ENDOVASCULAR GRAFT HAVING A CANNULATION POCKET

摘要

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.
