IMPROVED ENDOGRAFTS FOR ENDOVASCULAR REPAIR OF ABDOMINAL AORTIC ANEURYSMS

摘要

In one aspect, an endograft for the endovascular repair of an abdominal aorta having an aortic aneurysm and an aortic neck may generally include a moderately supported graft body extending lengthwise between a proximal end and a distal end. The graft body may include a proximal tube portion and first and second distal limbs. The proximal tube portion may extend lengthwise between the proximal end of the graft body and the first and second distal limbs. The first and second distal limbs may extend lengthwise between the proximal tube portion and the distal end of the graft body. The proximal tube portion may include a stented section having a stent configured to provide structural support to the proximal tube portion. In addition, each of the first and second distal limbs may correspond to non-stented portions of the graft body.
