    Abstract: 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.

    Abstract: Embodiments of the present disclosure relate to 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 disclosure 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.

    Abstract: The disclosure provides a tissue removal device including customizable tips. The tissue removal device may include an outer shaft and a threaded shaft. One aspect of disclosure may include a shaft cutting tool that emerges from the end of the outer shaft. Another aspect of the disclosure may include a flexible cutting blade extending from the threaded shaft. Threaded shaft may be driven by a driving mechanism in order to provide an auger-like suction mechanism to facilitate the transfer of removed tissue to a collection chamber that is coupled to the outer shaft and the threaded shaft.

    Abstract: A tissue removal device including customizable tips and method of use thereof. The tissue removal device may include an outer shaft having a removable tip attached to the outer shaft and a rotatable inner shaft extending through the outer shaft and having a rotatable cutting portion extending from the inner shaft. Disc material may be cut and removed from a surgical area using an auger-like and/or suction mechanism to facilitate the transfer of removed tissue away from the surgical area.
