    摘要： Disclosed is an assembly for loading a bronchial flow control device into a container, such as into a delivery catheter. The assembly includes a funnel housing and a puller housing that mate with one another. The funnel housing defines a funnel-shaped loading cavity that receives a flow control device and that gradually reduces in size moving in a first direction. The puller housing is removably attached to the funnel housing and is also removably attachable to a bronchial flow control device that can be positioned in the loading cavity. The puller housing pulls the bronchial flow control device in the first direction through the funnel housing to gradually contract the bronchial flow control device into a compressed state of reduced size relative to the expanded state.

    摘要： An obturator for a bronchial tube or tubule of a human or animal lung comprises a blocking element (92) and a securing element (90). The blocking element serves to seal the tube or tubule against the passage of fluid past the obturator when the obturator is disposed in a bronchial tube or tubule. The securing element serves to retain the blocking element in position. The blocking element comprises a substantially cylindrical plug of biocompatible, resiliently deformable closed-cell foamed plastics material, such as PVC. The securing element comprises a stent having barbs (98) to engage and retain the blocking element. The stent also has anchors (100) to retain the stent in a bronchial tube or tubule. A method of treatment of emphysema or other lung conditions or diseases in human or animal patients comprises placing an obturator in a bronchial tube or tubule of the patient so as to seal the tube or tubule against the passage of fluid past the obturator.

    摘要： Methods and systems for determining collateral ventilation are disclosed. Methods may comprise introducing a diagnostic catheter into a lung compartment via an assisted ventilation device, inflating the occluding member to isolate the lung compartment, and performing a diagnostic procedure with the catheter while the patient is ventilated via the assisted ventilation device. The diagnostic procedure comprises determining an exhaled volume from the isolated lung compartment over a predetermined period of time while the patient is ventilated via the assisted ventilation device. The presence collateral ventilation may be determined based on the exhaled volume from the isolated lung compartment over the predetermined period of time.

    摘要： A method of diagnosing an air leak in a lung compartment of a patient may include: advancing a diagnostic catheter into an airway leading to the lung compartment; inflating an occluding member on the catheter to form a seal with a wall of the airway and thus isolate the lung compartment; measuring air pressure within the lung compartment during multiple breaths, using the diagnostic catheter; displaying the measured air pressure as an air pressure value on a console coupled with the diagnostic catheter; and determining whether an air leak is present in the lung compartment based on the displayed air pressure value during the multiple breaths.
