Devices and methods for treating one or more damaged, diseased, or traumatized portions of the spine, including intervertebral discs, to reduce or eliminate associated back pain. In one or more embodiments, the present invention relates to an expandable interbody spacer. The expandable interbody spacer may comprise a first jointed arm comprising a plurality of links pivotally coupled end to end. The expandable interbody spacer further may comprise a second jointed arm comprising a plurality of links pivotally coupled end to end. The first jointed arm and the second jointed arm may be interconnected at a proximal end of the expandable interbody spacer. The first jointed arm and the second jointed arm may be interconnected at a distal end of the expandable interbody spacer.

A device for performing a surgical procedure includes an elongated shaft extending between a proximal end and a distal end. The shaft includes an outer surface and an inner surface. An expandable member is disposed at the distal end of the shaft. The expandable member is configured to receive inflation material. At least one electrode is disposed with the inflatable member. Methods of use are disclosed.

The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.

A central inflatable distractor and a perimeter balloon are inserted into the disc space in uninflated configurations. The central inflatable distractor is then expanded, thereby distracting the vertebral endplates to the controlled height of the central inflatable distractor. The perimeter balloon is then inflated with a curable substance. The perimeter balloon expands as it is filled with the curable substance and conforms to the void remaining in the disc space around the central inflatable distractor, thereby creating a horseshoe shape. Once the flowable material in the perimeter balloon has cured, the central inflated distractor can be deflated and removed. The remaining void (or inner space) is then packed with graft for fusion.

Internal bone fixation devices and methods for using the devices for repairing a weakened or fractured bone are disclosed herein. A device for use in repairing a fractured bone includes a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, wherein the delivery catheter has an inner void for passage of at least one reinforcing material and an inner lumen for passage of a light source; a conformable member releasably engaging the distal end of the delivery catheter, wherein the conformable member moves from a deflated state to an inflated state when the at least one reinforcing material is delivered to the conformable member; and an adapter releasably engaging the proximal end of the delivery catheter for receiving the light source and the at least one reinforcing material.

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.

Apparatus and methods for bone fracture repair. The apparatus may include a structural support for positioning a first bone segment relative to a second bone segment. The apparatus may include an anchoring substrate. The anchoring substrate may be configured to compress the first bone segment to the second bone segment. The anchoring substrate may transmit tension from a distal bone segment anchor in the first bone segment to a proximal bone segment anchor in the second bone segment. The apparatus may be configured to be deployed percutaneously in an inner cavity of a bone. The apparatus may be installed in an open fracture. The apparatus may be expanded, self-expanding or configured for mechanically actuation. Some embodiments of the apparatus may include a central axis member that may be used in conjunction with expansion of one or both of the structural support and the anchoring substrate to configure the apparatus.

The present invention provides a spinal implant structure. The spinal implant structure comprises a first part, a second part and at least one expansion arm. The second part is disposed on the horizontal orientation of the first part and does not overlap with the first part. The diameter of the first part is larger than that of the second part. One end of the expansion arm is connected to the first part, and the other end of the expansion arm is free end. The expansion arm includes a supporting arm. One end of the supporting arm is connected to the expansion arm, and the other end is connected the second part. The support arm includes a plurality of structure weakness. When the distance between the first part and the second part changes, the support arm bends from the structure weakness, thereby the spinal implant structure is expanded.

A spinal implant comprises a body including an inner surface that defines a cavity. The inner surface includes a baffle. The body is disposable between a contracted configuration and an in vivo expandable configuration. Systems and methods are disclosed.

A surgical instrument includes a body having an actuator and being connectable with a pressurized fluid source. A first member is connected with the body and the fluid source. The first member is configured for connection with an implant disposable between a contracted configuration and an expanded configuration. A second member defines a cavity configured for disposal of the first member and the expandable implant. The second member is connected with the actuator for selective translation relative to the first member to position the implant in the contracted configuration. Systems, implants and methods are disclosed.
