摘要： The present invention eliminates the need for highly accurate alignment with a branched tubular tissue when implanting a stent graft. A stent graft 30 comprises: a framework section 31; and a tubular graft section 40. A side surface opening 42 that passes through to the lumen of the graft section is provided in one section of a tube wall 41 of the graft section. In the framework section, among the six frame bodies, the frame bodies 34, 35 that are provided facing the side surface opening section have a first frame body structure section Q that is present in the tube wall along the entire circumference, and a second frame body structure section P that is present in the tube wall in a partial region 41A, which excludes the side surface opening section in the circumferential direction of the tube wall.

摘要： Provided are a tubular therapeutic implement, a tubular therapeutic implement set, and a tubular therapeutic implement indwelling device, all of which enable appropriate indwelling at a branching portion in a tubular tissue. This stent graft 30 is provided with: a frame portion (32) having a plurality of frame pieces (321-325); and a tubular graft portion (33) which is provided along the frame portion, wherein the tube wall of the graft portion is provided with a lateral opening (through-hole 36 of a branching section 35) that is connected with an inner cavity of the graft portion, and when the region between one end and the other end of the graft portion is compartmented into a first region (P) that includes the lateral opening and a second region (Q) that dose not include the lateral opening, the frame pieces are not situated in the first region, but are in the second region.
