Abstract: A method and apparatus for suture-less placement of an occluding patch in which release of the device can be accelerated. In one embodiment, an inactive form of an adhesive is applied on the area of the patch that will come into contact with cardiac tissue; this allows for the introduction and necessary manipulation of the catheter system until activation of the adhesive occurs. In accordance with one aspect of the invention, the adhesive properties of certain polymeric materials are relied upon rather than their ability to cure or harden into a specific shape. In another embodiment, the patch is immediately released utilizing a detaching mechanism on the balloon or the balloon catheter which supports the patch; the patch along with the inflated balloon remain on the cardiac structure occluding the opening.
