Publication number: 20240091022Abstract: A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.Type: ApplicationFiled: November 27, 2023Publication date: March 21, 2024Inventors: Collin Newman, Christian Karl Schultz, Steven Willis, Amir Ali Sharifi-Mehr, Oliver Buchert, Christopher P. Bell, Andrew Edward Ehlers, Anna Reza, Marc Gilles Long, Joseph Henry Robinson

Publication number: 20230404599Abstract: A method of inserting a fastener includes positioning a portion of a stylet within a cannulated shaft of the fastener, advancing a tip of the stylet through a first bone and into a second bone, advancing a leading end of the fastener along the stylet through the first bone and into the second bone, and removing the stylet from the cannulated shaft of the fastener and the bone. In another embodiment, a method of inserting a fastener includes positioning a portion of a stylet within a cannulated shaft of the fastener, advancing a tip of the stylet into a bone to a first depth without advancing the fastener into the bone, advancing a leading end of the fastener along the stylet into the bone to a second depth without further advancing the stylet into the bone, and removing the stylet from the cannulated shaft of the fastener and the bone.Type: ApplicationFiled: June 5, 2023Publication date: December 21, 2023Inventors: Amir Ali Sharifi-Mehr, Oliver Buchert, Shawn D. Stad, Paul R. Rochette, Nicole Renee Fallacaro, Lori Dombrowski, Mitch Baldwin, Christopher P. Bell

Publication number: 20230380983Abstract: A spinal interbody implant includes an outer shell, a fill material disposed within the outer shell and a plurality of tubes extending from a first outer surface of the implant to a second outer surface of the implant through the fill material. The fill material is more porous than the outer shell and the plurality of tubes.Type: ApplicationFiled: October 13, 2021Publication date: November 30, 2023Inventors: Sean Corcoran, Keith Fava, Kenneth Dieselman, Jennifer Anne Moore, Amir Ali Sharifi-Mehr, Christopher P.

Patent number: 11712348Abstract: An expandable, intervertebral spacer includes a top component and a base component in engagement with the top component, the base component defining at least one channel for receiving a hardening material, and placement of the hardening material within the channel causes the top component to move between a first position in which the top component is a first distance from the base component and a second position in which the top component is a second distance from the base component, the second distance being greater than the first distance. The hardening material can be removed from the channel by a flexible coring tool, and the top component forced toward the base component to collapse the spacer.Type: GrantFiled: July 29, 2020Date of Patent: August 1, 2023Assignee: Stryker European Operations Holdings LLCInventors: Christopher P. Bell, Agustin Quintana

Patent number: 11707284Abstract: A stylet control system for selectively advancing and retracting a stylet includes a stylet having a first end and a second end, the second end being threaded, a screwdriver defining a bore for receiving a portion of the stylet and having a screw-engaging end for engaging a screw, the stylet being rotationally fixed relative to the screwdriver. The system includes a control device having a passage for receiving the screwdriver and having an inner portion defining a lumen for receiving the portion of the stylet, the inner portion being threaded for engaging the threaded second end of the stylet, when the screwdriver is rotated in the first rotation direction and the control device is prevented from rotating, the screwdriver advances the screw in the first axial direction and the stylet retracts in a second axial direction, opposite the first axial direction.Type: GrantFiled: March 6, 2020Date of Patent: July 25, 2023Assignee: K2M, Inc.Inventors: Amir Ali Sharifi-Mehr, Oliver Buchert, Shawn D. Stad, Paul R. Rochette, Nicole Renee Fallacaro, Lori Dombrowski, Mitch Baldwin, Christopher P. Bell
