Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 57 words
1 . A system for delivering an element into the pulmonary system, comprising: a delivery element having a first lumen; and a pulmonary element releasably coupled to the delivery element, the pulmonary element and delivery element being configured for intrapulmonary delivery, the pulmonary element at least blocking air flow into an isolated portion of a patient's lung.
Claim 2
Dependent Claim 57 words
1 . A system for delivering an element into the pulmonary system, comprising: a delivery element having a first lumen; and a pulmonary element releasably coupled to the delivery element, the pulmonary element and delivery element being configured for intrapulmonary delivery, the pulmonary element at least blocking air flow into an isolated portion of a patient's lung.
Claim 3
Dependent Claim 19 words
2 . The system of claim 1 , further comprising: a source of vacuum coupled to the first lumen.
Claim 4
Dependent Claim 23 words
3 . The system of claim 1 , wherein: the delivery element has an expandable member mounted thereto for occluding a pulmonary passageway.
Claim 5
Dependent Claim 33 words
4 . The system of claim 1 , wherein: the delivery element has a second lumen, the expandable member being a balloon which is coupled to the second lumen for inflating the balloon.
Claim 6
Dependent Claim 29 words
5 . The system of claim 1 , wherein: the pulmonary element is a valve which permits air flow in one direction and blocks air in the other direction.
Claim 7
Dependent Claim 18 words
6 . The system of claim 1 , wherein: the pulmonary element is mounted within the first lumen.
Claim 8
Dependent Claim 30 words
7 . The system of claim 6 , wherein: the first lumen has an enlarged distal end, the pulmonary element being positioned in the enlarged portion of the first lumen.
Claim 9
Dependent Claim 19 words
8 . The system of claim 1 , further comprising: a source of fluid coupled to the first lumen.
Claim 10
Dependent Claim 29 words
9 . The system of claim 8 , wherein: the source of fluid contains a fluid selected from the group consisting of therapeutic agent, antibiotic, saline, sealant and adhesive.
Claim 11
Dependent Claim 54 words
10 . A system for delivering an element into the pulmonary system, comprising: a delivery element having a first lumen; and means for controlling fluid flow into an isolated portion of a patient's lung, the means for controlling dimensioned for insertion in the first lumen and also dimensioned for insertion into a bronchial passageway.
Claim 12
Dependent Claim 54 words
10 . A system for delivering an element into the pulmonary system, comprising: a delivery element having a first lumen; and means for controlling fluid flow into an isolated portion of a patient's lung, the means for controlling dimensioned for insertion in the first lumen and also dimensioned for insertion into a bronchial passageway.
Claim 13
Dependent Claim 27 words
11 . The system of claim 10 , wherein the delivery element is a bronchoscope and wherein the first lumen is a working channel of the bronchoscope.
Claim 14
Dependent Claim 33 words
12 . The system of claim 10 , wherein the means for controlling includes a one-way valve that permits fluid flow in a first direction and prevents fluid flow in a second direction.
Claim 15
Dependent Claim 18 words
13 . The system claim 10 , wherein the means for controlling is configured to block fluid flow.
Claim 16
Dependent Claim 18 words
14 . The system of claim 10 , wherein the means for controlling includes an expandable support structure.
Claim 17
Dependent Claim 16 words
15 . The system of claim 14 , wherein the expandable support structure comprises a frame.
Claim 18
Dependent Claim 15 words
