Abstract
An endoluminal prosthesis for treatment of a condition in a lumen in the vicinity of a branch lumen, the lumen being adapted to resist migration, is provided. In one embodiment, the prosthesis includes a substantially tubular main stent adapted for placement in the main lumen. A substantially tubular anchor stent is connected to the main stent and adapted for placement in the branch lumen.
Claims17
An endoluminal prosthesis for treatment of a condition in a lumen in the vicinity of a branch lumen, said prosthesis adapted to resist migration, said prosthesis comprising:
- a substantially tubular main stent adapted for placement in the main lumen;
- and
- a substantially tubular anchor stent connected to said main stent and adapted for placement in the branch lumen.
A method of endoluminally deploying an endovascular prosthesis for treatment of an abdominal aortic aneurysm, the prosthesis being adapted to resist migration and comprising a main stent adapted for placement below the renal arteries and an anchor stent adapted for placement in a renal artery and pivotally connected to the main stent, said method comprising the steps of:
- advancing a first guide wire for the anchor stent through the renal artery;
- advancing a second guide wire for the main stent through the aorta;
- advancing the main stent over the first guide wire to endoluminally position the prosthesis at a preselected position in the aorta;
- pivoting and advancing the anchor stent over the second guide wire into position within the renal artery;
- expanding the anchor stent within the renal artery;
- and
- expanding the main stent within the aorta.
