  • Patent number: 12310594
    Abstract: 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.

  • Publication number: 20240366169
    Abstract: Devices, methods, and systems are provided for analyzing lung imaging data. A server computing device receives imaging data of a lung over a network from a client computing device and analyzes the imaging data to identify lung, airways, and blood vessels, segment the lung into lobes, subtract airways, calculate volumes, calculate emphysema scores, identify fissure locations, calculate fissure completeness scores. A reconstruction of the fissures indicating locations where the fissures are incomplete and a report comprising fissure scores, volumes, and emphysema scores are created.

  • Publication number: 20240156584
    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: 20220007962
    Abstract: Methods and systems for accessing and diagnosing diseased lung compartments are disclosed. Methods may comprise introducing a diagnostic catheter with an occluding member at its distal end into a lung segment; inflating the occluding member to isolate the lung compartment; and performing a diagnostic procedure with the catheter. The proximal end of the diagnostic catheter is configured to be attached to a console. Methods may also include allowing air to enter the lung compartment through the passage in the catheter while the patient is inhaling and blocking air from being expelled from the lung compartment through the catheter passage while the patient is exhaling by using a one-way flow element adapted to be disposed within or in-line with the passage of the catheter so that flow in a proximal-to-distal direction is allowed and flow in a distal-to-proximal direction is inhibited or prevented.
