Benefits of technology

[0019] The systems and methods of the present invention may be used to treat aneurysms having a variety of geometries. While the systems and methods are particularly useful for treating aneurysms wherein the enlargement circumscribes the blood vessel (fusiform), such as most aortic aneurysms, they will also be useful for treating vari

Embodiment Construction

[0044] Referring to FIG. 1, in accordance with the principles of the present invention a scaffold 10 is placed within an aneurysm to span the length of the aneurysm between regions of relatively healthy vasculature. Scaffold 10 is illustrated in an abdominal aortic aneurysm AAA and extends from the renal arteries RA to the iliac arteries IA. The scaffold 10 is shown as a bare metal stent which may be balloon expandable or self-expanding within the aneurysm. It will be appreciated, that the scaffold could comprise a more conventional graft structure, a stent-graft structure, and could comprise barbs, hooks, staples, or other elements for anchoring the scaffold within the regions of healthy vasculature. As shown in FIG. 1, an annular aneurysmal space AS circumferentially surrounds the scaffold 10. The method and systems of the present invention are intended for at least partially and preferably substantially completely filling the aneurysmal space to reduce the risk of endoleaks and t...

Abstract

Aneurysms are treated by placing a scaffold across an aneurysmal sac to provide a blood flow lumen therethrough. An aneurysmal space surrounding the scaffold is filled with one or more expandable structures which are simultaneously or sequentially expanded to fill the aneurysmal space and reduce the risk of endoluminal leaks and scaffold migration. The expandable structures are typically inflatable and delivered by delivery catheter, optionally with an inflation tube or structure attached to the expandable structure.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] The present application claims the benefit of provisional application No. 60 / 753,327 (Attorney Docket No. 025925-001800US), filed Dec. 22, 2005, the full of disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to medical apparatus and methods for treatment. More particularly, the present invention relates to methods and systems for crossing and filling abdominal and other aneurysms. [0004] Aneurysms are enlargements or “bulges” in blood vessels which are often prone to rupture and which therefore present a serious risk to the patient. Aneurysms may occur in any blood vessel but are of particular concern when they occur in the cerebral vasculature or the patient's aorta. [0005] The present invention is particularly concerned with aneurysms occurring in the aorta, particularly those referred to as aortic aneurysms. Abdominal aor...
