Abstract

An apparatus and method deploy a self-expandable bronchial obstruction device in an air passageway. The apparatus includes a catheter configured to be passed down the trachea. The apparatus further includes a capsule for housing the self-expandable bronchial obstruction device in a sterile environment. The capsule is configured to be advanced down the catheter. The capsule further includes a tubular extension. The capsule has a breakable seam so as to release the bronchial obstruction device in the air passageway upon a proximal force being exerted upon the bronchial obstruction device. The method includes guiding a conduit down a trachea into the air passageway. The method further includes advancing a capsule having a bronchial device therein down an internal lumen of the conduit into the air passageway. The method further includes releasing the bronchial device from the capsule. The method further includes deploying the bronchial device into the air passageway.

Claims

1. An apparatus for deploying a bronchial device in an air passageway, the apparatus comprising:

a conduit configured to be passed down a trachea, the conduit comprising an internal lumen,

an axially-movable push rod within the internal lumen,

a housing that defines a sealed capsule that is movable relative to the conduit, the sealed capsule substantially sealingly enclosing and separating the bronchial device from an environment external to the capsule, the bronchial device positioned within the housing, and

the housing being further arranged to be advanced down the internal lumen of the conduit placed into the air passageway in the direction of a distal end of the housing and, upon movement of the axially-movable push rod from outside of the capsule into a proximal end of the sealed capsule and upon application of force by the axially-movable push rod on a proximal end of the bronchial device, the bronchial device is released through a distal end of the capsule for deployment in the air passageway such that the bronchial device is not in physical contact with the housing or the conduit once deployed.

2. The apparatus of claim 1, wherein the housing further comprises an openable feature through which the bronchial device is released.

3. The apparatus of claim 2, wherein the openable feature is opened by being broken.

4. The apparatus of claim 1, wherein the housing comprises a break-away portion through which the axially-movable push rod extends to contact the bronchial device.

5. The apparatus of claim 1, wherein the sealed capsule comprises an openable feature at one end and a break-away feature at a second end.

6. The apparatus of claim 5, wherein the push rod can break through the break-away feature to urge the bronchial device through the openable feature.

7. The apparatus of claim 1, wherein the push rod extends within a lumen defined within a tubular extension attached to the housing.

8. The apparatus of claim 7, wherein the tubular extension is configured to deform as the axially-movable push rod is advanced through the tubular extension.

9. The apparatus of claim 1, wherein the housing includes a flexible material for collapsing within an internal lumen of the conduit.

10. The apparatus of claim 1, wherein the axially-movable push rod is located outside of the capsule until the application of force onto the proximal end of the capsule.

11. The apparatus of claim 1, wherein the capsule is configured to be fully within the conduit.

12. The apparatus of claim 1, wherein the capsule is configured to be broken on both the proximal and distal ends.

13. The apparatus of claim 12, wherein upon movement of the axially-movable push rod from outside of the capsule, the axially-movable push rod breaks the proximal end of the capsule, contacts the bronchial device at a proximal end, and pushes against the proximal end of the bronchial device so that a distal end of the bronchial device breaks the distal end of the capsule.

14. The apparatus of claim 1, wherein the sealed capsule is located distal of the distal end of the axially-movable push rod prior to movement of the axially-movable push rod from outside of the sealed capsule into a proximal end of the sealed capsule.

15. A system for deploying a bronchial device in an air passageway, the system comprising:

a catheter configured to be passed down a trachea, into a bronchus communicating with the trachea and into the air passageway communicating with the lung portion, the catheter comprising an internal lumen;

an axially-movable pusher within the internal lumen;

a housing that defines a sealed capsule arranged to substantially sealingly encapsulate and separate the bronchial device from an environment external to the capsule, the housing configured to be fully within the catheter;

the pusher movable relative to the housing the bronchial device positioned within the sealed capsule, the housing being further arranged to be advanced down an internal lumen of the catheter placed into the air passageway in the direction of a distal end of the catheter, and to release the bronchial device, upon movement of the axially-movable pusher from outside of the capsule into a proximal end of the sealed capsule and upon application of a force on a proximal end of the bronchial device, for deployment through a distal end of the sealed capsule in the air passageway such that the bronchial device is not in physical contact with the housing or the catheter once deployed, the axially-movable pusher being located outside of the sealed capsule until the application of the force on the proximal end of the sealed capsule; and

the housing comprising a proximally extending tubular extension that is separated from the bronchial device by a wall defining the sealed capsule.

16. The system of claim 15, wherein the housing further comprises an openable end through which the bronchial device is released.

17. The system of claim 16, wherein the wall is breakable to place an inside of the capsule into communication with a lumen defined by the tubular extension.

18. The system of claim 15, wherein the housing comprises a break-away portion arranged upon breakage to release the bronchial device.

19. The apparatus of claim 15, wherein upon movement of the axially-movable pusher from outside of the capsule, the axially-movable pusher breaks the proximal end of the capsule, contacts the bronchial device at a proximal end, and pushes against the proximal end of the bronchial device so that a distal end of the bronchial device breaks the distal end of the housing.
