Abstract
The present invention is a tapered attachment for use with a pleural catheter that connects securely to the pleural catheter and has a hollow elongated member and a tapered distal portion. When the tapered attachment connected to the prior art catheter, the hollow elongated member opens the self-sealing valve of the prior art catheter allowing communication from the interior of the pleural catheter to the interior of the tapered attachment. The distal outer taper of the invention can connect to a variety of standard drainage systems to remove fluids or gases from the pleural cavity. The invention may also have a one way valve. With the invention in place and functioning, air does not enter the pleural space. Additionally, the variations in pleural pressure that normally occur during respiration can pump fluids or gases out of the pleural cavity through the invention.
