Abstract

A veno-arterial extracorporeal membrane oxygenation system includes a dual lumen drainage cannula configured for withdrawing blood from a patient's vasculature in a manner that provides a perfusion of oxygenated blood with reduced carbon dioxide content while unloading the left ventricle, with two points of access to the patient's vasculature. The dual lumen drainage cannula has a first drainage tube and a second drainage tube co-axially aligned with the first drain-age tube. The first and second drainage tubes are fluidly coupled to a connector. A blood pump having a pump inlet is configured for fluidly connecting with the connector, while an oxygenator having an oxygenator inlet is configured for fluidly connecting with a pump outlet. An infusion cannula is configured for fluidly connecting with an oxygenator outlet for infusing oxygenated blood into a patient's bloodstream.
