Publication number: 20240032970Abstract: The present invention is directed an anchor assembly for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The anchor assembly preferably includes a bone anchor, a body with a rod-receiving channel, an insert member (preferably a bushing), and a locking cap with a saddle. The anchor assembly preferably enables in-situ assembly where the bone anchor may be secured to the patient's vertebra prior to being received within the body of the bone anchor assembly. Accordingly, the anchor assembly enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body may be snapped onto the bone anchor and a spinal rod may be inserted into the rod-receiving channel.Type: ApplicationFiled: October 10, 2023Publication date: February 1, 2024Inventors: Fridolin J. Schlaepfer, Christian Ammann, Stefan Saladin

Patent number: 10729476Abstract: 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: GrantFiled: March 26, 2018Date of Patent: August 4, 2020Assignee: DePuy Synthes Products, Inc.Inventors: Daniel Thommen, Markus Weber, Jacques Teisen, Markus Kraft, Florian Kaufmann, Markus Hunziker, Felix Aschmann, Stefan Saladin, Martin Oswald, Roman Randegger

Patent number: 10022228Abstract: An implant system includes a fixation device that, in turn can include an expandable implant alone or in combination with an auxiliary implant. The expandable implant includes an expandable implant body that is made from an expandable material. The expandable material includes a polymer matrix and an expandable gas source contained within at least a portion of the polymer matrix. The implant system can further include an energy source configured to heat the polymer matrix to a temperature above its glass transition temperature, thereby causing the gas source to expand inside the polymer matrix. The fixation device can further include an insertion instrument configured to implant the fixation device into an anatomical cavity.Type: GrantFiled: June 29, 2016Date of Patent: July 17, 2018Assignee: DePuy Synthes Products, Inc.Inventors: Adrian Baumgartner, Robert Frigg, Cyril Voisard, Reto Nardini, Dieter Schmidli, Christian Brunner, Stefan Saladin
