Abstract

A vascular occlusion assembly for therapeutically occluding a vascular site in a patient. The assembly comprises a foldable material occlusion bag having an expanded diamond shape and an elongated flexible filler member which is inserted in the internal cavity of the occlusion bag. When positioned in the internal cavity of the bag, the filler member assumes a convoluted configuration expanding the bag to the expanded shape. The occlusion bag is positioned on the flared distal end of a positioning catheter. A collar is wrapped around the neck of the bag to securely position the bag and prevent premature detachment from the positioning catheter. A pusher catheter is coaxially positioned around the positioning catheter to release the expanded occlusion bag from the flared distal end of the positioning catheter. A handle is releasably attached to the proximal end of the flexible filler member and inserted into the positioning catheter for expanding the occlusion bag to the diamond shape. The distal portion of the filler member is hook-shaped for readily inserting the filler member in the bag without tearing the bag. The distal end segment of the filler member is also enlarged to minimize perforation of the bag and prevent withdrawal through the positioning catheter.
