The system includes a filling structure deployable at least partially within the common iliac and external iliac arteries, and a scaffold located within the first lumen of the filling structure. The scaffold has a fenestration on its side that can be placed toward the internal iliac artery. The filling structure has a second lumen that extends from the first lumen and is positionable toward the internal iliac artery. The method includes deploying a filling structure at least partially within the common iliac and external iliac arteries, placing a scaffold within the lumen of the filling structure, and directing a fenestration on the side of the scaffold toward the internal iliac artery. And arranging. [Selection] Figure 4システムが、少なくとも部分的に総腸骨動脈及び外腸骨動脈内で展開可能な充填構造と、充填構造の第１のルーメン内に位置する足場とを含む。足場は、その側面に、内腸骨動脈に向けて配置可能な開窓を有する。充填構造は、第１のルーメンから延びて内腸骨動脈に向けて配置可能な第２のルーメンを有する。方法は、少なくとも部分的に総腸骨動脈及び外腸骨動脈内で充填構造を展開するステップと、充填構造のルーメン内に足場を配置し、足場の側面の開窓を内腸骨動脈に向けて配置するステップとを含む。【選択図】図４
