Patent number: 9358127Abstract: The present invention provides an intervertebral implant for implantation in a treated area of an intervertebral space between vertebral bodies of a spine. The implant includes a spacer portion having an inferior and superior surface, wherein the inferior and superior surfaces each have a contact area capable of engaging with anatomy in the treated area, and the inferior and superior surfaces define a through-hole extending through the spacer body. The present invention further provides screw holes extending from a side portion to the inferior and superior surfaces of the spacer portion and a plate portion rigidly coupled to the spacer portion through a coupling means, wherein the plate portion contains screws holes for receiving screws. A screw back out prevention mechanism adapted on the plate portion and prevents the back out of screws from the screw holes.Type: GrantFiled: February 1, 2012Date of Patent: June 7, 2016Assignee: Globus Medical, Inc.Inventors: William E. Duffield, Colm McLaughlin, Jason Gray, Jamie Calverley, Mark Adams, William S. Rhoda

Publication number: 20160081698Abstract: Improved spinal instruments are provided. In particular, the present application relates to an improved rongeur that allows for multiple bites of bone to be performed in a patient before removing the rongeur from the patient. The rongeur includes a lower shaft and an upper shaft slidable relative to the lower shaft. The lower shaft and upper shaft form a jaw mechanism that can take multiple bites of bone, which can be deposited in a storage cavity formed in the upper shaft. To assist in removing the bone from within the storage cavity, an internal plunger mechanism can be provided that is actuated by a finger hold. In addition, at least portions of the upper shaft are detachable from the lower shaft such that the upper shaft can be thoroughly cleaned and re-used if desired.Type: ApplicationFiled: December 2, 2015Publication date: March 24, 2016Inventors: David C. Paul, William S. Rhoda, Donald Kolletzki

Patent number: 9289309Abstract: A vertebral implant for fusing adjacent vertebrae or for replacing vertebral bodies is disclosed. The implant is a biocompatble metal resorbable or radiolucent implant conforming substantially in size and shape with an end plate of a vertebra. The implant preferably has a wedge-shaped profile to restore disc height and the natural curvature of the spine. The top and bottom surfaces of the implant have areas with a plurality of teeth to resist expulsion and provide initial stability and areas devoid of any protrusions to receive implantation instrumentation. The implant also has a stackability feature. The implant provides initial stability needed for fusion without stress shielding.Type: GrantFiled: November 1, 2013Date of Patent: March 22, 2016Assignee: DePuy Synthes Products, Inc.Inventor: William S. Rhoda
