Patent number: 8568457Abstract: A growing rod for mounting between attachment mechanisms that are secured to anatomical structures of a patient having scoliosis. The growing rod includes a base rod having an attachment end, an extendable rod that is translatable relative to the base rod along a longitudinal axis and a housing enclosing at least a portion of the extendable rod therein. A magnet is rotatably mounted within the housing and is enclosed by a top magnet cover and a bottom magnet cover. The magnet includes a first pole and a second pole. A gear reduction mechanism is associated with the magnet and the extendable rod. The gear reduction mechanism reduces an output rotation to the extendable rod relative to an input rotation from the magnet.Type: GrantFiled: December 1, 2010Date of Patent: October 29, 2013Assignee: DePuy Synthes Products, LLCInventor: Markus Hunziker

Patent number: 8540774Abstract: The present invention is directed to a low profile intervertebral implant (10) for implantation in an intervertebral disc space (D) in-between adjacent vertebral bodies (V). The intervertebral implant includes a plate (40) preferably coupled to a spacer (20). 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 (hs) of the spacer and the plate may be implanted within the intervertebral disc space in conjunction with the spacer.Type: GrantFiled: November 5, 2008Date of Patent: September 24, 2013Assignee: DePuy Synthes Products, LLCInventors: Thomas Kueenzi, Ryan Walsh, Tom Pepe, Markus Hunziker, David Koch

Publication number: 20120245431Abstract: 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: September 20, 2011Publication date: September 27, 2012Inventors: Cyril Baudouin, Matthew Fenn, Markus Hunziker, Sean Saidha, Michael White, Khawar Siddique, Brian Perri, Philippe Lindenmann

Publication number: 20120130428Abstract: 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: ApplicationFiled: November 22, 2011Publication date: May 24, 2012Applicant: SYNTHES USA, LLCInventor: MARKUS HUNZIKER

Publication number: 20110190817Abstract: An interspinous process spacer for implantation in an interspinous space between a superior spinous process and an inferior spinous process includes a balloon-like body, a first deployable protrusion and a second deployable protrusion. The body has a distal end, a proximal end and a longitudinal axis extending between the proximal and distal ends. The spacer is arrangeable in an unexpanded configuration and an expanded configuration. The first deployable protrusion is mounted proximate the proximal end and the second deployable protrusion is mounted proximate the distal end. The first and second deployable protrusions are oriented generally parallel to the longitudinal axis in the unexpanded configuration and generally perpendicular to the longitudinal axis in the expanded configuration.Type: ApplicationFiled: November 5, 2010Publication date: August 4, 2011Applicant: SYNTHES USA, LLCInventors: Daniel THOMMEN, Markus WEBER, Jacques TEISEN, Markus KRAFT, Florian KAUFMANN, Markus HUNZIKER, Felix ASCHMANN, Stefan SALADIN, Martin OSWALD, Roman RANDEGGER

Publication number: 20100145459Abstract: 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: ApplicationFiled: November 6, 2009Publication date: June 10, 2010Inventors: 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
