Patent number: 9956086Abstract: An intervertebral implant, alone and in combination with an insertion tool for inserting same and a method for inserting same. The implant has upper and lower parts which have universal movement relative to each other. Each of the upper and lower parts also has a surface engaging an adjacent vertebrae. Each part has a keel extending from said surface into a cutout in the adjacent vertebrae, and each keel has an anterior opening recess therein. An insert tool has a pair of arms which are received in the recess of the keels through the anterior opening to securely hold and insert the implant. Projections and matching indentations in each arm and the base of its recess securely attached each arm within its keel.Type: GrantFiled: February 15, 2017Date of Patent: May 1, 2018Assignee: CENTINEL SPINE LLCInventors: Thierry Marnay, Rudolf Bertagnoli, Francis P.

Patent number: 9872777Abstract: A modular, customizable system that provides components for assembling an implantable device is provided. The system allows the user to assemble an implantable spine stabilization device that is flexible and allows dynamic stabilization. The same system also provides components for assembling a rigid or non-flexible fusion-enabling spine stabilization device. The components of the system are easily interchangeable, allowing the user the ability to customize the assembled device for a true fit with the patient, as well as allow an easy conversion of the dynamic device into a fusion-enabling device. Associated insertion instruments and methods of use are also disclosed.Type: GrantFiled: March 17, 2014Date of Patent: January 23, 2018Assignee: PARADIGM SPINE, LLCInventors: Detlev Ganter, Stephan Eckhof, Guntmar Eisen, Sven Oliver Muckenfuβ, Markus Salversomer, Michael H.

Patent number: 9216024Abstract: The invention relates to the preparation of an intervertebral space with a trial implant (9), the insertion of an implant (5, 6, 7), the inserters (13, 16), and the method for feeding and inserting the implant (5, 6, 7) by means of an oblique anterior approach. In the novel improved method, the associated instruments (13, 16) for inserting an implant (5, 6, 7) into an intervertebral space, in particular for the lumbar spine at an oblique anterior angle of 45° was developed, the left side of the body being preferred for insertion of the implant (5, 6, 7). Either the implant (5, 6, 7) can be inserted all in one, or first the upper part (5) and lower parts (7) and then the inlay (6) may be inserted. By insertion by means of the left oblique anterior approach at 45°, optimum utilization of the area of the intervertebral space is ensured (footprint), and better retention of the implant is guaranteed by the exact chiselling at an angle of 90° normal to the respective intervertebral surface.Type: GrantFiled: September 16, 2005Date of Patent: December 22, 2015Assignee: DePuy Synthes Products, Inc.Inventors: Christophe Geisert, Thierry Marnay, Rudolf Bertagnoli, Eduard Kufeld, Barbara Schweizer, Stephan Eckhof

Publication number: 20150039038Abstract: An orthopedic screw fastener system which includes at least two screws and at least one bone plate. At least one screw is a locking screw comprising a screw head and a screw shank, the screw head being provided with a thread. At least one other screw is a non-locking screw comprising a non-threaded (i.e., smooth) screw head and a screw shank. The at least one bone plate has a thickness and it has at least two through-bores which are able to receive screws. The plate has two or more through-openings, each formed by at least two through-bores, each through-bore being defined by a midpoint and by a radius, and the through-bores are offset relative to each other and intersect each other in such a way that intersection lines and/or intersection surfaces extend into the depth of the through-opening.Type: ApplicationFiled: August 5, 2013Publication date: February 5, 2015Inventors: Stephan Eckhof, Josef Zrinski, Zoran Reiter, Frank Altermann, Rolf Maier, Davor Zrinski, Oliver Burckhardt
