摘要：
Described is a method for deploying a stent-graft in the aorta, the method including positioning a shunt to go along a portion of a brain-supplying artery (BSA) into the aorta deploying a stent-graft in the aorta along a portion of the shunt and removing the shunt. Also described is a removable shunt adapted for deployment along a brain-supplying artery into an aorta to supply blood to the artery during deployment of a stent-graft in the aorta, the removable shunt including a stiff segment that is stiff enough to remain at least partially open when between the aorta and the stent-graft and large enough to allow sufficient blood supply to the brain during the deployment of the stent-graft and a mechanism for facilitating safe removal of the shunt from between the stent-graft and the aorta. Also described is a method of deploying a branch stent graft having a flaring portion in a blood vessel branching at a bifurcation from an aorta to connect to an aortic stent graft deployed in the aorta across the bifurcation, a branch stent-graft useful in the method, and a delivery system useful in the method.Linvention concerne un procédé pour déployer une endoprothèse couverte dans laorte, le procédé comprenant le positionnement dune dérivation pour aller le long dune partie dune artère alimentant le cerveau (BSA) à lintérieur de laorte le déploiement dune endoprothèse couverte dans laorte le long dune partie de la dérivation et le retrait de la dérivation. Linvention concerne également une dérivation amovible conçue pour un déploiement le long dune artère alimentant le cerveau à lintérieur dune aorte pour alimenter en sang lartère pendant le déploiement dune endoprothèse couverte dans laorte, la dérivation amovible comprenant un segment rigide suffisamment rigide pour rester au moins partiellement ouvert lorsquil se trouve entre laorte et lendoprothèse couverte et suffisamment large pour permettre une alimentation en sang suffisante vers le cerveau pendant le déploiement de le
