  • Publication number: 20230136081
    Abstract: 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.

  • Publication number: 20230000387
    Abstract: 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.

  • Publication number: 20230000497
    Abstract: 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.
