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.
Claims18
A method for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment, said method comprising:
- inserting a video-assisted thoracoscopic device into a thoracic cavity of a patient;
- inserting a cutting device through an incision on the chest of the patient into the thoracic cavity;
- and
- cutting tissue at a collateral flow channel between a target lung compartment and an adjacent lung compartment using the cutting device from the thoracic cavity thereby disrupting the collateral flow channel.
A method for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment, said method comprising:
- inserting a video-assisted thoracoscopic device into a thoracic cavity of a patient;
- inserting a needle through an incision on the chest of the patient into the thoracic cavity and through tissue forming a collateral flow channel between a target lung compartment and an adjacent lung compartment;
- and
- injecting an agent through the needle and into the collateral flow channel, thereby reducing the collateral flow channel.
A method for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment, said method comprising:
- inserting a video-assisted thoracoscopic device into a thoracic cavity of a patient;
- inserting a closing device into the thoracic cavity of the patient;
- and
- clipping, stapling, or suturing tissue at a collateral flow channel between a target lung compartment and an adjacent lung compartment using the closing device from the thoracic cavity thereby disrupting the collateral flow channel.
