In the treatment method, lung volume is reduced by restraining expansion and contraction of lung parenchyma present in the vicinity of a verge of a lung having an emphysema-suffering part, at least in one site of the verge.

Lung volume reduction method

A fibrosis-causing agent is highly effective in the fibrosis of tissues. The fibrosis-causing agent contains a fibrosis inducer and a fibrosis promoter. A fibrosis-causing agent dosage form and a method of administering the fibrosis-causing agent is also disclosed.

Fibrosis-causing agent

An object of the present invention is to provide an operating member with which curving operation of a catheter distal part can be easily carried out without moving a comparatively-large member. An operating member has a rotational operation part () that is fixed to an elongated body () for medical use and rotates the elongated body for medical use about the axis, pull wires () fixed to the elongated body for medical use, and a pull operation part () that is connected to the pull wires and curves at least part of the elongated body for medical use in a direction intersecting the axial direction by pulling the pull wire. The operating member further has a support part () that is provided rotatably about the axis of the elongated body for medical use and supports the pull operation part in such a state that the pull action of the pull operation part is possible, joining parts () that join the rotational operation part to the support part and rotate the support part and the pull operation part about the axis of the elongated body for medical use in association with the rotation of the rotational operation part, and a grip part () that is restricted in movement in the axial direction by being disposed between the rotational operation part and the support part and is provided pivotally independently of the rotational operation part and the support part.
