Collateral flow channel sealant delivery methods and systems
First Claim
1. 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;
positioning the video-assisted thoracoscopic device at a fissure between a target lung compartment and an adjacent lung compartment;
identifying a collateral flow channel between the target lung compartment and the adjacent lung compartment using the video-assisted thoracoscopic device;
inserting a needle into the thoracic cavity and through tissue forming the collateral flow channel; and
injecting an agent through the needle and into the collateral flow channel, thereby reducing the collateral flow channel.

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.

12. 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; positioning the video-assisted thoracoscopic device at a fissure between a target lung compartment and an adjacent lung compartment; identifying a collateral flow channel between the target lung compartment and the adjacent lung compartment using the video-assisted thoracoscopic device; placing a clip into the thoracic cavity and on the collateral channel thereby pinching closed the collateral channel.
