Abstract
A spinal fixation device comprises attachment component, seat, seat fastener, and saddle. The attachment component secures the fixation device to bone. The seat comprises an inner seat surface, an outer seat surface, a brace canal along the inner seat surface, and a channel or lip at the outer seat surface. The seat fastener has a cooperating lip or channel at an inner surface. The saddle is between a brace member and the seat fastener. The channel and cooperating lip of the seat and seat fastener cooperatively engage the seat to the seat fastener, whereby tightening the lip and channel to each other compresses the saddle between the seat and seat fastener, thereby to lock the brace member to the seat. The cooperative engagement between lip and channel is preferably achieved by rotating the seat fastener approximately 90 degrees with respect to an axis which extends perpendicular to the brace fastener.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
