Publication number: 20220087832Abstract: Embodiments of the disclosure provide systems and methods of removing a core from an intervertebral prosthetic disc. The method may include: securing a multipart prosthetic disc to a distal end of a removal instrument by grasping at least a portion of the multipart prosthetic disc between a pair of core removal arms on the placement instrument; inserting the pair of core removal arms between two prosthetic disc plates of the intervertebral prosthetic disc to distract the plates away from one another; and removing the core from the intervertebral prosthetic disc with the removal instrument. The removal instrument may include: an inner shaft connected to the pair of core removal arms; and an outer shaft movable with respect to the inner shaft and including an activation mechanism for causing the arms to grasp the core for removal.Type: ApplicationFiled: December 1, 2021Publication date: March 24, 2022Inventor: Yves Arramon

Publication number: 20220008224Abstract: Systems and methods for robotically distracting a disc space are provided for implantation of an intervertebral prosthetic disc. The system includes a 3D modeling system for creating a 3D model of first and second vertebra adjacent the disc space and identifying positions of the first and second vertebrae. A robotic distractor precisely opens the disc space just large enough to receive a selected intervertebral disc. A computing system stores and processes the 3D model and the positions of the first and second vertebrae before and after distraction.

Publication number: 20200138581Abstract: 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 10, 2019Publication date: May 7, 2020Applicant: Simplify Medical Pty LtdInventors: Malan de Villiers, Neville Jansen, Yves Arramon
