Publication number: 20190183654Abstract: An intervertebral prosthesis for insertion between adjacent vertebrae includes an upper plate, a lower plate and a core. The core is retained between the upper and lower plates by a retention feature in the form of central projections on the plates and a corresponding opening in the core. The retention feature is designed to allow the plates to slide over the upper and lower surfaces of the core in the anterior/posterior direction and in the lateral direction and to allow the plates to rotate with respect to each other and the core. The retention feature is also designed to prevent contact between the first and second plates during sliding movement of the plates over the core.Type: ApplicationFiled: December 14, 2017Publication date: June 20, 2019Applicant: Simplify Medical Pty LimitedInventors: Yves Arramon, David Hovda

Patent number: 10206785Abstract: A radiolucent intervertebral prosthesis is implanted in an environment that has been prepared in a manner which enhances radiopacity of the prosthesis and/or the environment. A liquid, powder, or other fluid radiopaque (RO) material, such as iohexol, is introduced into an implantation site, either by directly introducing the material into the site and/or by applying the material to a surface of the implant. The presence of the RO material in the implantation site provides contrast with the material of radiolucent prosthesis while the implantation site is being radiographically imaged, e.g. during fluoroscopic visualization while the prosthesis is being implanted. During implantation, the RO material helps the physician view and manipulate the implant, and after the implantation is complete, the RO material will be resorbed or otherwise lost from the implantation site so that the area returns to a radiolucent condition to facilitate subsequent radiographic imaging when needed.Type: GrantFiled: June 28, 2016Date of Patent: February 19, 2019Assignee: Simplify Medical Pty LtdInventors: Yves Arramon, David Hovda, Mark Alvis, Lisa Metelman

Patent number: 10085848Abstract: A dynamic intervertebral spacer includes a ring which is split on an anterior portion. A posterior portion of the ring acts as a torsion spring. After implantation, the ring is able to act as a spring between superior and inferior vertebral bodies, thus allowing dynamic bone growth in fusion procedures.Type: GrantFiled: July 15, 2016Date of Patent: October 2, 2018Assignee: Simplify Medical Pty LtdInventors: Yves Arramon, David Hovda

Publication number: 20180116803Abstract: An intervertebral disc is provided having an upper plate, a lower plate, and a core. The upper and lower plates include outer vertebral body contacting surfaces which are provided with attachment enhancing features to ensure bone integration. The attachment enhancing features shown include one or more fins, serrations and teeth. An opposite surface of the plates from the vertebral body contacting surfaces is formed with a recess which serves as a bearing surface for the core. In order to form an intervertebral disc with a lower disc height, at least one of the recesses is provided opposite a corresponding dome shaped portion on the vertebral body contacting surfaces. This allows the plates to be formed with a thinner profile for a smaller overall disc height. In addition to providing a lower overall height to the artificial disc, the dome shaped portion of the plates also provides a more anatomically shaped outer vertebral body contacting surface.Type: ApplicationFiled: December 14, 2017Publication date: May 3, 2018Applicant: Simplify Medical Pty LtdInventors: Malan de Villiers, Neville Jansen, Yves Arramon

Publication number: 20170231777Abstract: An artificial intervertebral disc with shock absorption includes upper and lower plates disposed about a shock absorbing movable core. The upper and lower plates have an outer surface which engages a vertebrae and an inner bearing surface. The shock absorbing core includes a unitary member of a rigid material having at least one lateral cut between upper and lower surfaces of the core to allow the upper and lower surfaces to move resiliently toward and away from each other. This allows the core to absorb forces applied to it by the vertebrae.Type: ApplicationFiled: October 3, 2016Publication date: August 17, 2017Inventor: Yves ARRAMON

Publication number: 20170071757Abstract: An intervertebral spacer is designed particularly for patients who are not candidates for total disc replacement. The spacer maintains disc height and prevents subsidence with a large vertebral body contacting surface area while substantially reducing recovery time by eliminating the need for bridging bone. The intervertebral spacer or fusion spacer includes a rigid spacer body sized and shaped to fit within an intervertebral space between two vertebral bodies. In one embodiment, the spacer body has two opposed metallic vertebral contacting surfaces, at least one fin extending from each of the vertebral contacting surfaces and configured to be positioned within slots cut into the two vertebral bodies. Holes, if present, cover less than 40 percent of the entire vertebral body contacting surfaces to provide increased bone ongrowth surfaces and to prevent subsidence.Type: ApplicationFiled: November 22, 2016Publication date: March 16, 2017Applicant: Simplify Medical Pty LtdInventors: David Hovda, Yves Arramon
