1. A veno-arterial extracorporeal membrane oxygenation (VA ECMO) system comprising:
a dual lumen drainage cannula comprising:
a first drainage tube configured for fluid drainage from a first portion of a cardiopulmonary system; and
a second drainage tube aligned with the first drainage tube and configured for fluid drainage from a second portion of the cardiopulmonary system;
a blood pump having a pump inlet and a pump outlet, the pump inlet configured for fluidly connecting with the first drainage tube and the second drainage tube;
an oxygenator having an oxygenator inlet and an oxygenator outlet, the oxygenator inlet configured for fluidly connecting with the pump outlet; and
an infusion cannula configured for fluidly connecting with the oxygenator outlet;
wherein a distal end of the second drainage tube is fixedly connected to the first drainage tube.
