Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
88 words
1 . 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
Dependent Claim
88 words
1 . 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
37 words
2 . 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
24 words
3 . 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
25 words
4 . 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
33 words
5 . 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
26 words
6 . 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
22 words
7 . The method of claim 1 , further comprising the step of: expanding an expandable member to occlude a pulmonary location.
Claim 9
Dependent Claim
29 words
8 . 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
Dependent Claim
99 words
9 . 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
Dependent Claim
99 words
9 . 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
33 words
10 . 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
26 words
11 . 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
22 words
12 . The method of claim 9 , further comprising the step of: expanding an expandable member to occlude a pulmonary location.
Claim 15
Dependent Claim
29 words
13 . 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.
