The spinal rod also includes a rounded end cap adapted to mate with at least one of the end portions. The end cap is radiopaque.Type: GrantFiled: August 31, 2006Date of Patent: August 3, 2010Assignee: Warsaw Orthopedic, Inc.Inventors: Christopher M. Patterson, Thomas Carls, Fred J. Molz, IV

Patent number: 7758617Abstract: The present invention relates to a percutaneous vertebral stabilization system. A first anchor is positionable within a body of a patient through a first percutaneous opening and a second anchor is positionable within a body of a patient through a second percutaneous opening. A stabilization member is positionable within the body of a patient through the first percutaneous opening to engage and connect the first and second anchors.Type: GrantFiled: October 6, 2005Date of Patent: July 20, 2010Assignee: Globus Medical, Inc.Inventors: Andrew Iott, Andrew Lee, Edward Karpowicz

Publication number: 20100152777Abstract: Mechanical modifications to a spinal rod that will enable the rod to accept various coating technologies in such a way that the spinal construct's biomechanical performance is not compromised. These modifications preserve construct biomechanics in the presence of a coating and increase the bactericidal payload of an anti-infective spinal rod coating.Type: ApplicationFiled: December 16, 2008Publication date: June 17, 2010Inventors: Michael A. Fisher, Paul Birkmeyer, Hassan Serhan, Jeffrey Sutton, Uri Herzberg, Ikshoo Chun, Raymond S. Shissias

Patent number: 7713287Abstract: A dynamic spine stabilization device is provided that includes at least one force imparting member, e.g., a spring. The force imparting member is adapted to deliver a force of between about 150 lb/inch and 450 lbs/inch, and restrict the relative travel distance between said first and second pedicles to a distance of between about 1.5 mm and 5 mm. The spinal stabilization devices also have a minimal impact on the location of the center of rotation for the spinal segment being treated. By providing resistance in the noted range and restricting the travel distance to the noted range, it has been found that the stabilization device provides a desired level of stabilization, as reflected by range of motion values that closely approximate pre-injury range of motion levels.Type: GrantFiled: May 19, 2005Date of Patent: May 11, 2010Assignees: Applied Spine Technologies, Inc., Yale UniversityInventors: Jens Peter Timm, Manohar M.
