Abstract
Abstract An apparatus for endovascular repair of aortic aneurysms is disclosed. In one form, the apparatus includes a tube and an anchoring unit that includes a plurality of thin lines. The tube serves as a conduit for blood flow in an aneurysm of an aorta. A first end of the plurality of lines is connected to a first end of the tube. A second end of the plurality of lines is separated by a distance from the first end of the tube for anchoring the apparatus at a location away from the aneurysm.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
An apparatus for repairing an aneurysm of an aorta, the aorta including a region from which celiac, mesenteric and renal arteries originate, the aneurysm being located along a section of the aorta positioned between the renal and iliac arteries, the apparatus including: a) a tube to serve as a conduit for blood flow in the aneurysm of the aorta, the tube being dimensioned in length to at least extend a length of the aneurysm and to terminate below the renal arteries; b) an anchor, separated by a distance from the tube, to secure the apparatus within the aorta; and c) a plurality of thin lines interconnecting the anchor and the tube, the lines being dimensioned to a length greater than a length of the region of the aorta from which the celiac, mesenteric and renal arteries originate, each of the lines being sufficiently thin so as to not obstruct blood flow to the celiac, mesenteric and renal arteries, the plurality of thin lines including more than 2 thin lines.
Claim 2
Independent Claim
169 words
An apparatus for repairing an aneurysm of an aorta, the aorta including a region from which celiac, mesenteric and renal arteries originate, the aneurysm being located along a section of the aorta positioned between the renal and iliac arteries, the apparatus including: a) a tube to serve as a conduit for blood flow in the aneurysm of the aorta, the tube being dimensioned in length to at least extend a length of the aneurysm and to terminate below the renal arteries; b) an anchor, separated by a distance from the tube, to secure the apparatus within the aorta; and c) a plurality of thin lines interconnecting the anchor and the tube, the lines being dimensioned to a length greater than a length of the region of the aorta from which the celiac, mesenteric and renal arteries originate, each of the lines being sufficiently thin so as to not obstruct blood flow to the celiac, mesenteric and renal arteries, the plurality of thin lines including more than 2 thin lines.
Claim 3
Dependent Claim
15 words

Claim 12
Dependent Claim
28 words
The apparatus of claim 1 , wherein the apparatus can be implanted without regard to the rotational orientation of the apparatus about a longitudinal axis of the aorta.
Claim 13
Independent Claim
195 words
A method for repairing an aneurysm of an aorta, the aorta including a region from which celiac, mesenteric and renal arteries originate, the aneurysm being located along a section of the aorta positioned between the renal and iliac arteries, the method comprising: A) providing an apparatus including: a) a tube to serve as a conduit for blood flow in the aneurysm of the aorta, the tube being dimensioned in length to at least extend a length of the aneurysm; b) an anchor, separated by a distance from the tube, to secure the apparatus within the aorta; and c) a plurality of thin lines interconnecting the anchor and the tube, the lines being dimensioned to a length greater than a length of the region of the aorta from which the celiac, mesenteric and renal arteries originate, each of the lines being sufficiently thin so as to not obstruct blood flow to the celiac, mesenteric and renal arteries, the plurality of thin lines including more than 2 thin lines; and B) implanting the apparatus in the aorta with an uppermost portion of the tube terminating below the renal arteries and the anchor secured above the celiac artery.
Claim 14
Independent Claim
195 words
