1. A drainage assembly configured to prevent negative pressure build-up, comprising:

  • an elongate catheter having a first end configured for insertion within a body lumen, the catheter having at least one opening near or at the first end in fluid communication with a catheter lumen defined therethrough;

    a drainage lumen in fluid communication with a second end of the catheter;

    a reservoir in fluid communication with the drainage lumen;

    a venting mechanism in fluid communication with the drainage lumen and a positive pressure lumen;

    a valve positioned within the venting mechanism and configured to maintain a closed position until a first pressure level within the drainage lumen drops to a second pressure level such that the valve moves to an open position;

    a vent positioned in fluid communication with the valve, wherein the venting mechanism is configured to inhibit wetting of the vent from fluid within the drainage lumen; and

    a controller in communication with the reservoir, wherein the controller is configured to determine a fluid volume collected within the reservoir.
