Abstract:
1. An artificial intervertebral disc, comprising: a first anchor member; a second anchor member, the first and second anchor members having opposing internal surfaces facing one another; at least a first dome element with at least one curved face; and a composite structure; wherein the composite structure is comprised of a column comprising ePTFE and a column filler comprising an elastomer; wherein the composite structure is disposed between the opposing internal surfaces of the first anchor member and the second anchor member with the first dome element between at least a portion of the column filler and the internal surface of the first anchor member such that a curved interface exists between the first dome element and the column filler and such that movement of the first anchor member and second anchor member relative to one another causes the first dome element to move relative to the column filler and such that the first dome element has convex curvature that corresponds to a concave curvature of the column filler; and wherein the curved interface is spaced apart from the internal surface of the second anchor member.
