Abstract

Disclosed is an apparatus for deploying a bronchial isolation device in a bronchial passageway in a lung of a patient. In one embodiment, the apparatus includes an outer shaft having a distal end. A housing is coupled to the distal end of the outer shaft and configured to receive the bronchial device. An inner shaft is slidably disposed within the outer shaft. A handle is adapted to move the outer shaft relative to both the inner shaft and the handle while the inner shaft remains fixed relative to the handle so as to eject the bronchial isolation device from the housing.
