  • a plurality of anchors, each one of the plurality of anchors having a distal end tapered to a distal tip configured to pierce tissue and at least one wing configured to flex relative to each anchor;

    a driver including a plurality of pins, each pin in contact with a shoulder of a respective one of the plurality of anchors, configured to exert a driving force on the plurality of anchors, via the pins, to simultaneously drive the plurality of anchors into the tissue; and

    at least one closure element coupled to the plurality of anchors and configured to receive the driving force, to enter a deformed state based on the driving force, and to urge the plurality of anchors toward each other by an elastic tension between the plurality of anchors during the deformed state of the at least one closure element;

    wherein the at least one closure element is configured to comply with a myocardium of a beating heart without interfering with the movement of the walls of the heart, and transfer sufficient force to urge the plurality of anchors, driven into the tissue, toward each other to close an aperture in the tissue located between the plurality of anchors driven into the tissue.
