Patent number: 12310594Abstract: 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.Type: GrantFiled: June 8, 2023Date of Patent: May 27, 2025Assignee: Pulmonx CorporationInventors: Sri Radhakrishnan, Ryan Olivera

Publication number: 20240156584Abstract: 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.Type: ApplicationFiled: November 16, 2023Publication date: May 16, 2024Applicant: Pulmonx CorporationInventors: Sri Radhakrishnan, Ryan Olivera
