Patent number: 10512548Abstract: An intervertebral spacer implant (80) is provided with a retention mechanism (86) to help alleviate expulsion and movement of the implant when placed in the spine while providing an implant that is easier to insert in the spine. In one embodiment the retention mechanism comprises a keel on at least one of the inferior or superior faces of the spacer implant preferably extending in an anterior-posterior direction. In another embodiment the implant comprises a spacer (84) and a plate (82), the plate comprising a supplemental or alternative retention mechanism. In one embodiment the retention mechanism comprises one or more holes (88) in the anterior end of the plate. In yet another embodiment, the retention mechanism comprises one or more blades that are in a first position when inserted and are preferably rotated to a second position that engages the superior and inferior vertebrae.Type: GrantFiled: January 15, 2016Date of Patent: December 24, 2019Assignee: DePuy Synthes Products, Inc.Inventors: Dominique Messerli, Ryan T. Walsh, Brandon L. Randall, David E. Evans, Jacqueline Myer, David Koch, Markus Hunziker

Patent number: 10507042Abstract: A growing rod for mounting between attachment mechanisms that are secured to anatomical structures of a patient having scoliosis. The growing rod includes an outer housing and an inner housing disposed within the outer housing. The inner housing includes a magnet assembly including a magnet having a first pole and a second pole and a gear reduction mechanism coupled to the magnet. A first rod is secured to the inner housing and a second rod is secured to the outer housing. The gear reduction mechanism reduces an output rotation of the magnet to rotate a driver that operates to move the inner housing along a longitudinal axis with respect to the outer housing.Type: GrantFiled: January 8, 2018Date of Patent: December 17, 2019Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventor: Markus Hunziker

Patent number: 10433976Abstract: An implant for insertion into a disc space between vertebrae, wherein the implant includes a spacer portion, a plate portion coupled to the spacer portion, two bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively backing-out of the plate portion. The retention mechanism may be in the form of a spring biased snapper element that is biased into communication with the bone fixation elements so that once the bone fixation element advances past the snapper element, the snapper element is biased back to its initial position in which the snapper element interfaces with the bone fixation elements. Alternatively, the retention mechanism may be in the form of a propeller rotatable between a first position in which the bone fixation elements are insertable to a second position where the bone fixation elements are prevented from backing-out.Type: GrantFiled: July 22, 2016Date of Patent: October 8, 2019Assignee: DePuy Synthes Products, Inc.Inventors: William P. McDonough, William L. Strausbaugh, Christopher Bonner, Thomas Pepe, Ralph Meili, Markus Hunziker, Michael Jeger, Thomas Kueenzi, David Koch, Rainer Ponzer, Joern Richter, Roger Berger

Publication number: 20190223854Abstract: A retractor includes a first arm, a second arm, and a translating member. The first arm comprises a proximal portion configured to retain a first retractor member and a distal portion configured to rotate relative to the proximal portion about a first axis. The second arm is configured to retain a second retractor member, such that rotation of the distal portion about the first axis causes the first retractor member to pivot toward or away from the second retractor member when the first retractor member and the second retractor member are coupled to the first arm and the second arm, respectively. The translating member is coupled between the proximal portion and the distal portion, and is configured to receive a drive force that causes the translating member to bias the distal portion to pivot relative to the proximal portion about the first axis.Type: ApplicationFiled: April 2, 2019Publication date: July 25, 2019Inventors: Cyril Baudouin, Matthew Fenn, Markus Hunziker, Sean Saidha, Michael White, Khawar Siddique, Brian Perri, Philippe Lindenmann

Publication number: 20190151564Abstract: An injection device includes a product container having an injection needle, a needle protection cap detachably secured to the product container surrounds the injection needle and seals same in a sterile manner. A cap is connected to the needle protection cap, via a remover element having an engaging element, in such a way that the removal of the cap from the injection device brings about the removal of the needle protection cap from the product container, where the engaging element is in an engaging position in relation to the needle protection cap, where in the engaging position, a section of the needle protection cap is arranged distally in line with the engaging element, characterized in that the cap and the engaging element are coupled in such a way that the cap is or can be moved relative to the engaging element during the removal from the injection device.Type: ApplicationFiled: January 28, 2019Publication date: May 23, 2019Inventors: Christian Schrul, Markus Tschirren, Markus Hunziker

Patent number: 10137003Abstract: The present invention is directed to a low profile intervertebral implant for implantation in an intervertebral disc space in-between adjacent vertebral bodies. The intervertebral implant includes a plate preferably coupled to a spacer. The plate is preferably formed from a first material and the spacer is preferably formed from a second material, the first material being different from the second material. The plate is preferably sized and configured so that the plate does not extend beyond the perimeter of the spacer. In this manner, the plate preferably does not increase the height profile of the spacer and the plate may be implanted within the intervertebral disc space in conjunction with the spacer.Type: GrantFiled: July 21, 2017Date of Patent: November 27, 2018Assignee: DePuy Synthes Products, Inc.Inventors: Thomas Kueenzi, Ryan T.
