A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.

An expandable fusion device may include a first endplate and a second endplate. The expandable fusion device may also include first and second ramps configured to mate with both the first and second endplates. The first ramp may include a mating feature having a first angle relative to a vertical axis, and the second ramp may include a mating feature having a second angle relative to the vertical axis such that the first angle is different from the second angle. In particular, the first and second ramps may be configured to provide for symmetrical expansion of the first and second endplates.

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 present disclosure is directed to an expandable medical implant for the repair of cranium defects in adolescent patients. The implants of the present disclosure can include a plurality of interconnected links that are movable with respect to each other as the underlying cranium grows and expands.

A bone structural device including a plurality of bone structural segments, wherein adjacent bone structural segments are pivotally connected to one another about a pivot axis, and the bone structural segments are expandable in height, which is in a direction generally parallel to the pivot axis.

A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.

A spinal joint distraction system for treating a facet joint including articular surfaces having a contour is disclosed and may include a delivery device including a generally tubular structure adapted to engage a facet joint, an implant adapted to be delivered through the delivery device and into the facet joint, the implant comprising two members arranged in opposed position, and an implant distractor comprising a generally elongate member adapted to advance between the two members of the implant causing separation of the members and distraction of the facet joint, wherein the implant is adapted to conform to the shape of the implant distractor and/or the articular surfaces of the facet upon being delivered to the facet joint. Several embodiments of a system, several embodiments of an implant, and several methods are disclosed including a method for interbody fusion.

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 an exemplary embodiment, the present invention provides an intervertebral implant. The intervertebral implant may be configured to transition from a collapsed configuration having a first height and a first width to an expanded configuration having a second height and a second width.

An expandable intervertebral spacer system having a top plate and a bottom plate forming a cage. The top, bottom, and sides of the cage have openings to receive bone graft material. At least one ramp extends into the cage from the top plate or bottom plate. The top plate and bottom plate are connected together at the proximal end of the cage at a hinge. The cage is expanded by inserting a pushrod into the proximal end of the cage against the ramp and forcing the top and bottom plates apart at a desired angle. A locking mechanism at the distal end of the cage locks the plates apart using a ratchet-like mechanism in which a torsion spring biases a movable post against a stationary post, such that the saw teeth of the movable post and stationary post cooperate to lock the top and bottom plates apart.

A method of placing an implant for intervertebral fusion between adjacent vertebral bodies in a patient includes inserting the implant in a space between the adjacent vertebral bodies such that both a first intervertebral spacer body and a second intervertebral spacer body contact each of the adjacent vertebral bodies. The first intervertebral spacer body is spaced apart from the second intervertebral spacer body. An expandable container portion of the implant disposed between the first intervertebral spacer body and the second intervertebral spacer body is filled with fill material such that the expandable container expands to contact each of the adjacent vertebral bodies.
