International Classification:
A61B 17/70, A61B 17/00, A61B 17/56, A61B 17/58
US Classification:
606151, 606103
Abstract:
An adaptable clamping mechanism for coupling an elongate spinal fixation element to a bone anchor is provided. A seat element and a clamp element of the adaptable clamping mechanism adapt to seat and clamp an elongate spinal fixation element whose longitudinal axis is non-perpendicular relative to the as central axis of the bone anchor. One or both of the seat element and the clamp element may adjust to an out-of-plane orientation of the elongate spinal fixation element by pivoting or rotating in one or more directions. One or both of the seat element and the clamp element may have a deformable portion configured to deform to the orientation of a surface of the elongate spinal fixation element. In addition, the seat element may be configured to provide tactile and/or auditory feedback to a surgeon when the seat element and the elongate spinal fixation element are in contact, facilitating proper positioning of the elongate spinal fixation element in the rod seat when using a minimally invasive rod-first surgical technique.

US Classification:
606246, 606279
Abstract:
A minimally invasive fixation system and installation method is provided. The system includes a rod having an anchor fixation head, an anchor system for anchoring the rod using the anchor fixation head, and a guide system configured to attach to the anchor fixation head of the rod for the insertion of the additional anchor systems. In one embodiment, a method for placing a spinal fixation element relative to a vertebra is provided. The method includes inserting the spinal fixation element relative to the vertebra; connecting the spinal fixation element to a first vertebra with a first anchor; manipulating the spinal fixation element relative to the first anchor to align the spinal fixation element with a second vertebra; fixing the position of the spinal fixation element relative to the first bone anchor; determining an anchor site on a second vertebra using a guide system connected to the spinal fixation element; inserting a second anchor at an anchor site on second vertebra; and connecting the second anchor to the spinal fixation element to fix the spinal fixation element relative to the first vertebra and second vertebra.

International Classification:
A61B 17/70
US Classification:
606264, 606278, 606301, 606305, 606308
Abstract:
A rod anchoring system including a bone anchor and a connector is provided. The connector of the rod anchoring system is configured to be inserted in one orientation and then transitioned to a second orientation to connect the rod to the anchor. The bone anchor includes a detachable extension shaft that acts as a guide for inserting the connector. In use, once the bone anchor has been implanted at a target site on a vertebra, the connector is placed onto the extension shaft and slid along its length in a first orientation to insert the connector. Once the connector is at the implant site, it is transitioned from the first orientation to the second orientation to connect the rod to the anchor.

Steven Craig Ludwig - Baltimore MD, US
International Classification:
A61B 17/88, A61B 17/70
US Classification:
606279, 606246
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.
