Abstract
The present invention provides thoracentesis catheter instruments having self-sealing valves utilized in invasive medical procedures. The thoracentesis instruments provide automatic sealing of a flow path by the self-sealing valve upon removal of a needle from a catheter. A drainage flow path to a pleural cavity is established by manual movement of another valve. The self-sealing valve prevents insertion of the needle through the valve and the catheter.
