Patent number: 10751187Abstract: An intersomatic cage, an intervertebral prosthesis, an anchoring device and an instrument for implantation of the cage or the prosthesis and the anchoring device are provided. An intersomatic cage or an intervertebral prosthesis fit closely to the anchoring device, which includes a body of elongated shape on a longitudinal axis, of curved shape describing, along the longitudinal axis, an arc whose dimensions and radius of curvature are designed in such a manner that the anchoring device may be implanted in the vertebral plate of a vertebra by presenting its longitudinal axis substantially along the plane of the intervertebral space, where the anchoring device is inserted, by means of the instrument, through a slot located in at least one peripheral wall of the cage or on at least one plate of the intervertebral disc prosthesis to penetrate into at least one vertebral plate.Type: GrantFiled: October 24, 2017Date of Patent: August 25, 2020Assignee: LDR MedicalInventors: Jerome Allain, Jean Lombard, Jeff Phelps, Pierce Nunley, Charles Gordon, Vincent Leone, Michael Hisey

Patent number: 9987044Abstract: Various methods, devices, and systems are disclosed that facilitate easier and more compact implantation of osteosynthesis devices. In some embodiments, implants are screwed into two vertebrae and a plate is used to hold and displace the spine. In some plate embodiments, at least one longitudinally elongated opening is disposed at one end of the plate and partially opening onto an edge of the plate. In some plate embodiments, at least one longitudinally elongated opening is disposed at one end of the plate having a portion sufficiently large to be inserted without disassembly in the fixation means of an implant already screwed into the spine when the fixation means are already assembled.Type: GrantFiled: January 24, 2017Date of Patent: June 5, 2018Assignee: LDR MedicalInventors: Joël Delecrin, Jérôme Allain, Patrick Tropiano, Serge Ganglof, Rémi Poncer

Publication number: 20180098859Abstract: An intervertebral disc prosthesis designed to be substituted for fibrocartilaginous discs ensures a connection between the vertebra of the vertebra column or the end of the latter. The prosthesis includes a pair of plates spaced from each other by a nucleus. The prosthesis has increased stability by providing the nucleus with a translation or rotation stop, or by inducing an angular correction between its plates contacting vertebra, or a combination of these characteristics. The stop includes parts external to the nucleus and contact surfaces perpendicular to their contact directions. Surgical methods and instrumentation for implanting the prosthesis are also described.Type: ApplicationFiled: October 16, 2017Publication date: April 12, 2018Inventors: Jacques Beaurain, Joel Delecrin, Michel Onimus, Herve Chataignier, Jerome Allain, Jean-Paul Frederic Steib

Patent number: 8221457Abstract: The present invention relates to an osteosynthesis device, particularly for spinal support or correction, enabling easier and compact implantation, that can be particularly used in the case of implantation via the anterior approach, and a preassembly method for such a device. Said device comprises implants screwed into two vertebrae and one plate characterized in that the plate is joined to at least one implant by attachment structure able to hold said plate without preventing the implant from rotating on its screwing axis, or without preventing a specified clearance of the plate with respect to the implant. In this way, said attachment structure make it possible to continue screwing the implant, or adjust the position of the plate after the plate has been on the implant.Type: GrantFiled: October 18, 2002Date of Patent: July 17, 2012Assignee: LDR MedicalInventors: Joël Delecrin, Jérôme Allain, Patrick Tropiano, Serge Ganglof, Rémi Poncer

Patent number: 8162988Abstract: An osteosynthesis device is proposed, particularly for spinal support or correction, enabling easier and compact implantation, that can be particularly used in the case of implantation via the anterior approach, and a preassembly method for such a device. In various embodiments, the device comprises implants screwed into two vertebrae (0) and a plate (2) used to hold and displace the spine. In various embodiments, the plate (2) comprises on at least one of its ends at least one longitudinally elongated opening, the opening having firstly at least one part opening onto an edge of the plate, or one part of a sufficiently large size (s210b) to be able to be inserted without disassembly in the fixation means of an implant (1) already screwed into the spine when the fixation means are already assembled.Type: GrantFiled: October 18, 2002Date of Patent: April 24, 2012Assignee: LDR MedicalInventors: Joël Delecrin, Jérôme Allain, Patrick Tropiano, Serge Ganglof, Rémi Poncer
