Patent number: 11678996Abstract: An angled fixation device, such as an angled screw. This angled fixation device may be used by the surgeon to secure a spacer to a spinal disc space. The proximal end portion of the angled fixation device is driven perpendicular to the anterior wall of the spacer, and so is parallel to the vertebral endplates and in-line with the inserter. The distal end portion of the angled fixation device is oriented at about a 45 degree angle (plus or minus 30 degrees) to the vertebral endplate it enters.Type: GrantFiled: December 18, 2019Date of Patent: June 20, 2023Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Thomas Gamache, Joseph Childs, Derek Shaw, Jonathan Howe, Michael Gorhan, Shawn Stad, Kevin Flaherty

Patent number: 11311318Abstract: Various exemplary methods and devices are provided for fixing bone anchors to bone. In general, the methods and devices can allow for a bone anchor to be fixed to a bone at a desired angle to a receiver member. In an exemplary embodiment, a bone anchor assembly is provided that includes a bone anchor configured to engage bone, a receiver member that seats a spherical head of the bone anchor and a spinal fixation element, a compression member seated within the receiver member, proximally of the head of the bone anchor, and a closure mechanism seated within the receiver member, proximally of the compression member. One or more of the receiver member, the compression member, and the closure mechanism can have gripping features thereon configured to secure the bone anchor and/or the spinal fixation element within the receiver member, thereby reducing a risk of slippage of the bone anchor and/or the spinal fixation element with respect to the receiver member.Type: GrantFiled: June 25, 2019Date of Patent: April 26, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Frank Spratt, Philip A.
