Patent number: 11690728Abstract: An intervertebral implant component of an intervertebral implant includes an outer surface for engaging an adjacent vertebra and an inner surface. A keel extends from the outer surface and is designed to be disposed in a slot provided in the adjacent vertebra. This keel extends in a plane which is non-perpendicular to the outer surface; and preferably there are two of the keels extending from the outer surface which are preferably offset laterally from one another. In another embodiment, an anterior shelf is provided at an anterior end of the outer surface, and this anterior shelf extends vertically away from the inner surface in order to help prevent bone growth from the adjacent vertebra towards the inner surface. Further in accordance with disclosed embodiments, various materials, shapes and forms of construction of the component and/or keel provide various benefits.Type: GrantFiled: March 9, 2020Date of Patent: July 4, 2023Assignee: CENTINEL SPINE, LLCInventors: Rudolf Bertagnoli, Shaun Hanson, Joern Richter, John Paul Furda, Fabian Haller, David Gerber, Roger Berger, Stefanie Kaufmann

Patent number: 11517445Abstract: Spinal implants that are configured for a minimally invasive approach to a patient's intervertebral disc space, optimized to avoid blood vessels and nervous tissue, maximizing endplate coverage and promoting sagittal balance, are provided. Insertion and fixation can be accomplished through a narrow access window, thereby allowing better access to more spinal levels while being less invasive than other approaches. The spinal implants may facilitate fusion, and include visualization features to assist in the implantation and verify proper placement and vary segmental angle of lordosis. Methods of implanting the spinal implants to treat a patient's spine are also disclosed.Type: GrantFiled: April 17, 2020Date of Patent: December 6, 2022Assignee: CENTINEL SPINE, LLCInventors: Stephanie M. Bost, Andrew J. McQuaide, John Parry

Patent number: 10492836Abstract: An anterior cervical plate system is provided. The plate is configured to receive bone screws for attachment to and immobilization of adjacent vertebrae of the spine. The system includes a lock configured to prevent the bone screws from backing out of the plate. The lock includes at least one blocking surface that is movable between a blocked configuration preventing the bone screw from backing out and an unblocked configuration allowing passage of the bone screw. The lock achieves a blocked position in a rotation of less than 90 degrees while maintaining or increasing a low-profile.Type: GrantFiled: July 9, 2018Date of Patent: December 3, 2019Assignee: Centinel Spine, LLCInventors: Moti Altarac, Joey Reglos

Patent number: 10413426Abstract: The embodiments provide a spinal implant that is configured for midline insertion into a patient's intervertebral disc space. The spinal implant may include structural guidance features to facilitate the angular approach of fixation elements into the apertures. The spinal implant may also be a configured with a tactile or visual feedback response feature to allow the user to know when the fixation elements are fully seated within the apertures.Type: GrantFiled: February 9, 2017Date of Patent: September 17, 2019Assignee: CENTINEL SPINE, LLCInventors: John Parry, John J. Viscogliosi

Patent number: 10206786Abstract: The embodiments provide a spinal implant that is configured for lateral insertion into a patient's intervertebral disc space. The spinal implant may have a body having a tapered anterior portion and one or more apertures. The tapered anterior portion allows for concomitant distraction of soft tissue during insertion of the implant. In addition, at least some of the apertures are designed to permit a predetermined amount of nutation by a fixation element. The fixations elements that allow nutation enable the fixation element to toggle from one position to another, for example, during subsidence of the implant in situ.Type: GrantFiled: September 30, 2015Date of Patent: February 19, 2019Assignee: Centinel Spine, LLCInventors: John S. Thalgott, David T. Stinson, John J. Viscogliosi

Patent number: 10182831Abstract: Instruments and methods for preparing an intervertebral space for receiving an implant. An adjustable trial implant has an adjustable stop mechanism having a stop member connected thereto to vary the distance that a body portion of the trial implant can move into the intervertebral space. Cutting tools for forming cutouts in the adjacent vertebrae use the trial implant and/or a guide to position a cutting tool which may be a burr or a chisel. The chisel cutting tool can be moveable relative to a selected trial implant or the chisel cutting tools can be fixed onto a trial implant shaped body portion.Type: GrantFiled: January 10, 2014Date of Patent: January 22, 2019Assignee: CENTINEL SPINE LLCInventors: Thierry Marnay, Rudolf Bertagnoli, Francis P. Magee, Stephan Eckhof, David L. Nichols, Christophe Geisert

Patent number: 10085845Abstract: An intervertebral implant includes opposing upper and lower endplates that are configured to engage respective vertebral surfaces in an intervertebral space. The implant carries a plurality of bone fixation spikes that extend out from each endplate. The spikes define a plurality of outer surfaces that extend from a base to a tip. The spikes are laterally staggered, and have a height that increases along a longitudinal direction from the front toward the rear of the implant, and a define recess formed in at least one outer surfaces.Type: GrantFiled: April 14, 2016Date of Patent: October 2, 2018Assignee: Centinel Spine LLCInventors: Roger Berger, Joern Richter

Patent number: 9918850Abstract: The embodiments provide a spinal implant that is configured for midline insertion into a patient's intervertebral disc space. The spinal implant may have a body and the body comprises one or more apertures. The apertures receive fixation elements, such as a screw and the like. The fixation element may comprise one or more anti-backout features, such as a split ring. In addition, at least some of the apertures are designed to permit a predetermined amount of nutation by a fixation element. The apertures that allow nutation enable the fixation element to toggle from one position to another, for example, during subsidence of the implant in situ. Some of the apertures may be configured to rigidly lock with the fixation elements. Moreover, the spinal implant may include features, such as one or more bores, that can accommodate imaging marks to help guide a surgeon.Type: GrantFiled: October 27, 2014Date of Patent: March 20, 2018Assignee: CENTINEL SPINE, LLCInventors: John S.
