15. A method of occluding an abnormal opening formed in tissue, comprising the steps of:
-
(a) implanting an occlusion device in the opening; and
(b) delivering expansion fluid into the occlusion device so as to expand the occlusion device to a deployed position, wherein the occlusion device fills in the opening to prevent flow through the opening; and
(c) simultaneously with step (a), monitoring displacement of the expansion device. - View Dependent Claims (16, 17, 18, 19)

20. A surgical kit comprising:
-
a delivery/guide assembly including an outer guiding catheter displaceable toward the opening and a cannula configured to be traversed by expansion medium and displaced through the guiding catheter to extend across the opening; and
a plurality of occlusion devices configured to have different shapes and dimensions and selectively and removably attachable to a distal end of the cannula, each of the occlusion devices being configured to receive the expansion medium and expand to a deployed position, wherein a periphery of the occlusion device sealingly presses against a wall of the opening.
