Abstract
The artificial spinal disc of the invention is intended to articulate in a manner resembling a human knee articulation. The artificial spinal disc includes two plates each having a planar outer surface and an articulating inner surface. The planar outer surfaces contact adjacent inferior and superior surfaces of two adjacent vertebrae having the spinal disc implanted therebetween. The planar surfaces of the plates are affixed to the adjacent vertebrae. The articulating surfaces of the artificial spinal disc will be generally bimodal-shaped such that a first articulating surface will have two convex shaped articulating portions and the second articulating surface will have two concave shaped articulating portions. The concave and convex shaped portions of the respective plates will be generally complementary. The articulation of the artificial spinal disc will generally resemble that of a human knee.

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.
