An expansion member for distributing graft material through a cage and into an intervertebral space is provided. The expansion member has a central beam with an entry port in fluid communication with an exit port for distribution of the graft material. The central beam is inserted into a cage having a reversible collapse from an expanded state into a collapsed state, the expanded state forming a graft distribution window. The expanded state, for example, can be configured to open the graft distribution window which at least substantially closes upon the reversible collapse.

Distributing graft material from an expandable cage

Mechanical modifications to a spinal rod that will enable the rod to accept various coating technologies in such a way that the spinal construct's biomechanical performance is not compromised. These modifications preserve construct biomechanics in the presence of a coating and increase the bactericidal payload of an anti-infective spinal rod coating.

Anti-infective orthopedic implant

Dual coil ablation systems are provided. Methods of using the systems to ablate tissue are also provided. The dual coil ablation systems can include a first guide needle and a second guide needle, and the methods can include securing the tissue and guiding the dual coil ablation system into the tissue for the ablation, the securing and the guiding facilitated by the first guide needle and the second guide needle. The dual coil ablation systems can also include a phase-offset between the coils to achieve a significant and surprising enhancement to the energy density provided by the systems, and the uniformity of ablation provided by the methods.

Ablation system with impedance navigation

A staged expansion of an intervertebral scaffolding system is provided, and also include a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

Staged laterovertical expansion

An intervertebral scaffolding system is provided having a rigid central beam and a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state.

Expandable scaffolding with a rigid, central beam

Ablation systems are provided. Methods of using the systems to ablate tissue are also provided. The ablation systems can include a first guide needle and a second guide needle, and the methods can include securing the tissue and guiding the ablation system into the tissue for the ablation, the securing and the guiding facilitated by the first guide needle and the second guide needle. The dual coil ablation systems can also include a phase-offset between the coils to achieve a significant and surprising enhancement to the energy density provided by the systems, and the uniformity of ablation provided by the methods.

Guided ablation devices

An intervertebral scaffolding system is provided having a central beam having a proximal portion having an end, a grafting portion having a top and a bottom, a distal portion having a end, a central beam axis, a graft distribution channel having an entry port at the end of the proximal portion, a top exit port at the top of the grafting portion, and a bottom exit port at the bottom of the grafting portion. These systems can also include a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

Angled, rigid intervertebral scaffolding

Dual coil ablation devices

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.

Intervertebral scaffolding system

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.

Facet fixation and fusion screw and washer assembly and method of use

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. After fixing the trajectory guide, instruments can be inserted along the trajectory through the path defined by the trajectory guide.
