The coiled stent is affixed to the graft material of the first portion.The first portion has a first portion diameter and the coiled stent has a helixdiameter which is substantially the same as the first portion diameter. The coiledstent comprises a ratio of helical pitch to helix diameter of from about 1 :2 toabout 1 :20, where the helical pitch is the spacing between adjacent turns of thecoiled stent.
