Claim 0:
1. A method of modifying a component in an extracorporeal membrane oxygenation (ECMO) system during operation of the ECMO system, the component being in fluid communication with a connector having a tubular body with an inner surface that defines a lumen extending therethrough, wherein the ECMO system comprises an active bypass extending between an inlet and an outlet, and an active pathway extending between the inlet and the outlet and in fluid communication with the lumen, the connector having a first closure mechanism and a second closure mechanism and a connection interface engaged with the component, and the active bypass having a first bypass closure mechanism and a second bypass closure mechanism, wherein each of the first and second closure mechanisms are configured to have an open configuration in which the first and second closure mechanisms, respectively, do not obstruct the lumen and a closed configuration in which the first and second closure mechanisms, respectively, obstruct the active bypass, and wherein each of the first and second bypass closure mechanisms are configured to have an open configuration in which the first and second bypass closure mechanisms, respectively, do not obstruct the active bypass and a closed configuration in which the first and second bypass closure mechanisms, respectively, obstruct the active bypass,
the method comprising:
opening the active bypass such that fluid flows simultaneously through the active bypass and the active pathway from the inlet to the outlet, wherein opening the active bypass includes switching the first bypass closure mechanism from the closed configuration to the open configuration such that fluid flows into the active bypass at the inlet, and switching the second bypass closure mechanism from the closed configuration to the open configuration such that fluid flows out of the active bypass at the outlet;
closing the active pathway while fluid flows through the active bypass from the inlet to the outlet, wherein closing the active pathway includes switching the first closure mechanism from the open configuration to the closed configuration such that fluid flow through the lumen is obstructed by the first closure mechanism, and switching the second closure mechanism from the open configuration to the closed configuration such that fluid flow through the lumen is obstructed by the second closure mechanism; and
disconnecting the component from the ECMO system by disengaging the component from the connection interface of the connector;
wherein switching the first closure mechanism comprises switching a pinch clamp from an open configuration to a closed configuration and switching the second closure mechanism comprises turning a turn valve from an open configuration to a closed configuration.
