Spinal tissue distraction devices that include a member which has a pre-deployed configuration for insertion between tissue layers and a deployed configuration in which the member, by change of configuration, forms a support structure for separating and supporting layers of spinal tissue.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

A graft material injector device and method are disclosed. The injector device includes an elongated injector tube and a side loading aperture for receiving graft material. A graft material loader and a cover for the side loading aperture may optionally be included.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

An implantable orthopedic support device and methods of using the device are disclosed. The device can have rigid structural components that can translate longitudinally with respect to each other, and in so doing can change the vertical height of the device. The structural components can be driven by a drivescrew mechanism to change the vertical height of the device.

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.

Articulated instruments that include tools for disrupting and/or distracting tissue, and methods of using the same.
