1. An apparatus for reversibly closing a septal defect, the apparatus comprising:

  • a) a septal defect closure device that is unitary in construction and comprises a first end, a second end and a center portion, said septal defect closure device having a first configuration comprising a scored, cylindrical shaft having an axis therethrough;

    b) a catheter delivery means; and

    c) an intralumen mechanical mechanism located in the catheter delivery means;

    whereby when the device is delivered to an area having a septal defect such that the center portion of the shaft is positioned in the defect, at least two support struts are created as the intralumen mechanical mechanism begins to pull the first and second ends of the shaft toward the center portion thereof, the struts moving radially away from the axis in a hinge like fashion, thereby causing the septal defect closure device to assume a specific second configuration which fits securely into the septal defect and spans both sides of the septal defect, said septal defect closure device in its second configuration being anchored to the septal defect by pressure, causing the defect to be reversibly closed.
