Patent number: 11944553Abstract: Disclosed herein are expanding spinal fusion cage embodiments including an expandable cage assembly configured to expand from a collapsed state to an expanded state in an intervertebral space when inflated with a material. The assembly can include an inflatable section defining an interior volume configured to receive the material and expand the interior volume in response to a pressure from the received material to cause the expandable cage assembly to transition from the collapsed state to the expanded state, and a stabilization section configured to restrain the inflatable section during inflation.Type: GrantFiled: January 8, 2021Date of Patent: April 2, 2024Assignees: DePuy Synthes Products, Inc., Stratasys, Inc.Inventors: Peyton Hopson, Hassan Serhan, Eric Buehlmann, Robert Sommerich, Thomas Gamache, Cynthia Star, Philip Reeves, Oliver Smith, David Hayden, Loic Le Merlus

Publication number: 20230373190Abstract: A method of creating a clad metal part is provided. The method includes explosion bonding a plate comprised of a base layer and an interlayer. The explosion bonded plate is then cut into bars which are roll bonded with a clad layer. Ultimately a part is fabricated from the roll bonded bar. The solution enables parts to have material combinations and resulting physical properties more optimal for an application than a single bonding process.Type: ApplicationFiled: July 10, 2023Publication date: November 23, 2023Inventors: PAUL KNIGHT, ERIC GAMACHE
