Publication number: 20220409391Abstract: The disclosure provides an implant including first and second interconnected elongated articulating portions with vertebral contacting outer surfaces. The first and second interconnected elongated articulating portions have a first configuration for insertion into a disc space and a second configuration upon deployment in the disc space. In a first configuration the axes of the first and second interconnected elongated articulating portions are substantially axially aligned with each other and in a second configuration the axes of the portions are axially unaligned with each other. The first and second interconnected elongated articulating portions are configured to be deployed in situ from the first configuration to the second configuration by both pivoting. The implant is expandable in the height direction between the vertebral contacting outer surfaces while the implant is inside the disc space by sliding a portion of at least one of the first and second elongated articulating portions.Type: ApplicationFiled: July 1, 2022Publication date: December 29, 2022Inventors: Malan de Villiers, Neville Jansen

Publication number: 20220273445Abstract: The disclosure provides an intervertebral disc and related methods. An upper plate includes an upper vertebra contacting portion and a lower bearing surface portion. The upper vertebra contacting portion includes a convex central portion, and a fin or anchoring element with a transverse hole therethrough. A lower plate has a lower vertebra contacting surface and an upper bearing surface. The lower vertebra contacting surface of the lower plate has a convex central portion. The upper bearing surface has a concavity disposed opposite the convex central portion and wherein the convex central portion and the concavity have nesting curvatures. A core positioned between the upper and lower plates has rigid upper and lower convex surfaces configured to slide and translate over the bearing surfaces of the upper and lower plates.Type: ApplicationFiled: May 19, 2022Publication date: September 1, 2022Inventors: Malan de Villiers, Neville Jansen, Yves Arramon

Patent number: 11413156Abstract: A prosthetic intervertebral disc is formed of first and second end plates sized and shaped to fit within an intervertebral space and to be implanted from the back of the patient, thereby decreasing the invasiveness of the procedure. The posterior approach provides for a smaller posterior surgical incision and avoids important blood vessels located anterior to the spine particularly for lumbar disc replacements. The first and second plates are each formed of first, second and third parts are arranged in a first configuration in which the parts are axially aligned to form a low profile device appropriate for insertion through the small opening available in the TLIF or PLIF approaches described above. The three parts of both of the plates rotate and translate with respect to one another in situ to a second configuration or a deployed configuration in which the parts are axially unaligned with each other to provide a maximum coverage of the vertebral end plates for a minimum of insertion profile.Type: GrantFiled: March 19, 2020Date of Patent: August 16, 2022Assignee: Simplify Medical Pty Ltd.Inventors: Malan De Villiers, Neville Jansen

Patent number: 11357633Abstract: 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: GrantFiled: December 10, 2019Date of Patent: June 14, 2022Assignee: Simplify Medical Pty LtdInventors: Malan de Villiers, Neville Jansen, Yves Arramon

Publication number: 20220079771Abstract: Various implementations include intervertebral discs and associated methods of use and imaging. One implementation includes an intervertebral disc capable of imaging under MRI, the disc including: an upper plate including a polyaryletherketone (PAEK) portion having a lower bearing surface and an upper vertebra contacting surface, the upper surface formed at least in part from a metal for improved bone attachment; a lower plate including a PAEK portion having an upper bearing surface and a lower vertebra contacting surface, the lower surface formed at least in part from a metal for improved bone attachment; and a ceramic core to mate and articulate with respect to the bearing surfaces of the upper and lower plates, wherein upon imaging under X-ray the PAEK portion of the upper and lower plates are substantially completely invisible and the upper and lower vertebral contacting surfaces of the upper and lower plates are substantially completely visible.Type: ApplicationFiled: November 30, 2021Publication date: March 17, 2022Inventors: Yves Arramon, Malan de Villiers, Neville Jansen

Patent number: 11207190Abstract: An intervertebral prosthesis for insertion between adjacent vertebrae, in one embodiment, includes upper and lower prosthesis plates and a movable core. The prosthesis plates and optionally the core are formed of polyaryletherketone (PAEK) for improved imaging properties. A metallic insert is provided on each of the PAEK prosthesis plates providing a bone ongrowth surface.Type: GrantFiled: October 27, 2017Date of Patent: December 28, 2021Assignee: Simplify Medical Pty LtdInventors: Yves Arramon, Malan de Villiers, Neville Jansen
