A stent arrangement ( 12 ) and a stent graft ( 2 ) for curved lumens of the body. The stent graft has a tubular body ( 4 ) of a graft material, at least a portion of which may be arcuate to define an inner curved side ( 4 b) and an outer curved side ( 4 a) at least when deployed into the curved vessel. The stent graft has a plurality of self expanding stents ( 10, 12, 13 ) affixed thereto with a greater distance ( 11 a) between the stents on the outer curved side than on the inner curved side. The stents can be normal, tapered on one or both ends or skewed. When mounted onto a deployment device a twist ( 152, 154 ) may be provided in the graft material between adjacent stents to nest the stents. |
