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 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 so as to release the bronchial obstruction device in the air passageway upon a proximal force being exerted upon said bronchial obstruction device.

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

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

guiding a conduit down a trachea into the air passageway;

advancing a capsule having a bronchial device therein down an internal lumen of the conduit into the air passageway;

releasing the bronchial device from the capsule; and

deploying the bronchial device into the air passageway.

4. The method of claim 3 wherein the capsule comprises a breakable seam from which the bronchial device can be released.

5. The method of claim 3 further comprising pushing the bronchial device from the capsule.
