Patent ID: 7824433

Claim:
A bone anchored device, comprising a surgical mesh having a length parallel to a longitudinal axis and a width orthogonal to the longitudinal axis sized for covering a portion of a spinal dura, lateral edges in opposition to one another sized for attachment to surrounding bone, a plurality of anchoring members disposed along the lateral edges, each anchoring member having at least one opening surrounded by a periphery, the at least one opening of the anchoring members sized to slidingly connect with at least one bone fastener and elongated to allow variable placement of the at least one bone fastener along the lateral edges, and alternating segments of rigid and pliable mesh, the rigid mesh having a length parallel to the longitudinal axis and the pliable mesh having a length parallel to the longitudinal axis such that each rigid segment is elongated parallel to the longitudinal axis and each pliable segment is elongated parallel to the longitudinal axis, and the mesh resembling the anatomic structure of a natural rigid lamina alternating with a pliable ligamentum flavum, at least the segments of rigid mesh providing a shield to protect a spinal dura, the alternating arrangement permitting motion to occur in the pliable segments located between the rigid segments.
