  • Patent number: 7547318
    Abstract: A spinal fixation element is provided having a feature formed thereon that facilitates placement of the spinal fixation element through an access device, thus allowing the spinal fixation element to be positioned in relation to a spinal anchor that is coupled to the access device and that is implanted in a vertebra in a patient's spine. The feature also optionally facilitates placement of the spinal fixation element in relation to spinal anchors implanted in adjacent vertebrae. In particular, the spinal fixation element is adapted for use with an access device that has at least one slot or opening formed therein and having a width that is less than a width of the feature, thus preventing the feature from passing therethrough. The spinal fixation element can therefore be inserted through the access device, and a portion of the fixation element can be passed through the slot or opening in the access device while the feature is retained in the access device.

  • Publication number: 20090030421
    Abstract: A method and system for engaging an implant with a bone is disclosed. In one method incorporating principles of the invention, a bone is engaged with an implant by placing a first surface of an implant adjacent to a first bone portion, contacting the first bone portion with at least one first engagement member extending from the first surface, controlling an agitator to agitate the first surface of the implant and the at least one first engagement member, generating at least one first surface feature in the first bone portion with the agitated at least one first engagement member, stilling the first surface implant and the at least one first engagement member and settling the stilled at least one first engagement member into engagement with the at least one first surface feature.

  • Publication number: 20080255622
    Abstract: A spinal implant including a stabilization member coupled to an elongate member is herein provided. The implant can be configured for placement within a facet joint in an intra-facet or trans-facet configuration. Also, the implant can include a fusion-promoting bioactive material thereby providing a single device capable of spinal stabilization and/or fusion. Furthermore, a method of placing such an implant within a facet joint in an intra-facet or trans-facet orientation is hereby provided.

  • Publication number: 20070276406
    Abstract: Disclosed herein are methods and devices for distracting adjacent vertebrae during surgical procedures for implanting spinal prostheses. In an exemplary embodiment, a distractor is disclosed that maintains the empty space between adjacent vertebrae following a discectomy, and that can removably mate with other surgical instruments, such as, for example, a filler bar, an implanting tool, or a funnel. In other embodiments of the present invention a distractor is disclosed having various features to assist in implanting a spinal prosthesis, such as, for example, an angled distal end and/or an expandable paddle. In another embodiment of the present invention, an articulating inserter is disclosed. Moreover, various implants and funnels are also disclosed herein.

  • Publication number: 20070055291
    Abstract: A system for guiding an implant to an optimal placement within a patient includes a trajectory guide for guiding instruments along a selected trajectory and a trajectory fixation device for fixing the trajectory guide in a selected position. The trajectory guide defines a path configured to align with the selected trajectory. A movable support mounts the trajectory guide and selectively moves the trajectory guide to align the trajectory guide with the selected trajectory prior to fixing the trajectory guide in the selected position. The trajectory is aligned coarsely by hand, then the trajectory is aligned using a fine adjustment system. After fixing the trajectory guide, instruments can be inserted along the trajectory through the path defined by the trajectory guide.
