Abstract

An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.

Claims (14)

1. A system for treating a vertebral disc, comprising:

a delivery cannula having a distal end portion for insertion into an intervertebral disc space;

a generally elongated implant having a longitudinal axis and a plurality of slots spaced along the longitudinal axis, wherein the slots are located along a side of the elongated implant and extend through upper and lower surfaces of the elongated implant;

the elongated implant being configurable into a first generally linear configuration for advancement through the delivery cannula and into the intervertebral disc space, the elongated implant being configurable into a second configuration in-situ as the elongated implant is delivered into the intervertebral disc space;

when in the second configuration, the elongated implant curves relative to the longitudinal axis to extend substantially 360 degrees, and defines a support structure having an inner side and an outer side with the slots of the elongated implant being located along the inner side, the support structure having an anterior portion and a posterior portion wherein the anterior portion has a greater height than the posterior portion.

2. The system of claim 1 in which the second configuration comprises a generally circular shape.

3. The system of claim 1 in which the support structure is configured to support superior and inferior vertebral bodies adjacent to the intervertebral disc space.

4. A system for treating a vertebral disc, comprising:

a delivery cannula having a distal end portion for insertion into an intervertebral disc space;

a generally elongated implant having a longitudinal axis and a plurality of slots spaced along the longitudinal axis, wherein the slots are located along a side of the elongated implant and extend through an upper surface of the elongated implant;

the elongated implant being configurable into a first generally linear configuration for advancement through the delivery cannula and into the intervertebral disc space, the elongated implant being configurable into a second configuration in-situ as the elongated implant is delivered into the intervertebral disc space;

when in the second configuration, the elongated implant curves relative to the longitudinal axis to extend substantially 360 degrees, and defines a support structure having an inner side and an outer side with the slots of the elongated implant being located along the inner side, the support structure having an anterior portion and a posterior portion wherein the anterior portion has a greater height than the posterior portion.

5. The system of claim 4 in which the second configuration comprises a generally circular shape.

6. The system of claim 4 in which the support structure is configured to support superior and inferior vertebral bodies adjacent to the intervertebral disc space.
