Abstract

Methods and devices for obstructing and aspirating lung tissue segments minimally invasive with instruments being intriduced through the mouth and rely on isolating the target lung tissue segments from other regions of the lung. Isolation is achieved by deploying an obstructive device (150) in a lung passageway (152) leading to the target lung tissue segment. Once the obstructive device is anchored in place, the segment can be aspirated through the device. This may be achieved by a number of methods, including coupling an aspiration catheter (10) to an inlet port on the obstruction device and aspirating through the port. Or, providing the port with a valve which allows outflow of gas from the isolated lung tissue segment during expiration of the respiratory cycle but prevents inflow of air during inspiration. The obstructive device may remain as an implant, to maintain isolation and optionally allow subsequent aspiration, or the device may be removed at any time.
