Abstract
Abstract Systems, methods and devices for performing pulmonary procedures, and in particular treating lung disease. A flow control element includes a valve that prevents airflow in the inhalation direction but permits airflow in the exhalation direction. The flow control element is guided to and positioned at the site by a bronchoscope that is introduced into the patient's trachea and used to view the lungs during delivery of the flow control element. The valve may include one, two or more valve elements, and it may be collapsible for easier delivery. A source of vacuum or suction may be used to increase the amount of fluid withdrawn from the lung tissue. A device for measuring hollow structures, such as bronchioles, and a device for removing a previously-placed flow control element are disclosed as well.

Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
80 words
1 . A system for use in a lung of a patient comprising: a scope adapted for viewing a lung passageway in the lung, the scope having a shaft positionable in the patient's trachea and a working channel in the shaft; a delivery device movably positionable in the working channel; and a flow control element releasably coupled to the delivery device and adapted for implanting in the lung passageway to restrict fluid flow in at least an inspiration direction therethrough.
Claim 2
Dependent Claim
80 words
1 . A system for use in a lung of a patient comprising: a scope adapted for viewing a lung passageway in the lung, the scope having a shaft positionable in the patient's trachea and a working channel in the shaft; a delivery device movably positionable in the working channel; and a flow control element releasably coupled to the delivery device and adapted for implanting in the lung passageway to restrict fluid flow in at least an inspiration direction therethrough.
Claim 3
Dependent Claim
35 words
2 . The system of claim 1 , wherein the flow control element is movable between a collapsed configuration for positioning into the lung passageway and an expanded configuration for implanting in the lung passageway.
Claim 4
Dependent Claim
24 words
3 . The system of claim 2 , wherein the delivery device is adapted to hold the flow control element in the collapsed configuration.
Claim 5
Dependent Claim
46 words
4 . The system of claim 1 , wherein the delivery device comprises a support shaft configured for coupling to the flow control element and a sheath slidably disposed over the support shaft and configured to cover at least a portion of the flow control element.
Claim 6
Dependent Claim
25 words
5 . The system of claim 4 , further comprising an actuator associated with the delivery device for moving the sheath relative to the shaft.
Claim 7
Dependent Claim
25 words
6 . The system of claim 2 , wherein the flow control element comprises a stent movable between a collapsed configuration and an expanded configuration.
Claim 8
Dependent Claim
27 words
7 . The system of claim 6 , wherein the stent comprises a resilient material so as to self-expand from the collapsed configuration to the expanded configuration.
Claim 9
Dependent Claim
32 words
8 . The system of claim 1 , wherein the flow control element comprises a fixation structure thereon to aid in fixing the flow control element in place in the lung passageway.
