Adult and pediatric extracorporeal life support system with heparin treated oxygenator surface and magnetic levitation motor

An integrated blood pump oxygenator system comprising:

• a central housing member defining a blood inlet and a central blood flow path extending along a general longitudinal axis of the system;
• a center pump housing member coupled to the central housing member and defining a pump inlet in fluid communication with the central blood flow path;
• an impeller rotationally received within the area of the pump inlet formed by the central pump housing member, wherein the impeller is magnetically supported and magnetically driven;
• an array of hollow fiber membranes configured for gas transfer within the system for oxygenation of blood flowing radially outwardly across the array of the hollow fiber membranes, wherein each of the hollow fiber membranes of the array of the hollow fiber membranes includes a covalently-bonded heparin-based bioactive surface, and wherein the central blood flow path extends from the impeller to a position to flow radially outwardly perpendicular over the array of the hollow fiber membranes;
• and
• a blood outlet configured to receive the blood flowing radially outwardly past the array of the hollow fiber membranes.
