Patent ID: 7320686

Claim:
A device for distracting two adjacent vertebral bodies defining a disc space therebetween and delivering a flowable material into the disc space, comprising: a) a body comprising: i) a proximal portion, ii) a distal portion comprising a shape adapted to distract the disc space, wherein the shape adapted to distract has a width and a height, wherein the width is greater than the height, wherein the shape adapted to distract is adapted to distract upon insertion into the disc space and then rotation in the disc space, and wherein the shape adapted to distract has an upper bearing surface and a lower bearing surface, and wherein the upper and lower surfaces define a non-zero angle of between about 5 and about 15 degrees to provide lordosis when inserted posteriorly, and iii) a first longitudinal bore extending through the body and defining a first outlet in the distal portion opening onto the disc space, wherein the bore further defines an injection port in the proximal portion of the body, and b) an injection device filled with a flowable material selected from the group consisting of an in-situ curable liquid and a gel having a port attached to the injection port.
