Publication number: 20080109083Abstract: One embodiment of a hollow spinal spacer (10) includes a curved anterior wall (11) having opposite ends (12, 13), a posterior wall (15) having opposite ends (16, 17), two lateral walls (20, 21), each integrally connected between the opposite ends (12, 13, 16, 17) of the anterior (11) and posterior (15) walls to define a chamber (30). The walls (11, 15, 20, 21) include a superior face (35) and an inferior face (40). The superior face (35) defines a first opening (36) in communication with the chamber (30) and includes a first vertebral engaging surface (37). The inferior face (40) defines a second opening (41) in communication with the chamber (30) and includes a second vertebral engaging surface (42).Type: ApplicationFiled: December 21, 2007Publication date: May 8, 2008Inventors: James Van Hoeck, Troy McDonald, Bradley Coates, Regis Haid, Stephen Heim, Kevin Foley, Eugene Eckstein

Publication number: 20060189990Abstract: In one embodiment of the invention, an anterior fixation system includes a plate defining a plurality of screw holes, a number of screws and a number of locking assemblies for fixing the screws to the plate. The system includes two bone screws, a fixed angle screw and a variable angle screw, that are configured to extend through the same screw openings in the fixation plate. The surgeon can select either the fixed or variable angled screws to be implanted with a single plate and can place either type of screw into any of the screw holes along the plate. The fixation plate according to the invention can include several screw holes in various patterns that provide the surgeon with great flexibility in the placement of bone screws depending upon the spinal anatomy and pathology. The invention further contemplates a locking assembly to lock one or more bone screws within a respective screw hole. In one embodiment, the locking assembly includes a washer that is held to the plate by a staked locking screw.Type: ApplicationFiled: January 11, 2006Publication date: August 24, 2006Inventors: Robert Farris, Jeffrey Poyner, Volker Sonntag, Regis Haid, Stephen Papadopoulos

Publication number: 20050283152Abstract: A retention system for maintaining a screw to a vertebral plate. One or more screws extend through apertures within the vertebral plate. A cavity is positioned adjacent to and overlaps into the aperture. A ring is positioned within the cavity and held in position by a cap. The cap attaches to the plate to prevent removal of the ring. The ring is deflectable between a first shape to allow the screw to be inserted and removed from the aperture, and a second shape to prevent screw back-out from the aperture. A method of using the system is also included and comprises positioning the ring within a cavity in the plate, maintaining the position of the ring to the plate by attaching a cap, inserting a screw through the aperture and attaching the plate to a vertebral member, and positioning the ring over the screw head and preventing the screw from backing-out.Type: ApplicationFiled: June 17, 2004Publication date: December 22, 2005Inventors: Gary Lindemann, Larry Gause, Robert Farris, Regis Haid, Steve Papadopoulos, Rick Sasso, Volker Sonntag, Vince Traynelis, Iain Kalfas

Publication number: 20050197660Abstract: A spinal stabilization system comprises an elongated stabilization device including a curved configuration along a longitudinal axis thereof. The elongated stabilization device includes a length and cross-section sized for positioning through a pathway formed from an opening in a lateral mass of a first vertebra and into the first vertebra, through the facet joint formed by adjacent articular surfaces of the first vertebra and an adjacent bony structure, and into the adjacent bony structure. Instruments can be provided to form the pathway and insert the stabilization device into the pathway.Type: ApplicationFiled: March 8, 2004Publication date: September 8, 2005Inventors: Regis Haid, Gregory Marik

Patent number: 6899735Abstract: A modular intervertebral prosthesis system includes first and second baseplates and an insert designed to mate to the baseplates. The baseplates include a mounting section and a intervertebral section extending away from the mounting section generally perpendicular thereto. The intervertebral section has at least one aperture passing therethrough. When installed, the insert is disposed between the intervertebral sections of the baseplates and faces the apertures. In this way, the insert is not insulated from the vertebral members, thereby allowing for osteoinduction, osteoconduction, and/or osteointegration, if desired. The insert may take the form of an articulating-type insert or a fusion-type insert, with the baseplates being operative with both types of inserts. After installation of the insert between the baseplates, the insert may be readily removed, at least initially.Type: GrantFiled: October 2, 2002Date of Patent: May 31, 2005Assignee: SDGI Holdings, Inc.Inventors: Bradley J. Coates, James E. Van Hoeck, T. Andrew Simonton, Regis Haid, Kevin Foley

Publication number: 20050055098Abstract: An intervertebral device comprises a first endplate assembly including a first exterior surface, a second endplate assembly including a second exterior surface, and a bone in-growth area located on the first exterior surface. The bone in-growth area includes an osteoconductive surface. The intervertebral device also comprises a bone in-growth indicator located on the first exterior surface and an access guide on the first endplate. The access guide is adapted for directing a revision instrument to the bone in-growth area.Type: ApplicationFiled: September 3, 2004Publication date: March 10, 2005Applicant: SDGI Holdings, Inc.Inventors: Thomas Zdeblick, Vincent Traynelis, Regis Haid, Greg Marik, Bradley Coats, Courtney Williams, Craig Squires

Publication number: 20050043740Abstract: Instrumentation and techniques for preparing vertebral members for insertion of an implant. Foundation instruments provide a reference relative to the vertebral members. The foundation devices guide the placement of one or more instruments that prepare the vertebral members. The instruments operatively align with the foundation instruments in a specific orientation to ensure proper placement relative to the vertebral members. Preparatory instruments may be used to further remove bone from the vertebral members. The preparatory instruments may be used prior to or after the other instruments. An insert is inserted and mounted to the vertebral members after the bone has been removed. A holder may be used for holding and placing the implant relative to the vertebral members.Type: ApplicationFiled: August 20, 2003Publication date: February 24, 2005Inventors: Regis Haid, Vincent Traynelis, Thomas Zdeblick, Bradley Coates, Greg Marik, Craig Squires, Courtney Williams, Linda Holmes

Patent number: 6755839Abstract: A guide and method of using the guide for positioning within a patient between vertebral members for contouring each of the members. The guide comprises a first section and a second section. A first edge is positioned along an edge of the first section, and a second edge is positioned along an edge of the second section. One or more elongated rods extend through the sections. One or both of the sections are movable along the rods to adjust a spacing between the first edge and the second edge. When positioned within the patient, the first edge is aligned along a first vertebral member and the second edge is aligned along a second vertebral manner. A manner of locking the sections is included for preventing the sections from moving relative to each other once the first and second edges are aligned within the patient.Type: GrantFiled: June 19, 2002Date of Patent: June 29, 2004Assignee: SDGI Holdings, Inc.Inventors: James E. Van Hoeck, Kevin Foley, Regis Haid, Stephen Papadopoulos, Stephen Heim
