An apparatus and method of treating an aneurysm by applying to an aneurysmal 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 TM , or a clasp, or it can be heat sealed onto the vessel or sewn thereon. The band can also be in the form of a support strap with a cable-tie buckle on one end and protruding ridges on the other end, wherein the support strap contains a plurality of protruding nodules along its length on the side of the support strap that contacts the blood vessel and a channel along its length on the side of the support strap that contacts the blood vessel for those applications wherein the graft retention system contains barbs or stables that penetrate the blood vessel wall. |
