Publication number: 20150142119Abstract: The present invention teaches an improved spinal fusion implant and method of implanting same. The implant includes a shell and an insert, the insert capable of situating first and second plates of the shell with respect to each other and of preventing unwanted loosening of fasteners placed through the shell and into the adjacent vertebral bodies. The method includes implanting a shell, selecting an insert from a plurality of inserts, and placing an insert between first and second plates of the shell.Type: ApplicationFiled: January 29, 2015Publication date: May 21, 2015Inventors: Thomas J.

Patent number: 8992537Abstract: A woven retention device for interfacing with a bone surface includes interwoven filaments forming a tubular lattice with protuberances distributed on interior and exterior surfaces of the lattice at a predetermined spatial relationship. The protuberances are formed by intersecting interwoven filaments. The retention device receives and surrounds a fastener. In a first, relaxed state, the retention device has multiple combinations of filament cross-section geometries at the intersection points, and the multiple combinations of filament cross-section geometries form multiple protuberance thicknesses. In a second state when surrounding at least a portion of the fastener, the retention device distributes pressure from the fastener to multiple points of contact on the exterior surface of the retention device such that a spatial relationship of the protuberances changes as a function of bone density of the bone surface and as a function of an interfacing surface shape of the fastener.Type: GrantFiled: September 16, 2014Date of Patent: March 31, 2015Assignee: Woven Orthopedic Technologies, LLCInventor: Christopher McDonnell

Publication number: 20130304124Abstract: A spinal plating system for vertebral fixation includes a plate, a compression screw, multiple fixation members and polyaxially adjustable locking rings. The plate is shaped to conform to the curvature of the spine and the surfaces of the vertebral bodies. The compression screw fits through an insert, and together they are guided by the plate as the screw is driven into one of the vertebrae, producing compression between the adjacent vertebrae. A retaining lip on the plate prevents backout of the compression screw. The polyaxial locking rings can be polyaxially pivoted to attain a desired orientation, and are lockable to the plate to maintain the orientation. The fixation members fit through openings in the polyaxial locking rings and the plate to fix the plate to the vertebrae. Locking the polyaxial locking rings fixes the position of the fixation members relative to the plate, and prevents backout of the fixation members.Type: ApplicationFiled: July 19, 2013Publication date: November 14, 2013Applicant: STRYKER SPINEInventors: Michael A. Dube, Frederick Marciano, Randall Porter, Nicholas Theodore, Eeric Truumees, Christopher McDonnell, Daniel F. Justin, Chad W. Lewis
