Bronchial flow control device

In order to attain desired fluid flow dynamic in a lung domain between breathing and/or to make atrophy induce in one or the lung domain beyond it, the method and equipment which adjust the fluid flow which frequents the domain of a patient's lung are indicated. The domain of the specified lung turns into a target domain which deals with improving the flow of the domain of the lung concerned, for example, or attaining capacity reduction or atrophy of the domain concerned etc. The above-mentioned target lung domain is divided in bronchus in order to adjust after that the flow of the air which frequents the domain concerned through one or the bronchus passage beyond it to which air is led. Bronchus division of this target domain is attained by flowing into the bronchus passage which leads air to the target domain concerned, and 移殖 (ing) a control device.
