Abstract: A stent graft having a tubular body with a ostium in the side wall of the tubular body and a side arm extending from the ostium. The side arm comprising a tube of graft material extending at least partially helically around and longitudinally along the tubular body of the stent graft at least one-fourth the circumference of the tubular body to an open end and has a resilient reinforcing ring attached about and encircling its open end. The resilient reinforcing ring is permanently attached to the tubular body with a tie down arrangement that passes through the graft material of the tubular body and through the side arm and engages the resilient reinforcing ring to permanently hold the open end of the side arm against the tubular body surface. A line of radiopaque markers extends along the length of the side arm from the ostium to the open end.

Abstract: An arrangement for temporarily retaining a side arm (36) of a stent graft (30) in a selected position during loading thereof onto a deployment device, the side arm extending from an ostium (38) in the tubular body (32) and substantially helically around and along the tubular body to an open end (40). A first tie down wire (48) is stitched through the tubular body and through the side arm and then through the biocompatible graft material of the tubular body at the open end of the side arm. The stent graft can then be loaded into a sheath of a deployment device for the stent graft. There can be a second tie down wire (50) stitched through the biocompatible graft material of the tubular body and through the side arm and then through the biocompatible graft material of the tubular body at the ostium end of the side arm. The first and/or second tie down wires can be withdrawn after the stent graft is loaded into the sheath or left in place until delivery.
