A medical blocking tool includes a core section and a swelling section provided around the core section. The core section reinforces the swelling section. The swelling section is formed of a swelling material which swells (expands) by absorbing a liquid so that the volume of the swelling section increases. The swelling section is adapted to swell until a bronchial tube is blocked while coming into close contact with the inner wall of the bronchial tube at a portion to be blocked (a blocking target portion) in the bronchial tube. |
