Abstract

A flexible dampening intervertebral spacer (100) to replace a spinal disc comprising upper and lower plates (101,103), an articulation element (102) and optional intermediate members (804,805). The articulation element has a plurality of interposed, concentric ring shaped segments (202) separated by one or more spaces (201) and one or more bridging elements (203) connecting the interposed segments. A first portion of the articulation element, preferably an innermost segment, is preferably fixedly connected to the upper plate while a second portion of the articulation element, preferably the outermost segment, is preferably connected to the lower plate to permit relative movement of the endplates by elastic deflection or flexing of the articulation element without opposed surfaces rubbing against each other.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 080497, entitled "FLEXIBLEDAMPENING INTERVERTEBRALSPACERDEVICE," the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an implant, more specifically to a joint prosthesis, more specifically to an intervertebral implant, and even more specifically to a joint prosthesis for replacing an intervertebral disc. Background technique [0004] The intervertebral discs are between adjacent vertebrae in the spine. Each spinal disc forms a cartilage joint that allows the vertebrae to move slightly and acts as a ligament to hold the vertebrae together. Due to ordinary wear and tear, a spinal disc can become damaged or displaced, creating a problem commonly known as a "herniated disc." In the past, damaged or diseased spinal discs have been treated by removing the disc and filling...
