A closure device closes an opening in a body cavity. The closure device includes a plurality of fibrous tissue engaging members coupled to a proximally extending elongate member, a closure sheath sized to receive the elongate member and slidable over the elongate member to move the fibrous tissue engaging members from an expanded position to a collapsed position, a delivery sheath sized to receive the closure sheath and having a distal end sized to engage the fibrous tissue engaging members in the expanded position, and a closure member having an aperture sized to receive the closure sheath.
