Patent number: 11253170Abstract: Implementations described herein include surgical distraction devices having a distal movement assembly having a pusher plate comprising a first slot extending along a first axis disposed in a first side and a second slot extending along a second axis disposed in a second side thereof. The first axis is oriented at an angle of from about 60 to about 160 degrees from the second axis. The device further includes a first and second paddles, each paddle having a corresponding engagement mechanism for movably coupling the respective first or second paddle to the pusher plate when engaged in the respective slot. Rotational actuation of the proximal drive assembly causes proximal or distal movement of the pusher plate, causing the first and second engagement members to move relative to their respective slots, thereby moving the first paddle and the second paddle in opposing directions. Methods of using such surgical distraction devices to determine size of an intervertebral space are also described.Type: GrantFiled: December 13, 2019Date of Patent: February 22, 2022Assignee: Zimmer Biomet Spine, Inc.Inventors: Terry Ziemek, Susanne Duman, William Sandul, Samuel Jebsen

Patent number: 11065129Abstract: An expandable intervertebral fusion device is provided including a core, an upper endplate for contacting a first vertebral body and a lower endplate for contacting a second vertebral body. The expandable intervertebral fusion device is configurable in a first state, a second state and a third state. In the first state, the upper and lower endplates are generally planar to one another and define a first height. In the second state, the upper and lower endplates remain generally planar to one another and define a second height greater than the first height. In the third state, a lordotic angle is defined between the upper and lower end plates.Type: GrantFiled: April 3, 2019Date of Patent: July 20, 2021Assignee: Zimmer Biomet Spine, Inc.Inventor: William Sandul

Patent number: 10045800Abstract: The present invention provides spinous process implants and associated methods. In one aspect of the invention, the implant includes a first extension and a second extension. The first extension has a spacer extending from a medial lacing side along a longitudinal axis. The second extension has an aperture that slidingly receives the spacer. Accordingly, the second extension is moveable relative to the spacer along the longitudinal axis. The second extension includes a threaded bore in communication with the aperture. A set screw is threadably received in the threaded bore of the second extension. The set screw can be tightened against an outer surface of the spacer to lock the second extension in place relative to the longitudinal axis.Type: GrantFiled: September 29, 2016Date of Patent: August 14, 2018Assignee: Zimmer Biomet Spine, Inc.Inventors: Justin Taber, Patrick Hunt, Andrew Lamborne, Randall G. Mast, William Sandul, Dean Karahalios

Patent number: 9561060Abstract: The present invention provides spinous process implants and associated methods. In one aspect of the invention, the implant includes at least one extension with a superior lobe pivotally connected to an inferior lobe, such as by a hinge, to allow unfolding of the at least one extension from a folded position to an unfolded position. In certain aspects, the folding extension may include fasteners to facilitate engagement with the spinous processes to provide both a flexion stop as well as an extension stop. The fasteners may have corresponding bores to allow the fasteners to reside in the bores to provide a compact profile for implantation. In another aspect of the invention, the implant is introduced to the surgical site using a lateral or paramedian approach and associated tools to facilitate the same.Type: GrantFiled: December 31, 2013Date of Patent: February 7, 2017Assignee: Zimmer Biomet Spine, Inc.Inventors: Justin Taber, Patrick Hunt, Andrew Lamborne, Randall G.
