摘要： Methods and systems for targeting, accessing and diagnosing diseased lung compartments are disclosed. The method comprises introducing a diagnostic catheter with an occluding member at its distal end into a lung segment via an assisted ventilation device; inflating the occluding member to isolate the lung segment; and performing a diagnostic procedure with the catheter while the patient is ventilated. The proximal end of the diagnostic catheter is configured to be attached to a console. The method may also comprise introducing the diagnostic catheter into the lung segment; inflating the occluding member to isolate the lung segment; and monitoring blood oxygen saturation. The method may further comprise introducing the diagnostic catheter into the lung segment; determining tidal flow volume in the lung segment; determining total lung capacity of the patient; and determining a flow rank value based on the tidal flow volume of the lung segment and the total lung capacity.

摘要： A method for assessing lung function in a patient is disclosed. The method comprises isolating a lung compartment. Thereafter, in one embodiment, an inhaled gas of known composition is introduced into the lung and compared to the composition of the exhaled gas. Alternatively, accumulated CO2 content is measured within the isolated lung compartment over time, and compared to a baseline CO2 content. Alternatively, a change in pressure of an isolated lung compartment may be monitored. Alternatively, the magnitude of the range of CO2 values in an isolated lung compartment can be compared to a predetermined threshold. Any of the results obtained via these alternative embodiments may be used to determine lung function.

摘要： A method of determining potential treatment sites in a diseased lung is disclosed, in which an assessment catheter is introduced into a lung passageway. The catheter has a distal portion comprising an occluding member and a proximal portion configured to operatively mate with an external console. The catheter is used to identify one or more assessment sites within the airways of the lung. At each assessment site, at least one physiological, anatomical or biological characteristic is determined. A characteristic score for each assessment site is calculated based on a predetermined algorithm; and a treatment is determined based on the scores of the assessment sites. The algorithm takes into account several parameters including the disease characteristics as well as the number and proximity of each assessment site to at least one of the diseased regions. The method envisages treatment of emphysema, asthma or bronchopleural leak.
