AI Technical Summary
Technical Problem
The prior art is difficult to permanently block air passages in the lungs to achieve lung volume reduction without surgery, and there is a lack of effective equipment and methods for fixing and removing obstructions.
Method used
A one-way valve device is adopted, which includes a frame structure and frameless membrane component, by placing an obstruction in the air passage, preventing inhaled air from flowing into the portion to be folded in the lung, and fixing and removability of the obstruction through anchors and flexible membrane flaps.
Benefits of technology
It is achieved without surgery, permanently blocking air passages, improving lung function, and providing removable obstructions to suit different needs.

Abstract
The present invention is entitled "Removable Fixed Lung Volume Reduction Device". The present invention discloses a one-way valve device for blocking airflow in a pulmonary passage. The device includes a frame structure and a frameless membrane. The frame structure includes a hub and an anchor. The frameless membrane is attached to the hub segment. The anchor and the frameless membrane are located at a first radial position in a closed configuration and at a second radial position in an open configuration. The first radial position is closer to the central longitudinal axis of the device than the second radial position. The frameless membrane includes a plurality of flaps connected to a base segment. In the open configuration, the flaps are bent from the central longitudinal axis of the one-way valve device. When the one-way valve device is in an open or closed configuration, the proximal segment of the flap overlaps the proximal segment of an adjacent flap.
