Patent number: 10786363Abstract: Spacerless artificial disc replacements (ADR) are disclosed. One preferred embodiment includes two saddle-shaped components to facilitate more normal spinal flexion, extension, and lateral bending while limit axial rotation, thereby protecting the facet joints and the annulus fibrosus (AF). Either or both of the superior and inferior components are made of a hard material such as chrome cobalt, titanium, or a ceramic including alumina, zirconia, or calcium phosphate. The articulating surfaces of the ADR are also preferably highly polished to reduce friction between the components. Metals, alloys or other materials with shape-memory characteristics may also prove beneficial.Type: GrantFiled: March 18, 2019Date of Patent: September 29, 2020Assignee: SpineCore, Inc.Inventors: Bret A. Ferree, David Tompkins

Patent number: 10398572Abstract: A kit for preparing an intervertebral disc space for receiving an implant (100) includes a plurality of trials (152) having different sizes. Each trial (152) includes a body (154) insertible into an intervertebral disc space, the body (154) having a leading end (162), a trailing end (164), a top surface (156) and a bottom surface (160), the top surface of the body having a first groove (176) formed therein. Each implant also includes a flange (166) secured to the trailing end (164) of the body (154), the flange (166) having a first channel (180) aligned with the first groove (176), wherein each of the different sized trials has a different flange thickness. The flange thickness controls advancement of a cutting tool such as a chisel (192) into the first groove at the top surface of the trial body, which controls the depth of the cut into vertebral bone.Type: GrantFiled: May 11, 2015Date of Patent: September 3, 2019Assignee: SpineCore, Inc.Inventor: Rafail Zubok

Patent number: 10369005Abstract: A method for replacing at least a portion of an intervertebral disc in a spinal column includes: removing the portion of the intervertebral disc from the spinal column; and inserting an apparatus for replacing the portion of the intervertebral disc into an intervertebral disc space defined substantially between adjacent vertebral bones of the spinal column, and positioning the apparatus between the vertebral bones, wherein the apparatus is operable to permit the adjacent vertebral bones to articulate relative to one another about at least one of: (i) a first center of rotation for at least one of flexion and extension that is located outside the intervertebral disc space, and (ii) a second center of rotation for lateral bending that is located outside the intervertebral disc space.Type: GrantFiled: January 11, 2016Date of Patent: August 6, 2019Assignee: SpineCore, Inc.Inventors: Rafail Zubok, Antonio Valdevit, Michael W. Dudasik, Joseph P. Errico

Patent number: 10299933Abstract: This invention improves upon prior art total disc replacements (TDRs) by more closely replicating the kinematics of a natural disc. The preferred embodiments feature two or more fixed centers of rotation (CORs) and an optional variable COR (VCOR) as the artificial disk replacement (ADR) translates from a fixed posterior COR that lies posterior to the COR of the TDR to facilitate normal disc motion. The use of two or more CORs allows more flexion and more extension than permitted by the facet joints and the artificial facet (AF). AF joint-like components may also be incorporated into the design to restrict excessive translation, rotation, and/or lateral bending.Type: GrantFiled: December 13, 2017Date of Patent: May 28, 2019Assignee: SpineCore, Inc.Inventors: Bret A. Ferree, David Tompkins

Patent number: 10213322Abstract: A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.Type: GrantFiled: September 11, 2017Date of Patent: February 26, 2019Assignee: SpineCore, Inc.Inventors: Joseph P. Errico, Michael W. Dudasik, Thomas J. Errico, Rafail Zubok
