Claim 8
Dependent Claim
24 words
The aortic graft of claim 7, wherein the two tubular passageways include means for securing the two tubular passageways to the two illiac arteries.
Claim 9
Dependent Claim
164 words
The aortic graft of claim 8, wherein the securing means includes a thin-walled tubular member having first and second ends and a smooth outer wall surface disposed between the first and second ends, the wall surface having a substantially uniform thickness and a plurality of slots formed therein, the slots being disposed substantially parallel to the longitudinal axis of the tubular member, the fluid passageways being secured to the first end of the tubular member; the tubular member having a first diameter which permits intraluminal delivery of the tubular member into the aorta and the tubular member having a second, expanded and deformed diameter, upon the application from the interior of the tubular member of a radially, outwardly extending force, which second diameter is variable and dependent upon the amount of force applied to the tubular member, whereby the tubular member may be expanded and deformed to secure the second end of the tubular member and the tubular passageways to the two illiac arteries.
Claim 10
Dependent Claim
28 words
The aortic graft of claim 1, wherein the first end of the tube is secured to the second end of the tubular member by a plurality of sutures.
Claim 11
Dependent Claim
51 words
The aortic graft of claim 1, wherein the first end of the tube which is secured to the second end of the tubular member is radially expandable, whereby the first end of the tube may conform with the second expanded and deformed diameter of the second end of the tubular member.
Claim 12
Dependent Claim
19 words
The aortic graft of claim 2, wherein the tube has an intermediate portion which is not substantially radially expandable.
Claim 13
Dependent Claim
27 words
The aortic graft of claim 1, wherein the tube is crimped to form an undulating longitudinal cross-sectional configuration, whereby kinking or twisting of the tube is minimized.
Claim 14
Dependent Claim
38 words
The aortic graft of claim 1, wherein the securing means includes first and second tubular members flexibly interconnected by at least one connector member, the first end of the tube being secured to one of the tubular members.
Claim 15
Dependent Claim
11 words
The aortic graft of claim 1, wherein the tube is bioerodable.
Claim 16
Dependent Claim
23 words
The aortic graft of claim 1, wherein the tube is impervious to the flow of fluid through the wall surface of the tube.
Claim 17
Dependent Claim
202 words
An aortic graft for intraluminal delivery to repair an abdominal aortic aneurysm in an aorta having two illiac arteries associated therewith, comprising: (a) a tube having first and second ends and a wall surface disposed between the two ends, at least a portion of the tube adapted to be disposed within the abdominal aortic aneurysm; (b) means for securing the first end of the tube to the aorta, the securing means including a thin-walled member having first and second ends and a smooth outer wall surface disposed between the first and second ends of the thin-walled member, the first end of the tube being connected to the second end of the thin-walled member, the thin-walled member having a first diameter which permits intraluminal delivery of the thin-walled member into the aorta, the thin-walled member having a second, expanded and deformed diameter, upon the application from the interior of the thin-walled member of a radially, outwardly extending force, which second diameter is variable and dependent upon the amount of force applied to the thin-walled member, whereby the thin-walled member may be expanded and deformed to secure the first end of the thin-walled member and the first end of the tube to the aorta.
Claim 18
Dependent Claim
19 words
The aortic graft of claim 17, wherein the thin-walled member has a biologically inert coating on its wall surface.
Claim 19
Dependent Claim
49 words
The aortic graft of claim 17, wherein the second end of the tube is bifurcated and two tubular passageways are formed which are in fluid communication with the first end of the tube and the two passageways are adopted to be mated with and disposed within two illiac arteries.
Claim 20
Dependent Claim
24 words
The aortic graft of claim 19, wherein the two tubular passageways include means for securing the two tubular passageways to the two illiac arteries.
Claim 21
Dependent Claim

Claim 22
Independent Claim
158 words
An apparatus for repairing an abdominal aortic aneurysm in an aorta having two illiac arteries associated therewith, comprising: (a) a tube having first and second ends and a wall surface disposed between the two ends; (b) an expandable and deformable thin-walled tubular member, having first and second ends and a smooth outer wall surface disposed between the first and second ends, the first end of the tube being secured to the second end of the tubular member, the expansion and deformation of the thin-walled tubular member being controllable; and (c) a catheter having an expandable, inflatable portion associated therewith, the thin-walled tubular member being releasably mounted upon the inflatable portion of the catheter, whereby upon inflation of the expandable, inflatable portion of the catheter, the thin-walled tubular member is forced radially outwardly into contact with the aorta to remain secured thereto, whereby the tube, secured to the thin-walled tubular member, provides a passageway through the abdominal aortic aneurysm.
