1. A multi-lumen coupling system, comprising:
a primary multi-lumen coupler (MLC) assembly;
a secondary MLC assembly attachable to the primary MLC assembly; and
an occluding mechanism disposed between a proximal end and a distal end of the primary MLC assembly to block fluid flow therebetween,
wherein the occluding mechanism is configured to block fluid flow in the primary MLC assembly prior to a detachment of the secondary MLC assembly from the primary MLC assembly by a rotation of the secondary MLC assembly.
