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 self-expandable bronchial obstruction device in an air passageway comprising:

a catheter configured to be passed down the trachea;

a sealed capsule for housing the self-expandable bronchial obstruction device in a sterile environment, the capsule being configured to be advanced down the catheter and comprising a tubular extension, the capsule having a breakable seam opened by the self-expandable bronchial obstruction device so as to release the bronchial obstruction device in the air passageway upon a proximal force being exerted upon said self-expandable bronchial obstruction device,

wherein the self-expandable bronchial obstruction device is a one-way valve configured to preclude inhaled air from entering an area of the air passageway while allowing air within the area of the air passageway to be exhaled.

2. The apparatus of claim 1 wherein the capsule is formed of flexible material for collapsing within the catheter.

3. The apparatus of claim 1, wherein the sealed capsule comprises a flexible, biocompatible material.

4. The apparatus of claim 1, wherein the sealed capsule comprises a rounded distal end to minimize friction.

5. The apparatus of claim 1, wherein the breakable seam comprises a score or notch.

6. The apparatus of claim 1, wherein the proximal force is applied by a distal end of the sealed capsule.

7. The apparatus of claim 1, further comprises a pusher for engaging the self-expandable bronchial obstruction device.

8. The apparatus of claim 7, wherein the pusher is configured to enable the self-expandable bronchial obstruction device to open the breakable seam.

9. The apparatus of claim 7, wherein the pusher is configured to apply a distal force on the self-expandable bronchial obstruction device to open the breakable seam.

10. The apparatus of claim 7, wherein the pusher comprises a disc-shaped distal end.

11. A method of deploying a bronchial device in an air passageway comprising:

guiding a conduit down a trachea into the air passageway;

advancing a sealed capsule having a sterile environment for storing a self-expandable bronchial obstruction device therein down an internal lumen of the conduit into the air passageway, the sealed capsule having a breakable seam opened by the self-expandable bronchial obstruction device, wherein the self-expandable bronchial obstruction device is a one-way valve configured to preclude inhaled air from entering an area of the air passageway while allowing air within the area of the air passageway to be exhaled;

releasing the self-expandable bronchial obstruction device from the sealed capsule when a proximal force is exerted on the self-expandable bronchial obstruction device; and

deploying the self-expandable bronchial obstruction device into the air passageway.

12. The method of claim 11 further comprising pushing the bronchial device from the capsule.

13. The method of claim 11, wherein the sealed capsule comprises a flexible, biocompatible material.

14. The method of claim 11, wherein the sealed capsule comprises a rounded distal end to minimize friction.

15. The method of claim 11, wherein the breakable seam comprises a score or notch.

16. The method of claim 11, wherein the proximal force is applied by a distal end of the sealed capsule.

17. The method of claim 11, wherein the releasing further comprises engaging the self-expandable bronchial obstruction device with a pusher.

18. The apparatus of claim 17, wherein the pusher is configured to enable the self-expandable bronchial obstruction device to open the breakable seam.

19. The apparatus of claim 17, wherein the pusher is configured to apply a distal force on the self-expandable bronchial obstruction device to open the breakable seam.

20. The apparatus of claim 17, wherein the pusher comprises a disc-shaped distal end.
