US Patent 8454612 Method for vertebral endplate reconstruction

Embodiments relate generally to tissue anchors and methods of delivering same to the intervertebral disc or other sites within the body. In some embodiments, the anchors provide increased pull-out resistance, stability and/or contact with tissue involving a reduced amount of penetration. In some embodiments, delivery methods are minimally invasive and can include linear, lateral, and off-angle implantation or driving of anchors along, against or within tissue surfaces. Several embodiments disclose anchors and anchoring systems that effectively reconstruct or augment vertebral endplate surfaces.
