Abstract:
1. A method for treating a target lung compartment, said method comprising: inserting a catheter having a detachable flow restrictive component connected thereto into the target lung compartment; deploying the detachable flow restrictive component while remaining connected to the catheter in an airway feeding the target lung compartment, whereby the target lung compartment is isolated and a flow path is created between a lumen in the shaft and a passage, lumen, or open interior within the detachable flow restrictive component which permits gas exchange between the lumen in the shaft and a distal region of the detachable flow restrictive component; determining whether collateral ventilation exists in the target lung compartment while the detachable flow restrictive element remains deployed in the airway; and detaching the detachable flow restrictive component from the catheter to leave said component in place in the airway if no significant collateral ventilation present; and contracting the detachable flow restrictive component and removing the catheter together with the detachable flow restrictive component if significant collateral ventilation is determined to be present.
