Abstract

Abstract An air passageway obstruction device includes a frame structure and a flexible membrane overlying the frame structure. The frame structure is collapsible upon advancement of the device into the air passageway, expandable into a rigid structure upon deploying in the air passageway and re-collapsible upon removal from the air passageway. The flexible membrane obstructs inhaled air flow into a lung portion communicating with the air passageway. The device may be removed after deployment in an air passageway by re-collapsing the device and pulling the device proximally through a catheter.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 104 words
1 . An intra-bronchial valve device configured to be implanted within an air passageway of a lung, the device comprising: a frame comprising a plurality of elongate frame supports joined to one another at first and second attachment points, wherein each frame support assumes an at-rest shape with a substantially straight center portion and a pair of oppositely extending inwardly arcuate end portions; and a flexible membrane disposed on the frame and covering at least portions of the frame supports, the membrane being sealed to the frame to prevent airflow between a first side of the membrane and a second side of the membrane.
Claim 2
Dependent Claim 104 words
1 . An intra-bronchial valve device configured to be implanted within an air passageway of a lung, the device comprising: a frame comprising a plurality of elongate frame supports joined to one another at first and second attachment points, wherein each frame support assumes an at-rest shape with a substantially straight center portion and a pair of oppositely extending inwardly arcuate end portions; and a flexible membrane disposed on the frame and covering at least portions of the frame supports, the membrane being sealed to the frame to prevent airflow between a first side of the membrane and a second side of the membrane.
Claim 3
Dependent Claim 59 words
2 . The device of claim 1 , wherein the membrane is attached to the supports so as to preclude airflow from the concave side to the convex side of the membrane while permitting air to flow from the convex side to the concave side along a path between the membrane and a portion of an air passageway wall.
Claim 4
Dependent Claim 25 words
3 . The intra-bronchial valve of claim 1 , wherein the first and second attachment points are located at ends of the elongate support members.
Claim 5
Dependent Claim 19 words
4 . The intra-bronchial valve of claim 1 , wherein the elongate support members comprise sections of resilient wire.
Claim 6
Dependent Claim 26 words
5 . The intra-bronchial valve of claim 1 , wherein the first attachment point of the frame is configured to be engaged by a retractor device.
Claim 7
Dependent Claim 28 words
6 . The intra-bronchial valve of claim 5 , wherein the frame is configured such that pulling the frame into a catheter lumen causes the frame to collapse.
Claim 8
Dependent Claim 40 words
7 . The intra-bronchial valve of claim 1 , further comprising at least one anchor member extending from the first or the second attachment point, said anchor member being configured to directly engage a portion of the air passageway wall.
Claim 9
Dependent Claim 21 words
8 . The intra-bronchial valve of claim 7 , wherein the anchor member extends from a distal end of the frame.
Claim 10
Dependent Claim 23 words
9 . The intra-bronchial valve of claim 7 , wherein the anchor member is configured to puncture portions of the air passageway wall.
Claim 11
Dependent Claim 123 words
10 . An intra-bronchial valve device comprising: a frame comprising a plurality of elongate frame supports having first and second ends joined by at first and second common attachment points; a flexible membrane disposed on the frame and covering at least portions of the frame supports, the membrane having a concave side and a convex side; wherein the device is configured to be implanted within an air passageway of a patient, and wherein the membrane is attached to the supports so as to preclude airflow from the concave side to the convex side of the membrane while permitting air to flow from the convex side to the concave side along a path between the membrane and a portion of an air passageway wall.
Claim 12
Dependent Claim 123 words
10 . An intra-bronchial valve device comprising: a frame comprising a plurality of elongate frame supports having first and second ends joined by at first and second common attachment points; a flexible membrane disposed on the frame and covering at least portions of the frame supports, the membrane having a concave side and a convex side; wherein the device is configured to be implanted within an air passageway of a patient, and wherein the membrane is attached to the supports so as to preclude airflow from the concave side to the convex side of the membrane while permitting air to flow from the convex side to the concave side along a path between the membrane and a portion of an air passageway wall.
Claim 13
Dependent Claim 32 words
11 . The intra-bronchial valve of claim 10 , wherein the frame assumes an at-rest shape with a substantially cylindrical center portion and a pair of oppositely extending inwardly arcuate end portions.
Claim 14
Dependent Claim 32 words
12 . The intra-bronchial valve of claim 10 , wherein the frame is configured to be engaged by a retractor device and to be pulled into a lumen of a removal catheter.
Claim 15
Dependent Claim 28 words
13 . The intra-bronchial valve of claim 12 , wherein the frame is configured such that pulling the frame into a catheter lumen causes the frame to collapse.
