Patent number: 10925749Abstract: The present disclosure provides an intervertebral cage including superior and inferior members each including an engagement surface for engaging a corresponding vertebrae. The intervertebral cage also includes a posterior member that extends between a posterior end of the superior and inferior members and spaces them from each other in a superior-inferior direction. The superior and inferior members extend in a posterior-to-anterior direction from the posterior member and define anterior free ends to form a substantially open anterior end between the superior member and the inferior member in a posterior-anterior direction. The engagement surfaces of the superior and inferior members substantially diverge from each other in the superior-inferior direction along the posterior-to-anterior direction. The superior and inferior members each include first apertures extending therethrough in the superior-inferior direction that define a pathway through the intervertebral cage in the superior-inferior direction.Type: GrantFiled: August 23, 2018Date of Patent: February 23, 2021Assignee: REVIVO MEDICAL, LLCInventors: Eric H. Ledet, Glenn Patrick Sanders

Patent number: 10925751Abstract: A vertically expandable intervertebral cage, deployment devices, and methods for using the same. The intervertebral cage can include a circuitous body at least partially enclosing an interior volume. The intervertebral cage can also include a front panel which can be formed into a wedge for facilitating implantation of the intervertebral cage into an intervertebral space. The intervertebral cage can be converted from an undeployed configuration, wherein the height of the intervertebral cage is reduced, to a deployed configuration, wherein the height of the intervertebral cage is increased to support end plates of the vertebrae. The intervertebral cage can be converted from the undeployed configuration to a deployed configuration by using a deployment device such as an implantation device and a guide wire. The deployment device can be used to impart a force upon the cage.Type: GrantFiled: June 29, 2018Date of Patent: February 23, 2021Assignee: EIT Emerging Implant Technologies GmbHInventor: Morgan Packard Lorio

Patent number: 10898342Abstract: A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. An access cannula may be introduced over the first dilator tube. A drill may be inserted through the access cannula and used to perform a foraminoplasty. Surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.Type: GrantFiled: September 10, 2018Date of Patent: January 26, 2021Assignee: DePuy Synthes Products, Inc.Inventor: Rudolf Morgenstern Lopez

Patent number: 10898346Abstract: An expandable intervertebral fusion implant capable of being expanded in three dimensions, said implant including an inferior component, including a plate, and a first wedge slidably connected to the plate, the first wedge having a first surface, and a superior component including a second wedge, the second wedge having a second surface, wherein the first surface is operatively arranged to engage the second surface to displace the superior component relative to the inferior component. The surfaces of the wedges may be angled and include a plurality of corrugations or steps which engage to allow the implant to expand and collapse.Type: GrantFiled: July 19, 2019Date of Patent: January 26, 2021Inventor: Loubert S. Suddaby

Patent number: 10893953Abstract: A spinal implant is provided including an upper surface, a lower surface, a front surface and a back surface, two side surfaces extending between the upper surface and the lower surface, the two side surfaces extending between the front surface and the back surface and an opening positioned closer to the back surface than the front surface. The opening is provided to contain graft material that spans between a cortical rim of the upper vertebral body and the cortical rim of the lower vertebral body. The method includes packing the opening with graft material, wherein the graft material spans between the decorticated cortical rim of the upper vertebral body and the decorticated cortical rim of the lower vertebral body.Type: GrantFiled: December 13, 2018Date of Patent: January 19, 2021Inventor: Seth Neubardt

Patent number: 10893951Abstract: Devices and related methods for the dynamic correction of spinal deformities are disclosed. The devices and methods are particularly useful for correcting an abnormal curvature of the spine. In one exemplary embodiment, a method for correcting deformity via a spinal implant that can include a polymer between or attached to a top and bottom plate, which can exist in a wedge-shaped configuration in order to apply asymmetric forces to the spinal column, is provided. The implant may be inserted between adjacent vertebrae comprising part of the abnormal curvature, thereby restoring the normal curvature of a spine.Type: GrantFiled: August 7, 2019Date of Patent: January 19, 2021Assignee: Minimally Invasive Spinal Technology, LLCInventors: Alexander Singh, Rohit Rustagi, George Vithoulkas, Eric Taleghani, Hasan Syed
