Publication number: 20130131677Abstract: The present invention provides a clamp assembly which allows the surgeon to snap a bone fixation assembly onto a bone fixation rod at an intermediate location along the length of the rod. It is not necessary to “thread” the clamp onto the rod starting at the end and sliding it down the length of the rod to the desired location. In particular, this invention provides a novel clamp assembly for use with standard bone fixation rods, and bone pins. The clamp allows the interconnection of a bone fixation rod with a bone pin locking assembly including a bone pin vise. The clamp is a single-piece construction, having a jaw capable of loosely capturing the bone fixation rod when the surgeon presses the jaw onto the rod. The assembly may be rigidly fixed to the rod using a bolt which tightens the jaw onto the rod.Type: ApplicationFiled: January 10, 2013Publication date: May 23, 2013Applicant: SYNTHES USA, LLCInventor: SYNTHES USA, LLC

Patent number: 8420740Abstract: The present invention is directed to a bioadhesive thermogelling hydrogel composition for repairing and/or augmenting an intervertebral disc. The bioadhesive thermogelling hydrogel composition can be cross linked with the surrounding tissue so as to potentially serve as a nucleus pulposus replacement or augmentation along with serving to repair annular tears or fissure. The bioadhesive thermogelling hydrogel composition may include three main components: a thermal responsive polymer, an amine-containing polymer and a crosslinking component. All three components can be modified and combined in numerous ways to serve the need of the system as long as the amine-containing component is kept separate from the crosslinking component until the components are injected. The incorporation of a two-part crosslinking thermal responsive hydrogel permits smaller amounts of the crosslinking component to be used and enables the crosslinking dialdehyde to be delivered locally into the tissue that will react with the hydrogel.Type: GrantFiled: August 21, 2007Date of Patent: April 16, 2013Assignees: Synthes USA, LLC, Drexel UniversityInventors: Nigel Gordon Smith, Meredith Hans, Anthony M. Lowman, Andrea Jennifer Vernengo, Garland Fussell
