Patent number: 9445844Abstract: The present invention provides a Posterior Dynamic Stabilization (PDS) device that allows elongation, which is a critical requirement for a PDS device as it allows pedicles to travel naturally in flexion, extension, and lateral bending of the spine. This interpedicular travel preserves a more natural center of rotation unlike other PDS devices that simply allow bending. In particular, the invention involves a PDS spring rod, wherein the helix is created with composite flow molding (CFM) technology and comprises a polymer matrix reinforced with continuous carbon fibers, wherein the fibers are oriented substantially parallel to the centerline of the helix, thereby creating a high strength spring.Type: GrantFiled: March 24, 2010Date of Patent: September 20, 2016Assignee: DePuy Synthes Products, Inc.Inventors: Missoum Moumene, Jonathan Fanger, Kevin Flaherty

Patent number: 9320543Abstract: A posterior dynamic spinal stabilization device utilizing a spinal rod, a fixed anchor, a mobile anchor adapted for both translation and pivoting, a mobile anchor-limiting stop affixed to the rod and an optional bumper-type, a rod with at least one limiting stop. It allows predetermined and prescribed interpedicular motion. It allows the use of traditional pedicle screw-rod placement techniques in a flexible system possessing many treatment options using familiar components that are familiar to the surgeon, and can be used on multiple levels (especially to top off) and can transition loads by limiting displacements.Type: GrantFiled: October 27, 2009Date of Patent: April 26, 2016Assignee: DePuy Synthes Products, Inc.Inventors: Jonathan Fanger, Missoum Moumene

Patent number: 9320552Abstract: Methods and devices are provided for passively locking a bone screw within a bone plate. In particular, the methods and devices allow a bone screw to be locked within a thru-hole in a bone plate without requiring any additional locking steps. In an exemplary embodiment, an annular feature is provided in a thru-hole of a bone plate, or in a bushing that is disposed within a thru-hole of a bone plate, for engaging a bone screw. The annular feature can be configured such that it allows the bone screw to be inserted through the thru-hole at various insertion angles while still being effective to prevent back-out of the bone screw, thereby locking the screw to the plate.Type: GrantFiled: March 10, 2014Date of Patent: April 26, 2016Assignee: DePuy Synthes Products, Inc.Inventors: Michael Jacene, Jonathan Fanger, John R. Hawkins

Patent number: 8641734Abstract: A Posterior Dynamic Stabilization (PDS) device that regulates physiologic spinal elongation and compression. Regulation of elongation and compression are critical requirements of Posterior Dynamic Stabilization devices. Elongation and compression of the device allow the pedicles to travel naturally as the spine flexes and extends. This interpedicular travel preserves a more natural center of rotation unlike some conventional PDS devices that simply allow bending. The device incorporates two components: 1) a spring that allows elongation/compression, and 2) a polymer core component that serves to increase the stiffness of the device in shear, bending, and tension, and also prevents soft tissue ingrowth.Type: GrantFiled: April 29, 2009Date of Patent: February 4, 2014Assignee: Depuy Synthes Products, LLCInventors: Missoum Moumene, Payman Afshari, Jonathan Fanger, Kevin Flaherty
