  • Publication number: 20100286778
    Abstract: A textile-based surgical implant that can be inserted through any number of suitable surgical approaches, including but not limited to lateral, anterior, anterior-lateral, posterolateral, and/or posterior approaches. When applied to spine surgery and inserted into an intervertebral disc space, the implant restores the normal height of the intervertebral disc space, while advantageously preserving the natural motion of the spine. The textile construction of the implant is beneficial because it is generally compliant and thereby restores and/or improves spinal motion. The compliant nature of the textile-based implant provides the required flexibility and elasticity to advantageously support physiological movements, as opposed to fusion surgery which forms a boney bridge between adjacent vertebral bodies.

  • Patent number: 7708776
    Abstract: An improved total disc replacement system and related methods, wherein a pair of anchor plates, each adapted to engage a vertebral body, and a translating internal member are provided. The translating internal member boasts the ability to move or translate between the anchor plates without compromising the conformity of the interface between the translating internal member and the anchor plates. In a significant aspect, the anchor plates may be locked in place relative to one another after implantation to effect fusion between the vertebral bodies.

  • Patent number: 7618423
    Abstract: A system and associated methods for performing spinal fusion, involving the use of a graft holder assembly, a locking assembly, and a pair of bone graft implants to simultaneously introduce the bone graft implants into a disc space to thereafter effect spinal fusion.
