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.RTM., or a clasp, or it can be heat sealed onto the vessel or sewn thereon.
Claims17
An aortic graft assembly comprising:
- a generally liquid impervious body having a first and second end,
- a graft retention system disposed at each of said first and second ends for attaching said graft to a blood vessel,
- a support strap adapted to surround the exterior of a blood vessel, said support strap having a closure means for retaining said strap in a circular configuration when said strap is disposed around the exterior of said blood vessel at a location adjacent to each of said graft retention systems.
In a vascular graft for resolving an aneurysm in a blood vessel of the type comprising a generally liquid impervious, tubular, collapsible and expandable body having a first and second end, and a graft retention system disposed at each of said first and second ends for attaching said graft to a blood vessel, in use, said graft retention system being collapsible and expandable, the improvement comprising a support strap adapted to surround the exterior of said blood vessel, said support strap having a closure means for retaining said strap in a circular configuration when said strap is disposed around a blood vessel at a location adjacent to each of said graft retention systems.
A method of repairing an aneurytic blood vessel by inserting in said blood vessel at a location remote from the site of the aneurysm a vascular graft, positioning the graft at the site of the aneurysm, and securing said vascular graft to said blood vessel with a graft retention system, said graft retention system attaching to said blood vessel at positions on each side of said aneurysm, the improvement comprising securing around the exterior of said blood vessel at positions adjacent each of said graft retention systems, a strap wherein said strap does not penetrate said blood vessel.
