1 Evaluation of a modular endovascular bifurcation prosthesis in a canine aortic aneurysm model 
Rodney A. White, MD, Thomas J. Fogarty, MD, George E. Kopchok, BS, Eric Wilson, MD, Bruce Ayres, MD, Marek Zalewski, MD, Carlos E. Donayre, MD  Journal of Vascular Surgery  Volume 24, Issue 6, Pages (December 1996) DOI: /S (96) Copyright © 1996 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions

2 Fig. 1 Component endovascular prosthesis composed of bifurcated body with integral iliac leg and separately inserted contralateral iliac component.

3 Fig. 2 Intravascular ultrasonography images of flow divider in bifurcated prostheses before (A) and after redesign of suprastructure (B) to ensure concentric positioning of iliac limbs without impingement or compression of one limb on the other. IVUS catheters (u) are positioned near flow divider within right iliac limb (single arrows) and obtain images of configuration of contralateral iliac limb (double arrows) across flow divider (f).
