First Claim
Patent Images
1. An intervertebral disc prosthesis comprising:
- two opposing plates;
a flexible seal extending between said two opposing plates for forming a closed chamber between said two plates, wherein said flexible seal is adapted for enabling said plates to move relative to one another; and
a compressible body disposed in said closed chamber and between said plates, said compressible body having a first surface in contact with a face of one of said plates, wherein an area of contact between the first surface of said compressible body and the face of said plate increases when compressive forces are exerted upon said compressible body; and
a fluid provided in said closed chamber between said two opposing plates, wherein said fluid is in contact with said plates and surrounds said compressible body.

Abstract
An intervertebral disc prosthesis comprising two opposing plates and a flexible seal extending between the two opposing plates for forming a closed chamber between the two plates, the flexible seal being adapted to enable the plates to move relative to one another. The disc prosthesis also includes a compressible body disposed in the closed chamber and located between the plates. The compressible body has a first surface in contact with a face of one of the plates, whereby an area of contact between the first surface of the compressible body and the face of the one of the plates increases when compressive forces are exerted upon the compressible body.
