Abstract
An apparatus and a method for occluding an aperture within a body surface, including an occlusion bag having a proximal sac and a distal sac, a delivery catheter, a guide catheter, a super-elastic wire, a release mechanism and a delivery sheath. The method of the invention includes affixing the delivery catheter to the proximal sac and then inserting the guide catheter into the delivery catheter. The super-elastic wire is attached to the release mechanism and the wire, release mechanism, occlusion bag, guide catheter and delivery catheter are inserted into a delivery sheath for transport to the aperture. After delivery, the occlusion bag is placed within the aperture and the wire is deployed within the bag. The bag and wire are repositioned if necessary, and the release mechanism is activated to release the wire. The guide catheter, delivery catheter, release mechanism and delivery sheath are then withdrawn.
