摘要：
An air passageway obstruction device (80,130,160) includes a frame structure (86,132,134,162,164,166) and a flexible membrane (112,150,186) overlying the frame structure. The frame structure (86,132,134,162,164,166) is collapsible upon advancement of the device into the air passageway, expandable into a rigid structure upon deploying in the air passageway and recollapsible upon removal from the air passageway. The flexible membrane (112,150,186) obstructs inhaled air flow into a lung portion communicating with the air passageway. The device (80,130,160) may be removed after deployment in an air passageway by recollapsing the device and pulling the device proximally through a catheter (70).
