## Abstract

An endovascular graft including a stent graft and a surgical graft is provided. The stent graft can include an elongated body having a collapsed and expanded configuration and include a frame structure covered by a compression sleeve that retains the elongated body in the collapsed configuration until deployment of the stent graft. The endovascular graft can include a 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 frame structure can include a backstop sized and dimensioned to extend into the first cuff member when the endovascular graft is implanted in the subject. The surgical graft can be partially attached to the stent graft at a proximal end portion thereof.

## Claims

### Claim 1

A method for repairing a diseased aortic arch in a subject, the method comprising the steps of:
obtaining an endovascular graft comprising a stent graft that is partially attached to a surgical graft, the stent graft comprising an elongated body and a first cuff member, the stent graft 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, the first cuff member being attached to the elongated body so that a lumen of the first cuff member is in fluid communication with the lumen of the elongated body, the first cuff member having a compression sleeve disposed thereon, the elongated body including 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;
positioning the first cuff member, in a constrained configuration, in an aortic arch branch vessel of the subject;
positioning the stent graft, in a collapsed configuration, in the aortic arch of the subject;
actuating the compression sleeve of the first cuff member so that the first cuff members expands into the aortic branch vessel;
actuating the compression sleeve of the stent graft so that the stent graft expands into the distal aortic arch;
securing the stent graft in the distal aortic arch; and
securing the surgical graft to a transected edge of the aorta.

### Claim 2 (depends on 1)

The method of claim 1, wherein the aortic arch branch vessel is the left subclavian artery of the subject.
