    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.

    摘要： An obturator for a bronchial tube or tubule of a human or animal lung includes 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 includes 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： Devices for loading a collapsible implant onto a delivery catheter. In one aspect, a loading device comprises an outer tubular structure and an inner tubular structure. The outer tubular structure comprises a narrowing passage configured to receive a catheter at one end and a collapsible implant at another end. The inner tubular structure is configured to move slidably and co-axially within the outer tubular structure. The inner tubular structure comprises a carrier pin configured to move within the narrowing passage as the inner tubular structure slides into the outer tubular structure. The sliding of the inner tubular structure into the outer tubular structure causes an implant mounted on the carrier pin to collapse as the implant moves through the narrowing passage and into the distal end of a catheter. In an optional aspect, the outer tubular structure further comprises a grasper to stabilize the catheter for receipt of the collapsible implant, and the internal diameter of the inner tubular structure varies to cause the grasper to first contract and stabilize the catheter, and then expand and release the catheter, as the grasper moves into the inner tubular structure.

    摘要： A method for assessing lung function in a patient is disclosed. The method comprises isolating a lung compartment. Thereafter, in one embodiment, an inhaled gas of known composition is introduced into the lung and compared to the composition of the exhaled gas. Alternatively, accumulated CO2 content is measured within the isolated lung compartment over time, and compared to a baseline CO2 content. Alternatively, a change in pressure of an isolated lung compartment may be monitored. Alternatively, the magnitude of the range of CO2 values in an isolated lung compartment can be compared to a predetermined threshold. Any of the results obtained via these alternative embodiments may be used to determine lung function.

    摘要： Disclosed are methods and devices for regulating fluid flow to and from a region of a patient's lung, such as to achieve a desired fluid flow dynamic to a lung region during respiration and/or to induce collapse in one or more lung regions. Pursuant to an exemplary procedure, an identified region of the lung is targeted for treatment. The targeted lung region is then bronchially isolated to regulate airflow into and/or out of the targeted lung region through one or more bronchial passageways that feed air to the targeted lung region. An exemplary flow control device is configured to block fluid flow in the inspiratory direction and the expiratory direction at normal breathing pressures and allow fluid flow in the expiratory direction at higher than normal breathing pressures.
