PLEURAL DRAINAGE SYSTEM AND METHOD OF USE

摘要

A pleural drainage system having an inflatable membrane and a method of using the system are disclosed. The pleural drainage system includes a pleural drainage catheter system. The pleural drainage catheter system includes an inflatable membrane and a drainage catheter integrally coupled to the inflation membrane, the drainage catheter defining a drainage lumen through which fluid is drawn from the pleural cavity, and an inflation lumen coupled for flow of inflation fluid to and from an interior of the inflatable membrane. The pleural drainage system further includes a suction system coupled to the drainage catheter and a fluid collector coupled to receive fluid from the drainage catheter. The pleural drainage system further includes an inflation system connected to deliver inflation fluid to the interior of the inflatable membrane. The pleural drainage system may be used to monitor an associated airleak in the pleural cavity of a patient.

主权项

1. A pleural drainage catheter system configured to extend into a pleural cavity of a patient and to drain fluid from the pleural cavity of the patient, said pleural drainage catheter system comprising:
an inflatable membrane comprising two opposed layers formed from a bio-compatible material, the inflatable membrane having a deflated state in which the layers are positioned substantially adjacent one another and an inflated state in which at least portions of the respective layers are spaced from one another, an external surface of the inflatable membrane defining one or more passages that facilitate the movement of fluid along the external surface for removal from the pleural cavity when the inflatable membrane is in the inflated state; and a drainage catheter integrally coupled to the inflatable membrane, the drainage catheter defining a drainage lumen, a plurality of drainage openings through which fluid is drawn into the drainage lumen from the pleural cavity, and an inflation lumen coupled for flow of inflation fluid to and from an interior of the inflatable membrane.
