1. A pleural drainage system configured to deliver a therapeutic treatment to the pleural cavity of a patient, said system comprising:
a pleural drainage catheter system including an inflatable membrane having a deflated state and an inflated state, the pleural drainage catheter system also including a drainage catheter 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, wherein the inflatable membrane extends both proximally and distally with respect to the plurality of drainage openings, and wherein the inflatable membrane comprises a surface extending away from the drainage catheter adjacent one or more of the plurality of drainage openings, and inflatable, portions proximal and distal to the surface, the inflatable portions extending outwardly from the surface when the inflatable membrane is in the inflated state; a suction system coupled to the drainage catheter of the pleural drainage catheter system and connected to apply suction to the drainage lumen of the drainage catheter and to draw fluid into the drainage lumen of the drainage catheter through the drainage openings defined by the drainage catheter; a fluid collector coupled to receive fluid from the drainage lumen of the drainage catheter; and an inflation system coupled to the drainage catheter of the pleural drainage catheter system and connected to apply pressure to the inflation lumen of the drainage catheter and to deliver inflation fluid to the interior of the inflatable membrane through the inflation lumen defined by the drainage catheter. |
