Methods For Augmenting A Vertebra With A Device Including An Expandable Implant And Anchoring Elements For Anchoring The Device Within A Vertebral Pedicle

Abstract

Methods for augmenting a vertebra with a device including an expandable implant and a pedicle anchor. The pedicle anchor includes at least one anchoring element movably coupled to an anchor body. An actuator is movable within the anchor body to deploy the anchoring element into engagement with a vertebral pedicle. The anchoring element may be deployed in a same plane as a tissue support ski of the expandable implant. The actuator may be a rod including a knuckle or a cam. The tissue support ski may be recessed from an outer profile of the device. Struts of the expandable implant may be angled towards the tissue support ski in an insertion configuration. The device may be oval-shaped and provide means for rotating the expandable implant relative to the pedicle anchor, and for blocking the expandable implant in a predetermined orientation.

Dependencies are inferred from the claim text.
