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. The device further includes an axially extending radiopaque stripe extending along the tube at a location 180.degree. from the second lumen.
