Mechanical multi-stage connection and disconnection maintaining sterile barrier

A decontamination system for a lumen device, the decontamination system comprising:

• a decontamination chamber defining a lumen device receiving area;
• a terminal package dimensioned to be received within the lumen device receiving area, wherein the terminal package is configured to establish a sterile barrier for an interior of the terminal package;
• a connector assembly operably associated with the terminal package, wherein the connector assembly comprises:
• a main body defining a fluid passageway to establish fluid communication with the interior of the terminal package;
• a multistage barrier movable in the fluid passageway between a fully closed position in which each stage of the multistage barrier is in a closed position in which each stage independently blocks flow in the fluid passageway and a fully open position in which each stage is in an open position to allow flow within the fluid passageway;
• a connector configured to be coupled with the main body, wherein the connector is configured to engage the multistage barrier when coupled to the main body to sequentially open each stage of the multistage barrier to enable fluid communication between the connector and the interior of the terminal package;
• and
• one or more biasing members configured to urge each stage of the multistage barrier towards a closed position that blocks flow in the fluid passageway.
