Abstract
Abstract The present invention is an apparatus and method of treating an aneurysm by applying to an aneurytic blood vessel a band around its exterior surface, at the position where the attachment system of the graft attaches the graft to the vessel. The band can be in the form of a strap with an attachment means such a Velcro®, or a clasp, or it can be heat sealed onto the vessel or sewn thereon.
