1. 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.

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.

5. 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. - View Dependent Claims (6, 7, 8, 9)

10. 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.
