1 Improvement in conformability of the latest generation of thoracic stent grafts 
Ludovic Canaud, MD, PhD, Philipe Cathala, MD, Frédéric Joyeux, MD, Pascal Branchereau, MD, Charles Marty-Ané, MD, PhD, Pierre Alric, MD, PhD  Journal of Vascular Surgery  Volume 57, Issue 4, Pages (April 2013) DOI: /j.jvs Copyright © 2013 Society for Vascular Surgery Terms and Conditions

2 Fig 1 Computed tomographic scan demonstrating poor apposition of the stent graft along the inner curve of the aortic arch, with the stent graft protruding into the lumen of the aorta.

3 Fig 2 Configurations of the proximal anchoring segments of the stent grafts tested. The Valiant (1), the C-TAG (2), and the Relay (4) have open bare springs; the Zenith (3) has hooks and barbs embedded in the covered graft material. Additionally, in the Relay graft (4), a curved nitinol wire (torsion bar) is sutured to the outer curve of the stent graft fabric to provide longitudinal support for optimal anatomic orientation.

4 Fig 3 The benchtop pulsatile flow model simulated an aortic isthmus whose angulations were variable according to the position of the distal connector in the rail. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2013 Society for Vascular Surgery Terms and Conditions

5 Fig 4 Intraluminal views of the proximal anchorage sites of the different stent grafts at 140° neck angulation: Cook with Pro-Form (1), C-TAG (2), Relay with Plus delivery system (3), and Valiant Captivia (4).
