Figure 1. Computer-generated image illustrating a modular, two-piece bifurcated graft. The main component comprises a body and one limb, introduced from the left femoral artery in this case (curved arrows). There is a short limb in the main component on the sideopposite to that of introduction (straight arrow). An extension limb (open arrows) is docked with this short limb to complete the bifurcated device.
