<p>A spinal implant (30) having a series of sections or units (32) hinged together and a balloon (50) connected to at least some of the sections, the balloon having a curved configuration. The implant has a first delivery- configuration and a second curved placement configuration, wherein it has a more linear configuration in the first delivery configuration than in the second curved configuration. The implant assumes the first delivery- configuration during delivery to the disc space and maintains the curved configuration after placement within the disc space. The curved configuration can result from filling or expanding the balloon.</p> |
