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 coughing pressures.

摘要： Devices, methods, and systems are provided for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment. A video-assisted thoracoscopic device is inserted into a thoracic cavity of a patient and positioned at a fissure between a target lung compartment and an adjacent lung compartment. A collateral flow channel between the target lung compartment and the adjacent lung compartment is then identified using the video-assisted thoracoscopic device and an agent is injected into the collateral flow channel, thereby reducing the collateral flow channel.

摘要： The volume of a hyperinflated lung compartment is reduced by sealing a distal end of the catheter in an airway feeding the lung compartment. Air passes out of the lung compartment through a passage in the catheter while the patient exhales. A one-way flow element associated with the catheter prevents air from re-entering the lung compartment as the patient inhales. Over time, the pressure of regions surrounding the lung compartment cause it to collapse as the volume of air diminishes. Residual volume reduction effectively results in functional lung volume expansion. Optionally, the lung compartment may be sealed in order to permanently prevent air from re-entering the lung compartment. The invention further discloses a catheter with a transparent occlusion element at its tip that enables examination of the lung passageway through a viewing scope.

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： Methods and systems for targeting, accessing and diagnosing diseased lung compartments are disclosed. The method comprises introducing a diagnostic catheter with an occluding member at its distal end into a lung segment via an assisted ventilation device; inflating the occluding member to isolate the lung segment; and performing a diagnostic procedure with the catheter while the patient is ventilated. The proximal end of the diagnostic catheter is configured to be attached to a console. The method may also comprise introducing the diagnostic catheter into the lung segment; inflating the occluding member to isolate the lung segment; and monitoring blood oxygen saturation. The method may further comprise introducing the diagnostic catheter into the lung segment; determining tidal flow volume in the lung segment; determining total lung capacity of the patient; and determining a flow rank value based on the tidal flow volume of the lung segment and the total lung capacity.

摘要： Methods, systems and devices are provided for performing lung volume reduction in patients suffering from chronic obstructive pulmonary disease or other conditions where isolation of a lung segment or reduction of lung volume is desired. The methods are minimally invasive with instruments being introduced through the mouth (endotracheally) and rely on isolating the target lung tissue segment from other regions of the lung and occluding various lung passageways with the use of occlusal stents. The occlusal stents are delivered with the use of an occlusal stent delivery system which is loaded with the occlusal stent with the use of an occlusal stent loading system.
