Endovascular grafts and methods for extended aortic repair

An endovascular graft comprising:

• a stent graft including:
• an elongated body movable between a constrained configuration and an expanded configuration, the elongated body having a proximal end portion, a distal end portion, an intermediate portion extending between the proximal and distal end portions, and a lumen extending between the proximal and distal end portions, the elongated body further including a frame structure having a portion covered by a compression sleeve that retains the body in the constrained configuration until deployment of the stent graft is needed;
• a first cuff member attached to the elongated body and moveable between a constrained configuration and expanded configuration, the first cuff member having a lumen in fluid communication with the lumen of the elongated body, the first cuff member sized and dimensioned to extend into a lumen of an aortic arch branch vessel when the endovascular graft is implanted in a subject, the first cuff member having a compression sleeve disposed thereon that retains the first cuff member in the constrained configuration until deployment of the first cuff member is needed;
• wherein the elongated body includes an aperture in fluid communication with the lumen of the elongated body and the lumen of the first cuff member, the aperture being defined by a portion of the frame structure, the frame structure including a backstop sized and dimensioned to extend into the lumen of the first cuff member when the endovascular graft is implanted in the subject;
• and
• a surgical graft partially attached to the stent graft at the proximal end portion thereof, wherein a proximal end of the surgical graft includes a sewing cuff attached thereto.
