Claims14
An endovascular stent graft conversion device, comprising:
- a graft segment comprising a first end and a second end, wherein the first end is adapted for engaging a limb of an endograft device, wherein the second end comprises three or more graft branches extending therefrom, wherein the three or more graft branches all extend from the second end at the same location.
A graft system, comprising:
- an endovascular stent graft, wherein the endovascular stent graft comprises one or more limb;
- and
- a conversion device, the conversion device comprising a graft segment comprising a first end and a second end, wherein the first end is adapted for engaging one of the limbs of the endovascular stent graft, wherein the second end comprises three or more graft branches extending therefrom.
A method for thoraco-abdominal aortic aneurysm repair in a subject, comprising:
- providing a bifurcated endovascular stent graft, wherein the endovascular stent graft comprises a contralateral limb;
- deploying the endovascular stent graft within the aorta of the subject;
- providing a conversion device, the conversion device comprising a graft segment comprising a first end and a second end, wherein the first end is adapted for engaging the contralateral limb of the endovascular stent graft, wherein the second end comprises three or more graft branches extending therefrom;
- deploying the conversion device within the aorta of the subject;
- and
- engaging the contralateral limb of the endovascular stent graft with the first end of the conversion device.
