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.
Claims11
A system for occluding a collateral flow channel and treating emphysema, the system comprising:
- a video-assisted thoracoscopic surgical device that is configured to be inserted into a thoracic cavity of a patient to identify a collateral flow channel between a target lung compartment and an adjacent lung compartment;
- a closure device that is configured to be inserted into the thoracic cavity of the patient to close the collateral flow channel between the target lung compartment and the adjacent lung compartment and thereby disrupt the collateral flow channel, wherein the thoracic closure device comprises a stapling device;
- and
- an endobronchial valve that is implantable in an airway leading to the target lung compartment to treat emphysema.
A system for occluding a collateral flow channel and treating emphysema, the system comprising:
- a stapling device that is configured to be inserted into a thoracic cavity of a patient via a video-assisted thoracoscopic surgical device to close a collateral flow channel between a target lung compartment and an adjacent lung compartment from the thoracic cavity and thereby disrupt the collateral flow channel;
- and
- an endobronchial valve that is implantable in an airway leading to the target lung compartment to treat emphysema.
