Abstract:
1. An apparatus for treatment of a pleural effusion comprising: a tube, said tube having a distal end adapted to communicate with fluids within a patient's body when placed in communication therewith in a mounted position, and having a first end opposite said distal end; an axial cavity communicating between said first end and said distal end; a valve, said valve having a valve conduit communicating between a first end and a second end; said first end of said valve conduit in a sealed engagement with said axial cavity at said first end of said tube; said valve defaulting to a closed position preventing communication through said valve conduit to said axial cavity; said valve having an open position wherein said axial cavity communicates with said second end of said valve conduit; said valve activated from said closed position to said open position by a communication of negative pressure to said second end of said valve conduit; said negative pressure communicated to said second end of said valve conduit initiating a fluid flow in said axial cavity in a direction only toward said first end of said axial cavity, when said valve is in said open position; and said valve in said closed position, providing a means to prevent said fluid flow from reversing said direction.
