Abstract
Systems methods and devices address and ameliorate intralumenal aneurysms by excluding the same through endograft by pass techniques. Percutaneuous emplacement, use of improved aortic-stent assemblies and shotgun neck framing facilitates placement of modular graft sections, for example, to treat abdominal aortic aneurysms.
Claims20
A bifurcated endograft for aneurysm treatment comprising, in combination:
- a system which can be delivered percutaneously through a 12 Fr. or less vascular introducer further comprising;
- at least an endograft element capable of being, disposed within a primary stent assembly inside of the aorta.
A modular two-piece abdominal aortic endograft system with D-shaped proximal ends and circular distal ends which can be axially aligned within the aorta;
- wherein each said modular piece is independently adjustable up and down relative to each other to accommodate the naturally anatomically variable orientation of the renal arteries.
A method of constructing a modular quasi-customizable endovascular graft in situ, comprising in combination the steps of:
- translumenally advancing a first deployment catheter to access the aorta;
- deploying a tubular cuff within the aorta;
- translumenally advancing a second deployment catheter to access the tubular cuff from the bottom deploying a first iliac graft within in the tubular cuff;
- translumenally advancing a third deployment catheter to access the tubular cuff the bottom;
- and,
- deploying a second iliac graft within the tubular cuff
A low-profile modular endograft system comprising, in combination:
- a cuff and at least two endograft units, each endograft unit having a lumen, a proximal end and a distal end, wherein each endograft unit comprises a flexible tubular woven wire frame having a proximal end with a generally D-shaped cross-section configured to be secured at the cuff and a distal end having a generally circular cross section-configured to be placed and fixed in each of the iliac arteries, and a seal between each of said endograft units and said cuff
