1. A kit of parts for a modular stent graft assembly for repairing a ruptured or symptomatic aneurysm in an aortic artery, said kit of parts comprising:

  • a set of aortic sections each having a proximal end portion with a second diameter different from the second diameter of any other proximal end portion of the aortic sections in the set and greater than a first constant diameter of a distal end portion, each aortic section including a first tubular graft having a proximal end portion and a distal end portion, said distal end portion having a first constant diameter for a first predetermined length, said proximal end portion having a second diameter greater than said first constant diameter and sized for leakproof engagement within an aortic artery, said aortic section also having a first plurality of stents attached along said first tubular graft;

    a set of iliac sections each having a distal end portion with a third diameter different from the third diameter of any other distal end portion of the iliac sections in the set and at least equal to a fourth constant diameter of a proximal end portion, each iliac section including a second tubular graft including a distal end portion having a third diameter sized for leakproof engagement against an iliac artery, said second tubular graft also including a proximal end portion having a fourth constant diameter for a second predetermined length and approximating said first constant diameter of said distal end portion of said aortic section, said iliac section also having a second plurality of stents attached along said second tubular graft, whereby when said aortic and iliac sections are selected and positioned in an aortic artery and iliac artery, respectively, said proximal end portion of said iliac section and said distal end portion of said aortic section overlap at least a minimum length and engage each other when positioned one within another for said at least minimum length, andan occluder for the other iliac artery whereby the flow of blood to both iliac arteries can be maintained by a bypass graft between the two iliac arteries.
