Patent number: 11918482Abstract: An expandable interbody implant adapted for insertion at least into a disc space, between two adjacent vertebrae of a spine. An upper member and a lower member are pivotally connected at least by a drive link. A bone graft storage portion packed with a selected volume of bone growth material. A translational wall is provided between the bone graft storage portion and a trailing end of the implant. An actuator engages the bone graft storage portion, pushing it forward into engagement with the drive link, which pivots upward, moving the upper member upward away from the lower member. Upward movement of the upper member raises the translational wall to a position to assist in retention of the selected volume bone graft material within the hollow portion of the bone graft storage portion. Upward rotation of the drive link brings a face thereof into contact with a front of the bone graft storage portion, thereby retaining near constant volume of the bone graft material.Type: GrantFiled: June 14, 2021Date of Patent: March 5, 2024Assignee: WARSAW ORTHOPEDIC, INC.Inventors: Anthony J. Melkent, William D. Armstrong, Stanley T. Palmatier

Publication number: 20240008998Abstract: An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.Type: ApplicationFiled: August 31, 2023Publication date: January 11, 2024Inventors: Charles Branch, Charles Fisher, Mladen Djurasovic, Marcel Dvorak, Sigurd Berven, Anthony J. Melkent, Jonathan M. Dewey, Keith E. Miller, Adriaan J. Kuyler

Patent number: 11666459Abstract: Spinal implant trials are provided having various configurations and sizes that aid the selection of spinal implants having similar configurations and sizes. A surgeon during surgery can insert various configurations and sizes of the spinal implant trials into a disc space between two adjacent vertebral bodies of a patient to enable the selection of a spinal implant configured and sized to fit the patient's disc space. Fluoroscopic images can be used in aiding the selection of an appropriately configured and sized spinal implant corresponding to one of the spinal implant trials. The spinal implant trials include features that reveal on the fluoroscopic images whether the spinal implant trials are properly oriented and positioned in the disc space. As such, the selection of the configuration and size of the spinal implants can be made after it is determined that the spinal implant trials are properly oriented and positioned within the disc space.Type: GrantFiled: June 23, 2020Date of Patent: June 6, 2023Assignee: WARSAW ORTHOPEDIC, INC.Inventors: Jonathan M. Dewey, William D. Armstrong, Anthony J. Melkent
