A flexible chain implant for insertion into an interior volume of a vertebral body. The implant may be implanted in an insertion position for sliding through a cannula and is flexible for packing into the interior volume in an implanted configuration. The implant randomly separates in the implanted configuration. The implant includes a top member and a bottom member, wherein the top and bottom members are coupled to one another at a coupled portion. The top and bottom members preferably each include an inner surface such that the inner surfaces include a plurality of alternating projections and recesses so that the projections are received within the recesses in an insertion position. Alternatively, the implant may include a plurality of substantially non-flexible bodies and a plurality of substantially flexible links interconnecting the bodies. The non-flexible bodies include a plurality of facets and/or abutment surfaces.

Flexible chain implants and instrumentation

Implants and methods for augmentation of the disc space between two vertebral bodies to treat disease or abnormal pathology conditions in spinal applications. The implant includes a chain of biocompatible material suitable for insertion into a disc space between two adjacent vertebral bodies in a patient's spinal column, wherein the spinal disc space has a transverse plane. The chain comprises a plurality of adjacent bodies having a height configured to reside within the disc space between two adjacent vertebral bodies and a length configured to reside in the disc space between two adjacent vertebral bodies when the chain is curved in an orientation substantially along the transverse plane of the spinal disc space.

An intervertebral spacer implant () is provided with a retention mechanism () to help alleviate expulsion and movement of the implant when placed in the spine while providing an implant that is easier to insert in the spine. In one embodiment the retention mechanism comprises a keel on at least one of the inferior or superior faces of the spacer implant preferably extending in an anterior-posterior direction. In another embodiment the implant comprises a spacer () and a plate (), the plate comprising a supplemental or alternative retention mechanism. In one embodiment the retention mechanism comprises one or more holes () in the anterior end of the plate. In yet another embodiment, the retention mechanism comprises one or more blades that are in a first position when inserted and are preferably rotated to a second position that engages the superior and inferior vertebrae.

Embodiments described include devices and methods for forming a porous polymer material. Devices disclosed and formed using the methods described a spacer for spinal fusion, craniomaxillofacial (CMF) structures, and other structures for tissue implants.

Porous biocompatible polymer material and methods

Implants and methods for augmentation, preferably by minimally invasive procedures and means, of body tissue, including in some embodiments repositioning of body tissue, for example, bone and, preferably vertebrae are described. The implant may comprise one or more chain linked bodies inserted into the interior of body tissue. As linked bodies are inserted into body tissue, they may fill a central portion thereof and for example in bone can push against the inner sides of the cortical exterior surface layer, for example the end plates of a vertebral body, thereby providing structural support and tending to restore the body tissue to its original or desired treatment height. A bone cement or other filler can be added to further augment and stabilize the body tissue. The preferred implant comprises a single flexible monolithic chain formed of allograft cortical bone having a plurality of substantially non-flexible bodies connected by substantially flexible links.

An intervertebral implant for fusing vertebrae is disclosed. The implant may have a body with curved, posterior and anterior faces separated by two narrow implant ends, superior and inferior faces having a plurality of undulating surfaces for contacting vertebral endplates, and at least one depression in the anterior or posterior face for engagement by an insertion tool. The implant may also have one or more vertical through-channels extending through the implant from the superior face to the inferior face, a chamfer on the superior and inferior surfaces at one of the narrow implant ends, and/or a beveled edge along a perimeter of the superior and inferior faces. The implant configuration facilitates transforaminal insertion of the implant into a symmetric position about the midline of the spine so that a single implant provides balanced support to the spinal column. The implant may be formed of a plurality of interconnecting bodies assembled to form a single unit. An implantation kit and method are also disclosed.
