Abstract
A nucleus pulposus replacement is described that includes a containment balloon that can sequester synthetic and/or tissue engineered fill material(s) in the nucleus pulposus region of the IVD thus mitigating migration and expulsion of the fill materials. The containment balloon can be formed of a biocompatible material that includes the structural proteins elastin and collagen. The containment balloon is joined to a closure device that can be used to deliver a fill material, e.g., a hydrogel, to the interior of the containment balloon following implantation of the replacement device in the intervertebral disc area.
