Abstract:
1. A stent graft comprising: a tubular body of a biocompatible graft material, the tubular body having a circumference, a tubular body surface, an ostium in the tubular body surface, and a side arm extending from the ostium in the tubular body surface, and extending at least partially helically around and at least partially along the tubular body of the stent graft at least one-fourth the circumference of the tubular body to an open end of the side arm, the stent graft further including a temporary tie down arrangement for the side arm, the temporary tie down arrangement comprising at least one elongate longitudinally extending wire extending proximally of the open end of the side arm to distally of the open end of the side arm, the at least one elongate wire passing through the tubular body surface at a location distal to the open end of the side arm, through the graft material of the side arm, and then through the tubular body surface at a location proximal to the open end of the side arm to hold the open end of the side arm against the tubular body surface by the tie down wire between distal and proximal locations, wherein the open end of the side arm is retained in its position with respect to the tubular body during loading of the stent graft into a deployment device, wherein the stent graft further includes a second temporary tie down arrangement for the side arm, the second temporary tie down arrangement comprising at least one elongate longitudinally extending wire extending proximally of the ostium end of the side arm to distally of the ostium of the side arm and holding flat the ostium end of the side arm during loading of the stent graft into a deployment device.
