[0002] 1. Field of the Invention

[0003] The present invention relates generally to methods and devices for use in performing pulmonary procedures, and more particularly, procedures for treating various diseases of the lungs.

[0004] 2. Description of the Background Art

[0005] Pulmonary diseases such as emphysema and chronic obstructive pulmonary disease (COPD) reduce the ability of one or both lungs to fully expel air during the exhalation phase of the breathing cycle. The diseased lung tissue is less elastic than healthy lung tissue, which is one factor that prevent...
