  • Lung reduction apparatus and method
    Publication number: 20020188171
    Abstract: An apparatus and method reduces the size of a lung. The apparatus includes a jacket of flexible fabric configured to cover at least a portion of the lung. A lace, carried by the jacket, collapses the jacket about the lung portion. The jacket may further include a drawstring circumscribing the jacket at the base for closing the open base of the jacket about the lung portion. The collapsing of the jacket may be employed for both reducing the size of the lung and maintaining the lung in a reduced size condition or the lung portion may be deflated prior to the placement of the jacket over the lung portion, in which case, the jacket serves to prevent re-expansion of the lung portion.

  • Lung reduction device, system, and method
    Patent number: 6293951
    Abstract: A device, system, and method provides for lung size reduction by permanently collapsing at least a portion of a lung. The lung portion may be collapsed by obstructing the air passageway which communicates the lung portion to be collapsed. The air passageway may be obstructed by an obstructing member which precludes airflow in either direction or with a one-way valve which permits air to be exhaled from the lung portion while precluding air from being inhaled into the lung portion. In addition, a vacuum may be pulled within the lung portion to be collapsed for collapsing the lung portion and while the lung portion is collapsed the obstructing member may be placed in the air passageway to maintain the lung portion in a permanently collapsed state.
