A stent graft for deployment into the aorta of a patient has a tubular body with a proximal portion of a selected diameter; preferably a reduced diameter portion, distal of the proximal portion, having a diameter less than the selected diameter; a tapered portion, extending between the proximal portion and the reduced diameter portion; and optionally a distal portion, distal of the reduced diameter portion. At least three, preferably four or five, low profile side arms are provided, preferably in the reduced diameter portion and/or the tapered portion, for connection of an arm extension to an aortic branch vessel. All but one of the side arms are to be connected at the physician's choice, depending on the anatomy of the patient. One side arm is to provide temporary perfusion to external of the stent graft after deployment of the stent graft into the aorta, and is subsequently blocked.

A stent graft defining a main lumen bounded by a wall of graft material is disclosed. The stent graft has a valve portion between proximal and distal portions. The valve portion is formed 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 passageway has an open condition where the underlap and overlap portions are spaced apart to form a vent lumen. The wall portion is broken by a narrow cut. The cut is openable by relative radial movement between its edges. This allows re-perfusion of an aneurism and perfusion of blood from within the lumen out towards blood vessels such as intercostals and can assist in minimising the chance of paraplegia.

The invention relates to a central driving lower extremity exoskeleton robot. A motor in a back assembly is connected with an output shaft through a reducer and a gear group in a transmission manner. The output shaft is connected with spline assemblies which are on a left leg and a right leg through synchronous belt assemblies. The motor transmits force moment to hip joints through the reducer, gears, the output shaft, the synchronous belt assemblies, and the spline assemblies, so that the motor respectively providing assistant moment for the left leg and the right leg in a swinging period is realized. Compared with a multi-motor driving lower extremity assistance exoskeleton, the central driving lower extremity exoskeleton is lighter in weight, and saves more energy. An electromagnetic push rod is used as a transmission mechanism to control whether to transmit motor driving moment to hip joints or not, and a transmission structure is simpler, and control is more convenient. Two thigh assemblies are connected through a mooring rope, so as to drive the mooring rope to move using variation of a human body gravity center, playing certain assistance role. The robot can realize to provide assistance for the left leg and the right leg in a swinging period through a motor, and the robot provides assistance for sitting and standing of a paraplegia patient.
