Abstract: 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.

Abstract: 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.

Abstract: Provided is an intravascular placement tool and an intravascular placement system that, when connecting and using multiple intravascular placement tools, enable smooth transport of an intravascular placement tool that is placed later. An intravascular placement tool (stent graft 1) is placed in a first blood vessel (main blood vessel V1) where a second blood vessel (branched blood vessel V2) branches. The intravascular placement tool (1) includes: a tubular placement tool body (graft body 10); and a branching portion (20) that is protrudingly provided on the placement tool body (10) and that can be connected with another intravascular placement tool (second stent graft 2) placed in the second blood vessel (V2). The relative arrangement between the placement tool body (10) and the branching portion (20) is defined on the basis of the relative positional relationship between the first blood vessel (V1) and the second blood vessel (V2).

Abstract: A tubular implanted appliance (103) is provided with a framework part (2) and a tubular coating film part (1) forming a partition wall, the tubular implanted appliance (10 3) being configured so as to be able to expand and retract in the axial direction of the coating film part. The framework part has a plurality of annular linear members (21) extending along the circumferential direction of the coating film part while bending in the axial direction of the coating film part. The plurality of linear members are disposed in a row in the axial direction of the coating film part, and are attached and fixed to the surface of the coating film part at intermediate portions (21c) between end parts in the axial direction of the linear members.
