Bronchial obstruction device deployment system and method

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.

What is claimed is:  
     
         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 1  wherein the capsule includes a break-away end portion to release the bronchial obstruction device.  
     
     
         4 . The system of  claim 1  further including a pusher that pushes the bronchial obstruction device from the capsule.  
     
     
         5 . The system of  claim 1  further including an elongated extension communicating with the capsule and dimensioned for receiving the pusher.  
     
     
         6 . The system of  claim 5  further including a break-away wall between the capsule and the elongated extension.  
     
     
         7 . The system of  claim 1  wherein the capsule is formed of flexible material for collapsing within the internal lumen.  
     
     
         8 . The system of  claim 1  wherein the capsule is formed of a rigid material.  
     
     
         9 . 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.  
     
     
         10 . The system of  claim 9  wherein the distal end of the capsule has a rounded shape.  
     
     
         11 . The system of  claim 1  wherein the conduit is one of a bronchoscope and a catheter.  
     
     
         12 . 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.    
     
     
         13 . The system of  claim 12  wherein the deployment means sealingly houses the bronchial obstruction device.  
     
     
         14 . The system of  claim 12  wherein the distal end of the deployment means includes a break-away portion for releasing the bronchial obstruction device.  
     
     
         15 . The system of  claim 12  further including pushing means for pushing the bronchial obstruction device from the deployment means.  
     
     
         16 . The system of  claim 12  wherein the deployment means includes an elongated extension dimensioned for receiving the pushing means.  
     
     
         17 . The system of  claim 16  further including a break-away wall between the elongated extension and the deployment means.  
     
     
         18 . The system of  claim 12  wherein the deployment means is formed of flexible material for collapsing within the internal lumen.  
     
     
         19 . The system of  claim 12  wherein the deployment means is formed of a rigid material.  
     
     
         20 . The system of  claim 12  wherein the distal end of the deployment means has a rounded shape.  
     
     
         21 . The system of  claim 12  wherein the lumen means is one of a bronchoscope and a catheter.  
     
     
         22 . 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.    
     
     
         23 . The method of  claim 22  wherein the placing step includes the step of sealing the bronchial obstruction device in the housing.  
     
     
         24 . The method of  claim 22  wherein the releasing step includes the step of breaking-away a portion of the housing.  
     
     
         25 . The method of  claim 22  wherein the releasing step includes the step of pushing the bronchial obstruction device from the housing.
