Abstract: A tissue anchoring device including an expandable frame and at least one anchor having a tissue penetrating portion. The anchor is attached to the expandable frame through a plurality of beams forming a frame or a tab that enable the anchor to elastically bend with respect to a longitudinal axis of the expandable frame.
