Abstract: Tissue anchoring devices including a radially expandable frame having a plurality of longitudinal struts and a plurality of deployable anchors configured to penetrate a stent graft and tissue, and systems for delivering and deploying the tissue anchoring devices at a target location are provided. The adjacent longitudinal struts are interconnected by a plurality of expandable struts, and a ring of these expandable struts may be angled radially outward relative to a remainder of the expandable struts in an expanded configuration. Each of the plurality of anchors may include one or more anti-buckling mechanisms to facilitate penetration into the graft/tissue.
