PROBLEM TO BE SOLVED: To provide base cloth for a stent graft combining thinness, high strength, low water permeability and flexibility, and the stent graft insertable in a thinner catheter.SOLUTION: The base cloth for the stent graft is a woven fabric containing fiber with a cross section of fiber in an outermost surface layer being shaped to have a side roughly parallel with the outermost surface at least on one surface, and a woven fabric pressed by a calender or formed by arranging the major axis side of cross section of flat fiber perpendicularly to the thickness direction of the woven fabric. The woven fabric has a weave density of 150-400 strands/2.54 cm in both the vertical direction and the horizontal direction, and a thickness of 1-90 &mum.COPYRIGHT: (C)2012,JPO&INPIT【課題】薄さと高強力、低透水性、柔軟性を両立するステントグラフト用基布、及び、より細いカテーテルに挿入可能なステントグラフトを提供する。【解決手段】ステントグラフト用基布として、少なくとも一方の面にて、その最表面層の繊維の断面が最表面に略平行の辺を持つ形状である繊維を含む織物であり、カレンダーによるプレス処理が施された、または扁平繊維の断面の長軸側が織物の厚み方向と垂直に並べられた織物であり、織物の織密度がタテヨコ共に150~400本/2.54cm、厚みが1~90μm、とする。【選択図】図1
