  • Patent number: 8845692
    Abstract: This invention relates to a orthopedic implant that comprises a shape memory polymeric material. The orthopedic implant can be fabricated or molded in a desired configuration selected to provide support or tension to bony structures. Examples of implantable devices include spinal rods, bone plates, and bone fixation cords. The orthopedic implant can be deformed to a second configuration different from the first configuration either prior to implantation or after implantation. When desired, the shape memory polymeric material can be induced to revert to it original molded configuration. This can compress the attached bony structure and/or promote arthrodesis.

  • Patent number: 8834528
    Abstract: A fixation device expands the spinal canal through osteotomies of the dorsal spinal elements (e.g lamina). Fixation is established to the dorsal vertebral elements (e.g. spinous process or lamina), with connection to a fixation device on each side of respective osteotomies. A distracting mechanism dorsally translates the fixated dorsal vertebral elements to expand the spinal canal. The fixation device allows secure fixation of the vertebra in the expanded state to promote bony healing across the osteotomy site. The fixation device can include a dorsal vertebral device (e.g., a transosseous fixation member placed through the spinous process) connected to a vertebral fixation device (e.g., bone screw or rod) by a connecting device with distracting mechanism. The connecting device spans the respective osteotomy, includes the distracting mechanism, and translates (lifts) the dorsal vertebral device from the vertebral fixation device in a dorsal direction to promote spinal canal expansion.

  • Patent number: 8814867
    Abstract: Expanding a spinal canal by drilling a cylindrical passage in each pedicle of a vertebra, making a circumferential pedicle cut (osteotomy) through each pedicle from within the passage, separating each pedicle cut by inserting an implant into the passage to distract the pedicle cut (i.e., lengthen the pedicle) to expand the spinal canal, and securing each pedicle cut, allowing the vertebra to heal with the spinal canal expanded. The implant can include an outer sleeve, an inner bolt, and expandable flanges. The outer sleeve includes an upper and a lower portion, with the expandable flanges therein. Rotation of the inner bolt causes the upper and lower portions of the outer sleeve to separate, causing the pedicle cut to widen and the expandable flanges to radially extend into and stabilize the widened pedicle cut for expansion of the spinal canal.
