

Benefits of technology

[0011]The device can be less invasive than typical existing devices. For example, the device can be in a compacted (i.e., small) configuration when inserted into a patient and transformed into an expanded (i.e., large) configuration when positioned at the target site. For example, the device can be expanded when the device is between the inferior and superior vertebral body surfaces. The device can create less soft tissue (e.g., bone) disruption than a typical fusion system. The device in an expanded configuration can improve anchoring within the joint, structural stability, and create an environment for bone healing and growth leading to fusion between adjacent vertebrae.

Problems solved by technology

Other ailments of the spine result in degeneration of the spinal disc in the intervertebral space between the vertebral bodies.

In either case, disc degeneration can cause pain and other complications.

This can relieve pain in the short term, but also often increases the risk of long-term problems and can result in motor and sensory deficiencies resulting from the surgery.
