Publication number: 20120010661Abstract: Embodiments of an orthopedic implant device and system, and methods for implanting them, are disclosed. The implant may include a receiver member having a channel for accommodating an elongated rod or other longitudinal member, a bone anchoring member such as a screw or hook, and a base member rotatable with respect to the receiver member for retaining the bone anchoring member in the receiver member. The base member is configured to allow at least two different degrees of maximum angulation of the bone anchoring member with respect to the receiver member. The number and relative direction of such angulations are independent of the orientation of the channel or other part of the receiving member.Type: ApplicationFiled: September 19, 2011Publication date: January 12, 2012Applicant: Warsaw Orthopedic, Inc.Inventors: Robert A.

Publication number: 20100222780Abstract: A retention system for maintaining a screw to a vertebral plate is described herein. 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.Type: ApplicationFiled: May 11, 2010Publication date: September 2, 2010Applicant: Warsaw Orthopedic, Inc.Inventors: Gary S.

Publication number: 20100222822Abstract: A posterior fixation system includes a saddle member, an anchoring member, an occipital plate, an occipital rod, and a cross-link connector. The anchoring member anchors the saddle member to bone. The saddle member includes a pair of upright portions that define a channel. The channel is adapted to receive an orthopedic rod, and the saddle member can include a hole to receive the anchoring member. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members. The anchoring member in one embodiment is a screw coupled to the hole of the saddle, and in another embodiment, the anchoring member is a hook. The offset member may be coupled to the saddle member to allow for offset connection of rods. Connection of individual rods can be accomplished by connecting the rods with the cross-link connector. The cross-link connector has an integrally formed cylindrical member that couples a pair of coupling portions together.Type: ApplicationFiled: March 1, 2010Publication date: September 2, 2010Applicant: WARSAW ORTHOPEDIC, INC.Inventors: Robert A. Farris, Kevin T. Foley, Stephen M. Papadopoulos, Jeffrey Wade Poyner, Ricardo Sasso

Patent number: 7749256Abstract: Devices and methods for spinal fixation employ at least first and second plates that are configured to allow progressive sliding advancement of the plate members toward one another and limit movement of the plate members away from one another after installation. A spring member associated with one bone plate may engage toothed section(s) on the other bone plate. The bone plates may each have arms that are spaced from one another and engaged by corresponding arms on the other bone plate. There may be more than two bone plates, with multiple restricted movement regions.Type: GrantFiled: April 5, 2005Date of Patent: July 6, 2010Assignee: Warsaw Orthopedic, Inc.Inventors: Robert A. Farris, Jason M. May, Alexander R. Vaccaro

Patent number: 7744634Abstract: A spinal rod system includes a first rod and a second rod engaged to one another in end-to-end fashion. The first and second rods include rod portions with differing characteristics, and a coupling mechanism allows the spinal rod system to be assembled with rod portions having the desired characteristics while minimizing the footprint of the coupling arrangement between the first and second rods.Type: GrantFiled: June 15, 2004Date of Patent: June 29, 2010Assignee: Warsaw Orthopedic, Inc.Inventor: Robert A.

Publication number: 20100152780Abstract: Devices and methods for anchoring one or more elongate connecting members along the spinal column include a transverse linking member positionable through a spinous process in a generally orthogonal orientation to the sagittal plane. At least one coupling assembly is engageable about an end of the linking member extending from the spinous process. The elongate connecting member is engaged to the coupling assembly in a transverse orientation to the transverse linking member.Type: ApplicationFiled: February 26, 2010Publication date: June 17, 2010Applicant: WARSAW ORTHOPEDIC, INC.Inventors: Kevin L.

Patent number: 7523713Abstract: This invention gives the directions for the design and building of a vehicle which will be supported in water by the installation of a Floatation Material. The design is so that the vehicle, occupants, and cargo will be supported so that the vehicle will come to rest in the upright position and with the water level below the upper torso of the occupants. There are several demonstrations presented on a regular basis which show how to escape from a vehicle that has suddenly become immersed in water: a lake, river, etc. Escaping is portrayed as a fairly simple procedure when performed by someone who is coached through the process, and by an individual who knows the vehicle is supported by a crane. The design presented in this invention provides a vehicle that will float while requiring no effort from the occupants, nor does it depend on the performance of some mechanism, i.e. switches, relays, or some mechanically activated procedure that requires intervention by the occupant.Type: GrantFiled: May 7, 2007Date of Patent: April 28, 2009Inventor: Robert Farris
