Abstract
Abstract Disclosed is a method for excluding a pathological defect such as an aortic aneurysm. By the disclosed method, a grafstent complex is advanced through each branch of the patient's femoral and iliac system. The graftstent complex includes a segment of graft material attached at each end to a respective stent. The cephalic stents of each graftstent complex are positioned relative to one other in a common region of normal aortic tissue on one side of the aneurysm and then deployed. The caudal stents are deployed in the iliac arteries. Additional steps can be taken to ensure that the internal iliac artery is not blocked when the caudal stents are deployed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
47 words
An intraluminal delivery system, comprising: a delivery sheath; a catheter slidably positioned within the delivery sheath; and a graftstent complex which includes a self-expanding stent, a second stent, and a graft connected between the stents, the graftstent complex being supported on the catheter within the delivery sheath.
Claim 2
Dependent Claim
47 words
An intraluminal delivery system, comprising: a delivery sheath; a catheter slidably positioned within the delivery sheath; and a graftstent complex which includes a self-expanding stent, a second stent, and a graft connected between the stents, the graftstent complex being supported on the catheter within the delivery sheath.
Claim 3
Dependent Claim
16 words
The intraluminal delivery system of claim 1 , wherein the second stent is a mechanically-expandable stent.
Claim 4
Dependent Claim
25 words
The intraluminal delivery system of claim 1 , wherein the expansion catheter is a balloon catheter and wherein the radially-expandable element is an inflation balloon.
Claim 5
Dependent Claim
71 words
An intraluminal delivery system, comprising: a delivery sheath; an expansion catheter having a radially-expandable element, the expansion catheter being slidably positioned within the delivery sheath; and a graftstent complex which includes a mechanically-expandable stent, a self-expanding stent and a graft connected between the stents, the mechanically-expandable stent being supported on the radially-expandable element while the graft and self-expanding stent are seated proximal to the radially-expandable element and within the delivery sheath.
Claim 6
Dependent Claim
71 words
An intraluminal delivery system, comprising: a delivery sheath; an expansion catheter having a radially-expandable element, the expansion catheter being slidably positioned within the delivery sheath; and a graftstent complex which includes a mechanically-expandable stent, a self-expanding stent and a graft connected between the stents, the mechanically-expandable stent being supported on the radially-expandable element while the graft and self-expanding stent are seated proximal to the radially-expandable element and within the delivery sheath.
Claim 7
Independent Claim
103 words
A method for endoluminally excluding an aortic aneurysm in a patient's vascular system, comprising the steps of: advancing through each branch of the patient's femoral and iliac system a respective graftstcnt complex, each graftstent complex comprising a first stent, a second stent and a graft connected between said first and second stents, said second stent being a self-expanding stent; positioning said first stents relative to each other in a common region of normal aortic tissue on one side of the aneurysm; deploying each of said positioned first stents in the common region; and deploying each of said second stents in the iliac arteries.
Claim 8
Independent Claim
103 words
A method for endoluminally excluding an aortic aneurysm in a patient's vascular system, comprising the steps of: advancing through each branch of the patient's femoral and iliac system a respective graftstcnt complex, each graftstent complex comprising a first stent, a second stent and a graft connected between said first and second stents, said second stent being a self-expanding stent; positioning said first stents relative to each other in a common region of normal aortic tissue on one side of the aneurysm; deploying each of said positioned first stents in the common region; and deploying each of said second stents in the iliac arteries.
Claim 9
Dependent Claim
17 words
The method as in claim 5 , wherein each graftstent complex is advanced within a delivery catheter.
Claim 10
Dependent Claim
14 words
The method as in claim 6 , wherein said delivery catheter includes a guidesheath.
Claim 11
Dependent Claim
19 words
The method as in claim 7 , including wherein said second stents are deployed upon retraction of the guidesheath.
Claim 12
Dependent Claim
33 words
The method as in claim 5 , wherein the step of deploying said second stents comprises maintaining the position of the second stents relative to the patient's vasculature while withdrawing the guidesheath proximally.
Claim 13
Independent Claim
117 words
A method for endoluminally excluding an aortic aneurysm in a patient's vascular system, comprising the steps of: advancing through each branch of the patient's femoral and iliac system a respective graftstent complex, each graftstent complex comprising a first stent, a second stent and a graft connected between said first and second stents, said first stent having at least one barb for securing the position of the first stent within the patient's vascular system; positioning said first stents relative to each other in a common region of normal aortic tissue on one side of the aneurysm; deploying each of said positioned first stents in the common region; and deploying each of said second stents in the iliac arteries.
Claim 14
Independent Claim
117 words
A method for endoluminally excluding an aortic aneurysm in a patient's vascular system, comprising the steps of: advancing through each branch of the patient's femoral and iliac system a respective graftstent complex, each graftstent complex comprising a first stent, a second stent and a graft connected between said first and second stents, said first stent having at least one barb for securing the position of the first stent within the patient's vascular system; positioning said first stents relative to each other in a common region of normal aortic tissue on one side of the aneurysm; deploying each of said positioned first stents in the common region; and deploying each of said second stents in the iliac arteries.
