Methods, systems and devices are described for new modes of ventilation in which specific lung areas are ventilated with an indwelling trans-tracheobronchial catheter for the purpose of improving ventilation and reducing hyperinflation in that specific lung area, and for redistributing inspired air to other healthier lung areas, for treating respiratory disorders such as COPD, ARDS, SARS, CF, and TB. Trans-Tracheobronchial Segmental Ventilation (TTSV) is performed on either a naturally breathing or a mechanical ventilated patient by placing a uniquely configured indwelling catheter into a bronchus of a poorly ventilated specific lung area and providing direct ventilation to that area. The catheter can be left in place for extended periods without clinician attendance or vigilance. Ventilation includes delivery of respiratory gases, therapeutic gases or agents and evacuation of stagnant gases, mixed gases or waste fluids. Typically the catheter's distal tip is anchored without occluding the bronchus but optionally may intermittently or continuously occlude the bronchus. TTSV is optionally performed by insufflation only of the area, or by application of vacuum to the area, can include elevating or reducing the pressure in the targeted area to facilitate stagnant gas removal, or can include blocking the area to divert inspired gas to better functioning areas.
A method for directly ventilating a compartment of a lung via a continuously indwelling catheter placed in the bronchial tree, wherein said catheter has a distal end and a proximal end, wherein said distal end is anchored in the bronchus of said lung compartment, and wherein said proximal end is connected to an ventilation source external to the patient, and wherein said catheter can remain in place for extended periods without clinician vigilance and wherein said ventilation source includes a gas removal means and a gas delivery means and wherein said ventilating includes gas delivery and gas removal.
A method for directly ventilating a compartment of a lung via a continuously indwelling catheter placed in the bronchial tree, wherein said catheter has a distal end and a proximal end, wherein said distal end is anchored in the bronchus of said lung compartment, and wherein said proximal end is connected to an ventilation source external to the patient, and wherein said catheter can remain in place for extended periods without vigilance.
A method for directly aspirating an area of a lung via a continuously indwelling catheter placed in the bronchial tree, wherein said catheter has a distal end and a proximal end, wherein said distal end is anchored in the bronchus of said lung area, and wherein said proximal end is connected to an vacuum source external to the patient, and wherein said catheter can remain in place for extended periods without vigilance.
A method as in claim 31 wherein said aspiration comprises a positive pressure venturi gas jet at the distal end of said catheter wherein said jet is directed in the proximal direction away from targeted said lung area.
A method for blocking airflow into a compartment of a lung with an occlusion means, said occlusion means comprising a continuously indwelling catheter with an occlusion member at said catheter's distal end, wherein the proximal end of said catheter remains external to the patient and wherein said catheter can remain in place for extended periods without vigilance.
A method as in claim 33 wherein said catheter includes a lumen and wherein a vacuum is delivered to said lung compartment via said lumen, wherein said vacuum is delivered continuously, intermittently or variably.
An apparatus and kit for the purpose of directly ventilating a lung area, comprising:
A system for site-specific ventilation of an area of a lung of a patient, comprising:
