Methods and apparatus are disclosed for distracting tissue. The devices and methods may include insertion of first and second elongated members into the space between two tissue layers, with an augmenting elongated member at least partially inserted therebetween to form a distraction device between the tissues to be distracted. At least one of the first and second elongated members may be formed of a flexible core member with a plurality of rigid veneer members spaced along the length of the core member. At least one of the elongated members may include a shaping member that automatically moves from a generally linear configuration to a generally less linear configuration. A deployment catheter may include a deformable distal end to allow augmentation of the tissue distraction device during implantation. An injection aid may be provided for introducing a filler material into an interior defined by a deployed tissue distraction device.
A61B 17/88 - Methods or means for implanting or extracting internal fixation devices

Devices for fixing interbody fusion devices to bone by helically or corkscrew-shaped elements are provided. Methods for surgically implanting an interbody fusion device using helically-shaped fixation wire are provided.
A clip-on reducer tool assembly for seating a spinal fixation rod in a rod receiving implant, the tool assembly has an outer sleeve. The outer sleeve has a proximal end with a cylindrical portion having a threaded opening, a first leg extension extending therefrom to a distal end, and a second leg extension joined to the first leg extension at an intermediate location between the distal end and proximal end. The second leg extension extends from the distal end toward the proximal end to a lever end spaced from the cylindrical portion. The leg extensions at the distal end have grasping members to engage an outer surface of a rod receiving implant and a fulcrum proximally located near the intermediate location configured to enlarge the space between the leg extension at the distal end as the lever end is depressed inwardly relative to a longitudinal axis of the outer sleeve.
An expandable interbody device for placement between adjacent vertebrae having an upper structure, a lower structure and a screw mechanism, wherein actuation of the screw mechanism moves the upper and lower structures between a collapsed configuration and an expanded configuration. A deployment tool couples to the expandable interbody device for positioning the device between adjacent vertebrae, actuating the screw mechanism and delivering a material to a chamber of the expandable interbody device.
Devices and methods for protecting the neurovascular structures about the vertebral column are provided. One embodiment of the invention comprises a neuroprotective stent or device adapted for placement in an intervertebral foramen of a vertebral column and configured to resist compression or impingement from surrounding structures or forces. The stent or device may further comprise a flange or hinge region to facilitate attachment of the device to the vertebrae or to facilitate insertion of the device in the foramen, respectively.

In some embodiments, a device for reinforcement of a facet joint is provided. The device comprises a lumen configured to receive a fastener member. In some embodiments, a second segment comprises a second lumen configured to receive a fastener member or fastener. In some embodiments, kits are provided with a fastener member and a facet reinforcement device. Methods are also provided for treating a spine. In some embodiments, the fastener member is placed through both articular processes of a facet joint and a facet reinforcement device.
Methods and devices are disclosed for treating the vertebral column. An implant for treating the spine is provided comprising at least two articulations between the spacer and the bone facing surface of the fixation plate. Another implant for treating the spine is also provided, comprising two or more fixation plates attached to a spacer with two or more articulations, wherein the fixation plates are independently movable.

A modular tulip assembly has a rod receiving tulip and a saddle. The saddle is interlockingly held inside a distal portion of the tulip. The saddle has an external locking groove or recess. The tulip has a locking projection. The locking projection is positioned into the external locking groove or recess and holds the saddle in a pre-loaded unlocked state ready to be pushed onto a head of an implanted bone screw. Upon receiving the head of the bone screw, the saddle can be moved distally relative to the tulip to a locked state by moving the locking groove or recess distally past the locking projection to where the proximal end of the saddle is past abutting the locking projection.
