Stent graft, stent graft set, and stent graft indwelling device

摘要

PROBLEM TO BE SOLVED: To provide a stent graft being easily placed at an appropriate position.SOLUTION: A stent graft 10 is a tubular stent graft delimiting a flow passage in which a blood flow can pass. The stent graft 10 includes: a skeleton part 11 capable of contracting radially inward and expanding radially outward; and a membrane part 12 provided along the skeleton part 11. The stent graft 10 is deformable from a contracted state in which the skeleton part 11 is contracted, to the expansion state in which the skeleton part 11 is expanded and the flow passage is delimited by the membrane part 12. The membrane part 12 includes an opening part 13. In the expanded state, the opening part 13 has a recess area 14 where a part of a peripheral edge of the opening part is recessed in a direction of separating from a center P of the opening part, and has such an opening shape that an opening width L is gradually reduced with it approaching from the center P of the opening part toward a deepest part Q of the recess area 14.SELECTED DRAWING: Figure 2
