Abstract

A system and method deploys a bronchial obstruction device in an air passageway communicating with a lung portion to be at least temporarily collapsed. The system includes a conduit 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 system further includes a capsule dimensioned to house the bronchial obstruction device and to be advanced down an internal lumen of the conduit into the air passageway. The capsule has a break-away distal end configured to release the bronchial obstruction device for deployment in the air passageway upon being pushed from the capsule by a pusher member.

Claims

1. A system for deploying a bronchial obstruction device in an air passageway communicating with a lung portion to be at least temporarily collapsed by the bronchial obstruction device, the system comprising:

a conduit 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 conduit having an internal lumen; and

a capsule dimensioned to house the bronchial obstruction device and to be advanced down the internal lumen into the air passageway, the capsule being configured to release the bronchial obstruction device for deployment in the air passageway.

2. The system of claim 1 wherein the capsule sealingly houses the bronchial obstruction device.

3. The system of claim 2, wherein the sealed chamber maintains sterility of the obstruction device until broken.

4. The system of claim 1 wherein the capsule includes a break-away end portion to release the bronchial obstruction device.

5. The system of claim 1 further including a pusher that pushes the bronchial obstruction device from the capsule.

6. The system of claim 1 further including an elongated extension communicating with the capsule and dimensioned for receiving the pusher.

7. The system of claim 5 further including a break-away wall between the capsule and the elongated extension.

8. The system of claim 1 wherein the capsule is formed of flexible material for collapsing within the internal lumen.

9. The system of claim 1 wherein the capsule is formed of a rigid material.

10. The system of claim 1 wherein the capsule includes a distal end and wherein the distal end of the capsule is configured to release the bronchial obstruction device.

11. The system of claim 10 wherein the distal end of the capsule has a rounded shape.

12. The system of claim 1 wherein the conduit is one of a bronchoscope and a catheter.

13. A system for deploying a bronchial obstruction device in an air passageway communicating with a lung portion to be at least temporarily collapsed by the bronchial obstruction device, the system comprising:

a lumen means for being passed down a trachea, into a bronchus communicating with the trachea and into the air passageway communicating with the lung portion; and

deployment means for housing the bronchial obstruction device and dimensioned for advancement down the lumen means into the air passageway, the deployment means having a distal end for releasing the bronchial obstruction device within the air passageway.

14. The system of claim 13 wherein the deployment means sealingly houses the bronchial obstruction device.

15. The system of claim 14, wherein the sealed enclosure means maintains sterility of the obstruction device until broken.

16. The system of claim 13 wherein the distal end of the deployment means includes a break-away portion for releasing the bronchial obstruction device.

17. The system of claim 13 further including pushing means for pushing the bronchial obstruction device from the deployment means.

18. The system of claim 13 wherein the deployment means includes an elongated extension dimensioned for receiving the pushing means.

19. The system of claim 18 further including a break-away wall between the elongated extension and the deployment means.

20. The system of claim 13 wherein the deployment means is formed of flexible material for collapsing within the internal lumen.

21. The system of claim 13 wherein the deployment means is formed of a rigid material.

22. The system of claim 13 wherein the distal end of the deployment means has a rounded shape.

23. The system of claim 13 wherein the lumen means is one of a bronchoscope and a catheter.

24. A method of deploying a bronchial obstruction device in an air passageway communicating with a lung portion to be at least temporarily collapsed, the method including the steps of:

placing the bronchial obstruction device in a housing;

guiding a conduit having an internal lumen down a trachea, into a bronchus communicating with the trachea and into the air passageway communicating with the lung portion;

advancing the housing down the internal lumen of the conduit into the air passageway; and

releasing the bronchial obstruction device from the housing to deploy the bronchial obstruction device in the air passageway.

25. The method of claim 24 wherein the placing step includes the step of sealing the bronchial obstruction device in the housing.

26. The method of claim 24 wherein the releasing step includes the step of breaking-away a portion of the housing.

27. The method of claim 24 wherein the releasing step includes the step of pushing the bronchial obstruction device from the housing.

28. A method of deploying a bronchial device in an air passageway, the method including the steps of:

guiding a conduit having an internal lumen down a trachea, into a bronchus communicating with the trachea, and into the air passageway communicating with the lung portion;

advancing a capsule containing the bronchial device down the Internal lumen of the conduit into the air passageway, the capsule having a housing arranged to maintain a sterility of the bronchial device; and

releasing the bronchial device from the capsule to deploy the bronchial device in the air passageway.

29. The method of claim 28, wherein the releasing step further includes a step of breaking the housing.

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

a breakable capsule arranged to house and to maintain sterility of the bronchial device,

the capsule being further arranged to be advanced down an internal lumen of a catheter placed into the air passageway and upon being broken to release the bronchial device for deployment in the air passageway.

31. The apparatus of claim 30, wherein the breakable capsule further includes a sealed chamber for maintaining the sterility of the bronchial device.

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

a conduit 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 conduit having an internal lumen; and

a capsule arranged to house and to maintain a sterility of the bronchial device, and dimensioned to be advanced down the internal lumen into the air passageway, the capsule being further arranged to release the bronchial device for deployment in the air passageway.

33. The system of claim 32, wherein the capsule includes a sealed chamber for maintaining the sterility the bronchial device.

34. The system of claim 32, wherein the capsule includes a break-away end portion for releasing the bronchial device.
