Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 86 words
A method of treating the lung, comprising the steps of: advancing a device through an intrapulmonary path to a blocking element, the blocking element being previously implanted in a patient's lung for isolating a portion of a patient's lung; performing a procedure with the device on the isolated portion of the patient's lung, the device extending through the previously implanted blocking element; and removing the device after the performing step, wherein the blocking element prevents airflow in the inhalation direction after the device has been removed.
Claim 2
Independent Claim 86 words
A method of treating the lung, comprising the steps of: advancing a device through an intrapulmonary path to a blocking element, the blocking element being previously implanted in a patient's lung for isolating a portion of a patient's lung; performing a procedure with the device on the isolated portion of the patient's lung, the device extending through the previously implanted blocking element; and removing the device after the performing step, wherein the blocking element prevents airflow in the inhalation direction after the device has been removed.
Claim 3
Dependent Claim 35 words
The method of claim 1 , wherein: the advancing, performing and removing steps are carried out with the blocking element preventing air flow in an inspiratory direction but permitting air flow in an expiratory direction.
Claim 4
Dependent Claim 22 words
The method of claim 1 , wherein: the performing step is carried out by applying suction through a lumen in the device.
Claim 5
Dependent Claim 23 words
The method of claim 3 , wherein: the performing step is carried out to remove air from the isolated portion of the lung.
Claim 6
Dependent Claim 31 words
The method of claim 1 , wherein: the performing step is carried out by delivering a therapeutic substance to the isolated portion of the lung through a lumen in the device.
Claim 7
Dependent Claim 24 words
The method of claim 5 , further comprising the step of: removing material from the isolated portion of the lung after the performing step.
Claim 8
Dependent Claim 20 words
The method of claim 1 , further comprising the step of: expanding an expandable member to occlude a pulmonary location.
Claim 9
Dependent Claim 27 words
The method of claim 1 , wherein: the advancing step is carried out with the blocking element sealing around the device when the device is positioned therein.
Claim 10
Independent Claim 97 words
A method of treating the lung, comprising the steps of: advancing a device through a bronchial passageway to a blocking element, the blocking element being previously implanted in the bronchial passageway to control fluid flow to and from an isolated portion of a patient's lung; performing a procedure with the device on the isolated portion of the patient's lung, the device extending through the previously implanted blocking element; and removing the device after performing the procedure, wherein the blocking element prevents air flow through the bronchial passageway in the inhalation direction after the device has been removed.
Claim 11
Independent Claim 97 words
A method of treating the lung, comprising the steps of: advancing a device through a bronchial passageway to a blocking element, the blocking element being previously implanted in the bronchial passageway to control fluid flow to and from an isolated portion of a patient's lung; performing a procedure with the device on the isolated portion of the patient's lung, the device extending through the previously implanted blocking element; and removing the device after performing the procedure, wherein the blocking element prevents air flow through the bronchial passageway in the inhalation direction after the device has been removed.
Claim 12
Dependent Claim 31 words
The method of claim 9 , wherein: the performing step is carried out by delivering a therapeutic substance to the isolated portion of the lung through a lumen in the device.
Claim 13
Dependent Claim 24 words
The method of claim 10 , further comprising the step of: removing material from the isolated portion of the lung after the performing step.
Claim 14
Dependent Claim 20 words
The method of claim 9 , further comprising the step of: expanding an expandable member to occlude a pulmonary location.
Claim 15
Dependent Claim 27 words
The method of claim 9 , wherein: the advancing step is carried out with the blocking element sealing around the device when the device is positioned therein.
