Abstract
A lung volume reduction system includes a percutaneously, laparoscopically or thorocospically insertable delivery element comprising a control end which remains outside the body and an insertion end which, when in an operative position, is adjacent to an external surface of a target portion of a lung and a constriction element deployable from the distal end of the delivery element to apply compressive force to an external surface of the target portion of the lung to constrict at least one airway therein and collapse the target portion of the lung.

A lung volume reduction system, comprising:
- a percutaneously insertable delivery element comprising a control end which remains outside the body and an insertion end which, when in an operative position, is adjacent to an external surface of a target portion of a lung;
- and
- an elastic bag deployable from the distal end of the delivery element to apply compressive force to an external surface of the target portion of the lung to constrict at least one airway therein and collapse a portion of the target portion of the lung.
A method for treating a respiratory condition, comprising:
- inserting an insertion instrument into the thoracic cavity via an incision;
- passing an elastic bag through the insertion instrument and stretching an opening of the bag to position the bag over a target portion of the lung;
- and
- releasing the bag to applying a compressive force to an external surface of the target portion of the lung to constrict at least one airway therein and collapse a portion of the target portion of the lung.
