1. A method for closing a bodily passageway in a patient, the method comprising:

  • providing a closure device assembly, the closure device assembly comprising;

    a delivery catheter housing;

    a delivery release member; and

    a collapsibly disposed closure device, the closure device comprising;

    a first frame comprising at least one hollow tube;

    a sheet of biocompatible material attached to the first frame;

    a first crossbar extending across the first frame, the first crossbar having terminal crossbar ends connectively linked to separate sites on the first frame;

    a second crossbar attached to the first crossbar at a connection point; and

    a second frame comprising at least one hollow tube, the second crossbar extending across the second frame, the second crossbar having terminal crossbar ends connectively linked to separate sites on the second frame,wherein the first crossbar and the second crossbar each comprise at least one hollow tube and are each configured to bend away from the connection point when the closure device is deployed to close a bodily passageway;

    wherein at least one first retention member extends through a lumen of the hollow tube of the first frame and connects the first crossbar to the first frame,wherein at least one second retention member extends through a lumen of the hollow tube of the second frame and connects the second crossbar to the second frame;

    advancing the delivery catheter housing through the bodily passageway;

    releasing the first frame from the delivery catheter housing proximate to a first opening of the bodily passageway;

    retracting the delivery catheter housing through the bodily passageway and positioning the delivery catheter housing proximate to a second opening of the bodily passageway; and

    disengaging the closure device from the delivery release member and releasing the second frame proximate to the second opening of the bodily passageway,wherein the closure device is secured to tissue portions surrounding the bodily passageway, thereby closing the bodily passageway.
