Abstract
In accordance with some non-limiting examples of the disclosed subject matter, a method of reducing pneumothorax in a percutaneous lung procedure using a cannula having a lumen extending from a first opening to a second opening and having a third opening arranged along a length of the lumen is provided. The reservoir containing a liquid sealant is coupled to the third opening of the cannula. While the cannula is arranged within a subject such that the second opening of the lumen opens into a pleural cavity of the subject, the liquid sealant is injected from the reservoir into the lumen such that the liquid sealant flows out of the second opening of the cannula into the pleural cavity. With liquid sealant sealing the pleural cavity, the cannula is withdrawn from the pleural cavity such that air is unable to infiltrate the pleural cavity by way of the liquid sealant.
