Collateral flow channel sealant delivery methods and systems
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.
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.
2. The method of claim 1 , further comprising placing a clip on the collateral channel thereby pinching closed the collateral channel.
3. The method of claim 2 , wherein the clip is a normally closed clip.
4. The method of claim 1 , further comprising cutting tissue at the collateral flow channel thereby disrupting the collateral flow channel.
5. The method of claim 1 , wherein the collateral flow channel is sealed.
6. The method of claim 1 , wherein the agent is a sealant.
7. The method of claim 1 , wherein the agent is a sclerosing agent.
8. The method of claim 1 , wherein the agent is autologous blood.
9. A method as in claim 1 , further comprising:
accessing the target lung compartment using an endobronchial isolation catheter;
isolating the target lung compartment using the endobronchial isolation catheter;
measuring pressure or flow within the target lung compartment; and
verifying the collateral flow channel has been sealed based on the measured pressure or flow.
10. A method as in claim 1 , further comprising placing an endobronchial valve within an airway leading to the target lung compartment.
11. A method as in claim 10 , wherein the endobronchial valve is a one-way flow control valve configured to allow air to flow out of the target lung compartment and prevent air flow into the target lung compartment.
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.
13. 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;
cutting tissue at the collateral flow channel from the thoracic cavity thereby disrupting the collateral flow channel.
