Abstract: A stent graft for placement in a lumen of a patient is disclosed. The stent graft comprises: a main tubular body of a biocompatible graft material having a main lumen, the main tubular body having a proximal end and a distal end; a side arm extending from the main tubular body, the side arm having a side arm lumen, the side arm lumen being in fluid communication with the main lumen through a side arm opening in the main tubular body; and a cannulation pocket. The pocket comprises: an exit aperture positioned opposite the side arm opening; an entry aperture longitudinally spaced from the entry aperture in a direction toward the distal end of the main tubular body; and a wall, the wall laterally spaced from the main lumen so as to provide a guide surface for a cannula fed through the entry aperture.

Abstract: A stent graft and delivery device assembly comprises a dilator 3, a stent graft receiving portion distal of the dilator, an elongate seal-engaging sleeve portion 185 distal of the stent graft receiving portion, a stent graft 35 mounted on the stent graft receiving portion, a stent graft cover 100 mounted around the stent graft, the cover having a maximum outer diameter, and an introducer 40 disposed around the elongate seal-engaging sleeve portion. The introducer has a hollow body, a haemostatic device 33 and an introducer catheter 45 extending from the hollow body. The inner diameter D of the catheter is greater than the outer diameter Y of the seal-engaging sleeve portion 185. The seal-engaging sleeve portion has a maximum outer diameter Y less than the maximum outer diameter C of the cover 100.

Abstract: A radially expandable stent graft 10 for placement in a lumen of a patient is disclosed. The stent graft 10 comprises: a prosthetic trunk 100 comprising a trunk lumen 110 there-through; a prosthetic branch 300 comprising a branch lumen 310 extending there-through, wherein the branch lumen 310 is in fluid communication with the trunk lumen 110 through a lateral opening 115 in the trunk lumen 110; a valve 150 comprising a fenestration 152 for providing temporary lateral access into the trunk lumen 110, the valve 150 positioned opposite the lateral opening 115 in the trunk lumen 110; and a valve actuator. The valve actuator closes the fenestration 152 as the stent graft 10 expands.
