Patent number: 9943339Abstract: An osseous anchorage implant comprising an attachment structure adapted to receive and be attached to at least one bar is disclosed. The implant is made up of an osseous anchor and an attachment head bearing the attachment means. The attachment head is suitably traversed by a channel that is adapted to receive the bar. The attachment head comprises a clamp that is adapted to clamp the bar against an inside support wall of the channel. The implant is further characterized by the attachment means and the support wall enabling the rotation of the bar about a first axis that is not parallel to the longitudinal axis of the bar. The clamp comprises a moving clamping face, that is adapted to contact the bar, and that is borne by a support head. The bar is enabled to be introduced into the channel from a side of the channel.Type: GrantFiled: February 7, 2017Date of Patent: April 17, 2018Assignee: LDR MedicalInventors: Jacques Beaurain, Joel Delecrin, Herve Chataigner

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

Publication number: 20180070990Abstract: A spinal internal implantation device for osteosynthesis has one or more bars for supporting for moving the spine and at least one implant for connecting the bars and vertebrae. The implant includes a blown anchor attached to a body of the implant and a fixation arrangement for the bars. The fixation arrangement includes a clamp for clamping the bar against internal walls of a channel formed in the body of the implant. At least part of the length of the bars includes a transversal bearing structure that is a cross-section of the bars having at least one flat part of a part having a lower forepost convexity than the rest of the cross section.Type: ApplicationFiled: September 19, 2017Publication date: March 15, 2018Inventors: Jacques Beaurain, Joel Delecrin, Michel Onimus, Isabelle Koenig, Alain Ducolombier, Marc Pierunek, Herve Chataigner, Marielle Derosi, Agnes DePostel
