摘要

Provided are a tubular treatment tool, a tubular treatment tool set, and a tubular treatment tool indwelling device that can be appropriately placed in a branched portion of a tubular tissue. The tubular treatment tool (stent graft 30) includes a skeletal portion (32) having a plurality of skeletal pieces (321 to 325) and a tubular graft portion (33) provided along the skeletal portion, and the graft portion. A side opening (through hole 36 of the branch 35) communicating with the lumen of the graft portion is provided on the tube wall of the graft portion, and the region from one end to the other end of the graft portion includes the side opening. When divided into the first region (P) and the second region (Q) not including the side opening, the skeleton pieces are not arranged in the first region but are arranged in the second region.
