Base fabric for stent graft, and stent graft

摘要

A base fabric for a stent graft is a woven fabric constituted by a fiber having a total fineness of 1 to 40 decitex and a single yarn fineness of 0.1 to 2.0 decitex and has a yarn density of 150 strands/2.54 cm or more in both longitudinal direction and lateral direction, a thickness of 1 to 90 μm, and a tensile strength of 50.0 N/cm or more in both longitudinal direction and lateral direction. According to the present invention, the base fabric for a stent graft having thinness, high strength, low permeability, durability, and flexibility can be obtained.
