20080312698 | DEVICE AND SYSTEM FOR STABILIZING MOVEMENT BETWEEN BONY TISSUE AND METHOD FOR IMPLANTING - A device and system for stabilizing movement between two or more vertebral bodies and methods for implanting. Specifically, embodiments of the present disclosure may provide medical professionals the ability to selectively position and orient anchors in bony tissue and then attach a plate to the pre-positioned anchors. The plate assembly, once positioned on the anchors, prevents the anchors from backing out of the bony tissue. | 12-18-2008 |
20090093843 | DYNAMIC SPINE STABILIZATION SYSTEM - Disclosed are devices and systems for spinal fixation and dynamic stabilization. Elongated members may be positioned lateral to spinous processes and coupled to two or more vertebrae. Interspinous members may be positioned between adjacent spinous processes and coupled to the elongated members. One embodiment of an interspinous member comprises a body and two lateral portions. The lateral portions may couple to the elongated members to position the interspinous members. An interspinous member and the positioning of the interspinous member may allow selected movement between the adjacent spinous processes. | 04-09-2009 |
20090138044 | STABILIZATION SYSTEM AND METHOD - The disclosure relates to systems and methods of spinal stabilization. Embodiments include methods of delivering a rod having a non-circular cross-sectional profile using a wire having an accommodating non-circular cross-sectional profile to inhibit movement of a rod relative to the wire. A surgical system can comprise a first sleeve advanced via a first incision to a vertebra, a second sleeve advanced via a second incision to another vertebra, a wire having a non-circular cross-sectional profile advanced via a third incision to the vertebrae and passed through the collars of bone fastener assemblies to extend from a fourth incision. A rod or a segment of a rod having a corresponding non-circular cross-sectional profile may be aligned with the wire and advanced and coupled with the vertebrae to stabilize the spine. After the rod is securely seated in the collars, the wire may be withdrawn from the body. | 05-28-2009 |
20090312801 | MULTI-GUIDE PLATE HOLDER - Methods, instruments, and kits for attaching cranial plates. One embodiment implements a method which includes releasably attaching a plate to an instrument (using retaining members of the instrument) and placing the plate on a cranium (using an elongated and offset handle of the instrument). The method can include drilling a hole in the cranium, tapping the hole, and placing the screw in the hole using the instrument which defines a pattern of holes corresponding to, a pattern of holes on the plate. The drilling of the hole, tapping of the hole, and placing of the screw can occur by engaging one of the instrument holes with, respectively, a drill bit shank, a tap shank, and a screw head having a common diameter corresponding to a diameter of the instrument hole. The method can include selecting the plate, the drill bit, the tap, and the screw from a kit. | 12-17-2009 |
20090326589 | HINGED PLATE FOR DYNAMIC STABILIZATION - One embodiment provides a system which can include a pair of plates pivotably coupled to each other by a hinge. The plates can attach to posterior surfaces of vertebrae. The posterior surfaces can be on vertebral facets or can be exposed by removal of the facets. The hinge can be coupled to the plates in such a manner that the hinge is positioned adjacent to a center of rotation about which the vertebrae rotate relative to each other when the spine extends or flexes. The hinge can include a ball and socket, pin and pin hole, screw, etc and a sealing jacket. The system can include a piston for allowing the system to stretch and compress with the spine. Travel stops can be included in the hinge and piston. Multiple levels of the spine can be stabilized by systems with pairs of plates keyed to align with each other. | 12-31-2009 |
20100004686 | TAPERED-LOCK SPINAL ROD CONNECTORS AND METHODS FOR USE - A spine stabilization system having cylindrical bodies, plates, transverse members and resilient inserts for coupling a rod to bone fasteners. A first resilient insert may be positioned on a first rod. A cylindrical body, plate or transverse member may be positioned on the first resilient insert such that the first resilient insert is in a passage. A second resilient insert may be positioned on a second rod and positioned in the cylindrical body, plate or transverse member. The resilient inserts are advanced into the cylindrical body, plate or transverse member to lock the resilient inserts in place and couple the rods. | 01-07-2010 |
20100004693 | CAM LOCKING SPINE STABILIZATION SYSTEM AND METHOD - A spine stabilization may include a rod and bone fastener assemblies. Each bone fastener assembly may include a bone fastener and a collar. Each bone fastener may have a threaded shank and a head. Each collar may have a first end with a cavity for accommodating the bone fastener and a second end having a channel for accommodating the rod. The channel may have a first portion for positioning the rod. The channel may have a second portion for advancing the rod, wherein rotating the collar advances the rod in the channel. | 01-07-2010 |
20110190823 | STABILIZATION SYSTEM AND METHOD - The disclosure relates to systems and methods of spinal stabilization. Embodiments include minimally invasive methods of delivering a rod having a non-circular cross-sectional profile using a wire having an accommodating non-circular cross-sectional profile to inhibit movement of the rod relative to the wire. A rod or a segment of the rod having a non-circular cross-sectional profile may be aligned with the wire and advanced and coupled to bone fastener assemblies which are anchored in vertebrae. The rod is then securely seated in collars of the bone fastener assemblies to stabilize the spine. | 08-04-2011 |
20130331891 | STABILIZATION SYSTEM AND METHOD - The disclosure relates to systems and methods of spinal stabilization. Embodiments include minimally invasive methods of delivering a rod having a non-circular cross-sectional profile using a wire having an accommodating non-circular cross-sectional profile to inhibit movement of the rod relative to the wire. A rod or a segment of the rod having a non-circular cross-sectional profile may be aligned with the wire and advanced and coupled to bone fastener assemblies which are anchored in vertebrae. The rod is then securely seated in collars of the bone fastener assemblies to stabilize the spine. | 12-12-2013 |
