Patent number: 9636234Abstract: A hybrid spinal implant device, and method of making the same are disclosed. The spinal implant device comprises two facing endplates, each having at least one anchoring wall or pin element, and a plastic spacer anchored to and located between the two endplates. The endplates may be manufactured from titanium. The plastic spacer may be manufactured from a radiolucent, and bio-compatible polymer-based material including polyetheretherketone (“PEEK”), polyetherketone, polyetherketoneketone, and/or fiber reinforced plastic. The endplates made of titanium allow for enhanced bone growth, while the plastic/PEEK spacer element allows for improved load absorption and distribution. The spinal implant device, using titanium endplates and a PEEK spacer, provides excellent radiolucency thereby eliminating the need for X-ray markers either intra- or post-operation. The manufacturing method for the hybrid spinal implant device uses injection molding to insert or back injection mold the spacer between the two endplates.Type: GrantFiled: December 9, 2015Date of Patent: May 2, 2017Assignee: DePuy Synthes Products, Inc.Inventors: Andreas Gfeller, Dirk Dittmann, Salman Chegini, Phillippe Lindenmann

Patent number: 9549822Abstract: The present disclosure relates to a spinal implant or spacer that addresses the variation in anatomy of vertebrae along the spine by having inferior and superior surface angle and convexity variations that are adapted to address the differences in lordosis and endplate surface convexity of the spine. The difference between the convexity of the superior and inferior surface of the spacer increases as the lordotic angle of the spacer increases. The spacers described herein thus provide overall improved fit into vertebral disc space and in some embodiments are even used in the absence of fusion for a prolonged period. The vertebral spacers described herein in some embodiments are used with supplemental internal fixation systems, such as an anchor plate. The interior of the spacer has channels and undercuts to increase graft volume and retention, support bony ingrowth, and bony stability for better secondary and tertiary stabilization.Type: GrantFiled: May 3, 2013Date of Patent: January 24, 2017Assignee: DePuy Synthes Products, Inc.Inventors: David Wimberley, Christopher Cain, Andreas Gfeller, Jared Schoenly, Frank Yohe, David Evans, Dirk Dittmann, Jayr Bass

Patent number: 9155578Abstract: Implementations of the present disclosure provide a fastener including a tip portion, a proximal portion, an advancement mechanism and an expandable member. The tip portion has a first surface. The proximal portion is configured for coupling to the tip portion and has a second surface. The mechanism advances the first surface toward the second surface. The expandable member includes a first end abutting the first surface of the tip portion and a second end abutting the second surface of the proximal portion. Advancement of the two surfaces toward each other advances the first end of the expandable member toward the second end of the expandable member. The expandable member is configured to expand in response to the advancement. At least one of the ends of the expandable member is a free end extending under and configured to rotate with respect to an abutting one of the first or second surfaces.Type: GrantFiled: February 28, 2012Date of Patent: October 13, 2015Assignee: DePuy Synthes Products, Inc.Inventors: Salman Chegini, Andreas Gfeller, Jacques Teisen
