First Claim
1. A medical device for performing a bronchoalveolar lavage (BAL), comprising:
- a tubing havinga first lumen configured for communication with a first reservoir, the first lumen having an open distal end configured for communication with the first reservoir,a second lumen that is separate from the first lumen and configured for communication with a second reservoir, andan inflatable cuff that is disposed proximate the open distal end and configured for communication with the second reservoir via the second lumen, wherein the open distal end and the inflatable cuff in a deflated position are both configured for receipt within a working channel of a bronchoscope.

Abstract
A medical device for performing a bronchoalveolar lavage (BAL) that includes a tubing having a first lumen configured for communication with a first reservoir, the first lumen having an open distal end configured for communication with the first reservoir, and a second lumen that is separate from the first lumen and configured for communication with a second reservoir. The tubing also includes an inflatable cuff that is disposed proximate the open distal end and configured for communication with the second reservoir via the second lumen, wherein the open distal end and the inflatable cuff in a deflated position are both configured for receipt within a working channel of a bronchoscope.

7. A method for performing a bronchoalveolar lavage (BAL), comprising:
-
inserting a movable tubing with an inflatable cuff in a deflated position into an air passageway of a subject; positioning the movable tubing in the air passageway by visually monitoring an image of a distal portion of the tubing inserted into the air passageway; insufflating the inflatable cuff to an inflated position to create a wedge to seal off an area of the air passageway; and aspirating a lavage fluid specimen from the sealed-off area through the tubing. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 21, 22)

16. A method for performing an endobronchial balloon tamponade of pulmonary hemorrhage, comprising:
-
inserting a bronchoscope with a working channel housing a movable tubing into an air passageway of a subject; positioning the bronchoscope in the air passageway; extending the tubing beyond a positioned distal tip of the bronchoscope to a desired position in the air passageway; and insufflating in the air passageway an inflatable cuff positioned proximate a distal end of the tubing. - View Dependent Claims (17, 18, 19, 20)
