Endovascular graft having a cannulation pocket

A stent graft assembly for placement in a lumen of a patient, the stent graft assembly comprising a stent graft and a pre-loaded guide wire, the stent graft comprising:

• 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 comprising:
• 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,
• the wall enclosing a pocket lumen, the pocket lumen outside of the main tubular body, the exit aperture disposed in the main tubular body and opening into the pocket lumen;
• wherein the pre-loaded guide wire comprises:
• a first wire end projecting from the distal end of the main tubular body;
• an intermediate wire portion extending through the entry aperture, the exit aperture and the side arm opening;
• and
• a second wire end projecting outwardly from the side arm.
