Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
230 words
A method for repairing an abdominal aortic aneurysm--in an aorta having two iliac arteries associated therewith, comprising the steps of: (a) connecting a tube to a first expandable and deformable, tubular member having a smooth outer wall surface, by disposing a first portion of the tubular member within the tube and disposing a second portion of the tubular member outside the tube, the tubular member having a first diameter which permits intraluminal delivery of the tubular member into the aorta; (b) disposing the tube and tubular member upon a catheter having an expandable, inflatable portion with the tubular member disposed upon the expandable, inflatable portion; (c) intraluminally delivering the tube, tubular member and catheter to the aorta and disposing at least a portion of the tube within the abdominal aortic aneurysm; and (d) expanding the expandable, inflatable portion of the catheter to expand and deform the tubular member to a second, expanded diameter, which diameter is variable and dependent upon the force applied to the tubular member, and to force the tubular member radially outwardly to force the second portion of the tubular member into contact with the aorta to secure the tubular member and at least a portion of the tube within the aorta, without perforating the aorta by the expansion and deformation of the tubular member, whereby the tube provides a fluid passageway through the abdominal aortic aneurysm.
Claim 2
Independent Claim
230 words

Dependent Claim
51 words
The method of claim 2, including the steps: connecting an expandable and deformable tubular member to each of the tubular passageways; disposing each tubular member within an iliac artery; expanding and deforming each tubular member with the catheter to secure each tubular member and associated fluid passageway within an iliac artery.
Claim 5
Dependent Claim
17 words
The method of claim 1, including the step of providing a biologically inert coating on the tube.
Claim 6
Dependent Claim
24 words
The method of claim 1, including the step of utilizing a tube made of a material which is impervious to the flow of fluid.
Claim 7
Dependent Claim
19 words
The method of claim 1, including the step of utilizing a tube made of a material which is bioerodable.
Claim 8
Dependent Claim
19 words
The method of claim 1, wherein the tube, tubular member, and catheter are intraluminally delivered through a femoral artery.
Claim 9
Dependent Claim
19 words
The method of claim 1, wherein the tube, tubular member, and catheter are intraluminally delivered through an axillary artery.
Claim 10
Dependent Claim
75 words
The method of claim 1, wherein the tubular member includes a second expandable and deformable tubular member flexibly interconnected to the first tubular member by at least one connector member, one of the tubular members being disposed above renal arteries in fluid communication with the aorta, the other tubular member being connected to the tube and disposed below the renal arteries, both tubular members being expanded and deformed to secure the tube within the aorta.
Claim 11
Dependent Claim
27 words
The method of claim 1, including the step of crimping the tube to form an undulating, longitudinal cross-sectional configuration to minimize kinking or twisting of the tube.
Claim 12
Dependent Claim
43 words
The method of claim 1, wherein the expandable and deformable, tubular member has a length, wherein the tube is connected to the expandable and deformable, tubular member by overlapping and covering a portion of the length of the expandable and deformable, tubular member.
Claim 13
Dependent Claim
27 words
The method of claim 11, including the step of overlapping and covering approximately 50% of the length of the expandable and deformable, tubular member with the tube.
