A stent graft can be held in place on the outside of the thoracic arch by a hypodermic needle tube which passes through the bore of the stent graft and back to the user. A centre tube tethered to the stent graft at the end distal to the user is employed to hold the stent graft within the pulsatile blood flow, preventing the stent graft from collapsing during deployment. The position of both the hypodermic needle tube and the centre tube can be controlled by the user by means of a control handle.

Une endoprothèse vasculaire peut être maintenue en place sur l'extérieur de l'arc thoracique par un tube d'aiguille hypodermique qui passe à travers l'alésage de l'endoprothèse vasculaire et revient vers l'utilisateur. Un tube central relié à l'endoprothèse vasculaire à l'extrémité distale au patient est employé pour maintenir l'endoprothèse vasculaire dans l'écoulement sanguin pulsatile, empêchant l'endoprothèse vasculaire de s'effondrer au cours du déploiement. La position du tube d'aiguille hypodermique et du tube central peut être contrôlée par l'utilisateur au moyen d'une commande manuelle.
