Abstract
Abstract A bifurcated graft is formed from a series of individual components which are intraluminally delivered apart from one another and then assembled to form a fully supported structure. The modular system includes a base member and one or more grafts connected thereto. The base member preferably includes a portion which gradually increases in diameter. A tubular device for inserting the components of the modular system and a method employing the modular system for repairing an abdominal aortic aneurysm are also disclosed.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
115 words
A modular endovascular graft for repairing an aortic aneurysm, comprising: a body, the body having a superior end defining a single inlet and an inferior end, the superior end sized to fit an aorta of an adult human, and further including a stent attached to the body prior to the body being placed within vasculature; and an extender in the form of a graft, the extender configured to mate with the superior end of the body, the extender having a single inlet and a single outlet, wherein the extender is configured to be delivered into vasculature separately from the body and to be attached to the body after the body is placed in the vasculature.
Claim 2
Dependent Claim
115 words
A modular endovascular graft for repairing an aortic aneurysm, comprising: a body, the body having a superior end defining a single inlet and an inferior end, the superior end sized to fit an aorta of an adult human, and further including a stent attached to the body prior to the body being placed within vasculature; and an extender in the form of a graft, the extender configured to mate with the superior end of the body, the extender having a single inlet and a single outlet, wherein the extender is configured to be delivered into vasculature separately from the body and to be attached to the body after the body is placed in the vasculature.
