    摘要： Disclosed is a method for treatment of emphysema by which it is possible to reduce the volume of pulmonary alveoli or alveolar sacs abnormally enlarged with destruction by emphysema. The method for treatment of emphysema includes: (a) inserting a catheter having a balloon into a bronchus or bronchiole; (b) dilating the balloon to occlude the bronchus or bronchiole; (c) shrinking pulmonary alveoli or alveolar sacs on the downstream side of the bronchus or bronchiole occluded in the step (b); and (d) injecting a hardening agent through the catheter into the respiratory region and hardening the hardening agent.

    摘要： A hollow fiber membrane oxygenator of external blood circulation type has a housing and a lot of porous hollow fiber membranes for gas transfer housed in the housing. In the oxygenator, blood flows along the outer side of the hollow fiber membranes, whereas oxygen-containing gas flows along the inner side thereof. An outer surface or outer layer of the hollow fiber membrane as a blood-contacting portion is coated with synthetic polymer mainly formed of alkoxyalkyl(meta)acrylate containing a C(1-4)alkoxy group and a C(1-4)alkyl group. An intermediate layer and inner layer of the hollow fiber membranes contain substantially no synthetic polymer.

    摘要： 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.
