摘要：
Provided is an intraluminal foreign object capturing tool with which it is possible to cause a capturing member for capturing a foreign object to expand to an appropriate diameter. The foreign object capturing tool 10, in order to capture a foreign object in a lumen, includes: a core wire 20； a capturing member 30 which is disposed movably outside the core wire 20, has a farthest tip-end which is movement-regulated at a predetermined position of the core wire 20, and expands in diameter by contracting axially； a tubular member 50 which is disposed outside the core wire 20 on a base end side of the capturing member 30, and which regulates movement of capturing member 30 on the base end side； and control members 60 which are disposed outside the core wire 20 and inside the capturing member 30, and which regulate the amount of axial contraction of the capturing member 30. As the tubular member 50 and the core wire 20 are moved relative to each other, the capturing member 30 contracts axially by a length regulated by the control member 60 and expands in diameter.
