11426290 · 2022-08-30 · ·

An implant includes a first plate and a second plate, a first wedge member and a second wedge member spaced from the first wedge member that couple the first and second plates together. The first and second wedge members configured to translate along the first and second plates from a first contracted configuration into a second expanded configuration. The implant includes an actuation member coupled to the first wedge member and the second wedge member. The actuating member defines a flange extending toward the first and second plates. The actuation member configured to move the first and second wedge members from the first contracted configuration into the second expanded configuration so that the first and second plates separate from each other.

Expandable support device and method of use

An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone or vertebral discs. The device can have multiple flat sides that remain flat during expansion. A method of repairing tissue is also disclosed. Devices and methods for adjusting (e.g., removing, repositioning, resizing) deployed orthopedic expandable support devices are also disclosed. The expandable support devices can be engaged by an engagement device. The engagement device can longitudinally expand the expandable support device. The expandable support device can be longitudinally expanded until the expandable support device is substantially in a pre-deployed configuration. The expandable support device can be then be physically translated and/or rotated.

Methods and apparatus for performing spine surgery

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.

EXPANDABLE SUPPORT DEVICE AND METHOD OF USE

An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone or vertebral discs. A method of repairing tissue is also disclosed. The device and method can be used to treat compression fractures. The compression fractures can be in the spine. The device can be deployed by compressing the device longitudinally resulting in radial expansion.

VERTEBRAL JOINT IMPLANTS AND DELIVERY TOOLS

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.

Intervertebral spacer with ramped integral expansion mechanism and stepped locking mechanism

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.

Spinal fusion device with staged expansion
11331197 · 2022-05-17 · ·

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. The fusion device described herein is capable of being installed inside an intervertebral disc space at a minimum to no distraction height and for a fusion device capable of maintaining a normal distance between adjacent vertebral bodies when implanted.

EXPANDABLE INTERVERTEBRAL IMPLANT

An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.
