Abstract
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 (4b) and an outer curved side (4a) 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 (11a) 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.
