Abstract

Official abstract text for this publication.

An expandable interbody fusion device and an associated instrument for inserting the device into an intervertebral disc space, expanding the device and for use in delivering graft material into the device once expanded in the disc space. The device is small enough to fit through Kambin's triangle yet is capable of expanding both in the vertical direction to accommodate spinal lordosis and in the lateral direction to provide sufficient structural support for opposing vertebral bodies laterally within the disc space. A process of forming textured top and bottom surfaces of the device by initially laser ablating each surface with a nano-second pulsed laser followed by laser ablating those surfaces with a femto-second pulsed laser.

First claim

Opening claim text (preview).

What is claimed is: 1. An interbody fusion device comprising an expandable cage formed of titanium or titanium alloys, said cage comprising a top surface and an opposite bottom surface, a proximal end including a base, a plurality of flexible arms each attached to and projecting from a hinge point at said base toward a distal end of the cage, a hollow interior, and a moveable cage expansion wedge slidable within said hollow interior, wherein each arm is free and unattached to anoth…
