| 20090299411 | System and Method for Replacement of Spinal Motion Segment - A system for flexibly stabilizing a vertebral motion segment of the facet joint by connecting a first vertebra and a second vertebra is disclosed. The system includes an elongate connection element with end portions interconnected by a flexible coupling member. The system includes first and second attachment portions for connecting the connection element to the vertebrae. A first resilient member is positioned between the first end portion and the first attachment portion, and a second resilient member is positioned between the first attachment portion and the second attachment portion. The system is designed such that the second resilient member is compressed when the first and second attachment portions move towards each other, and the first resilient member is compressed when the first and second attachment portions extend away from each other and a part of the first and second attachment portions extend towards each other on opposing walls of the elongate connection element. | 12-03-2009 |
| 20100094343 | UNIPLANAR SCREW - A spinal stabilization system for surgical implantation in the spine having a bone fastener. The bone fastener is provided with a head portion and a shaft portion. A housing is also provided with a recess defined by sidewalls and an opening for receiving the head portion of the bone fastener. A seating element is disposed within the housing and positioned over the head portion of the bone fastener. An elongate rod is positioned on the seating element within the recess of the housing. The system also includes a cap capable of engaging with a top portion of the housing and capturing the elongate rod within the recess of the housing when the cap is rotated. The bone fastener articulates in a single plane with respect to the housing and the seat element. | 04-15-2010 |
| 20100094352 | BONE SCREW - The present invention provides a bone screw which can be used for fixation and/or fastening of prosthetic devices or instruments to bone tissue whose structure or dimensions differ from one region to another. In particular, the present invention provides a bone screw which is designed to optimize purchase in both the cancellous and cortical regions of a vertebral body. In an exemplary embodiment, the bone screw has a distal portion and a proximal portion in which the diameter of the thread on the proximal portion of the screw is greater than the diameter of the thread on the distal portion of the screw. | 04-15-2010 |
| 20100234893 | Spinal Implant Connection Assembly - The present invention provides a connection assembly that can be used to securely connect a spinal implant to a bone anchor. In particular, the present invention preferably provides a spinal implant connection assembly that is able to securely connect the spinal implant to the anchors even when there is a variance in the angle and position of the anchors with respect to the spinal implant. Furthermore, the present invention provides a connection assembly with structure to increase the locking strength of the connection assembly. | 09-16-2010 |
| 20100249856 | Devices and Methods for Inserting a Vertebral Fixation Member - A device and method for inserting a vertebral stabilization member is disclosed. The stabilization member is releasably clampable to an insertion device between first and second clamping members at a clamping location spaced from a midline of the stabilization member. The insertion device and stabilization member are deliverable through an access sleeve and the stabilization member is rotatably actuatable to position the stabilization member in relation to a bone anchor. | 09-30-2010 |
| 20100331901 | Percutaneous Vertebral Stabilization System - The present invention relates to a system for percutaneously installing a 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. | 12-30-2010 |
