#$%^&*AU2011202120B120120913.pdf#####ABSTRACT A stent graft defining a main lumen bounded by a wall of biocompatible graft material is disclosed. The stent graft has a valve portion between proximal and distal portions. The valve portion is formed 5 by a wall portion having a part-circumferential double layer portion comprising an inner underlap portion and an outer overlap portion, the double layer portion forming a passageway parallel to the main lumen. The passageway has an entrance mouth and an exit mouth, the exit mouth closer to a proximal end of the stent graft than the entrance mouth. The passageway has a closed condition where the underlap and overlap portions are in contact and an open condition where the underlap and overlap [0 portions are spaced apart to form a vent lumen. The wall portion is broken by a narrow cut or slot, the cut having a first edge and a second edge. The cut is openable by relative radial movement of the first edge away from the second edge. This allows re-perfusion of an aneurism and perfusion of blood from within the lumen out towards blood vessels such as intercostals and hence can assist in minimising the chance of paraplegia.
