Abstract: A catheter device useful for treatment of the pleural space. The device includes a catheter tube having an internal end and an external end and is sized for use in the pleural space. The tube has a central bore forming a first lumen with a flared suction engaging portion on the external end and a tapered portion on the internal end for providing access to the pleural space. Also included is a stylette sized for insertion in the first lumen, the stylette having less flexibility than the tube. Forming part of the device is a second lumen axially extending in the catheter tube from the external end to a closed terminal point proximate the internal end of the tube and having a substantially smaller diameter than the first lumen, the second lumen having at least one opening proximate the closed terminal point, the second lumen being fitted with a flexible tube having an injection port at its exterior end and an open end bonded to the internal wall of the second lumen.
