An implantable endograft device having a graded compliance. The endograft contains at least two portions having different compliance values. In some configurations, the endograft has three, a proximal end portion, a distal end portion, and a central portion, with the proximal and distal end portions having a higher compliance than the central portion. The difference in compliance can be achieved, for example, by using wire struts of different gauges, varying the spacing of the struts in the different portions, varying the geometry of the struts, using struts of different alloys, or using struts of differing elasticity.
