Abstract

An extracorporeal blood pump assembly includes a blood pump and an extracorporeal membrane oxygenator (ECMO). The blood pump includes a pump housing, a rotor, and a flow converter positioned downstream from the rotor to convert non-axial flow from the rotor to axial flow. The pump housing defines an inlet and an outlet. The ECMO includes a membrane housing and an oxygenator membrane disposed within the membrane housing. The membrane housing is removably connected to the pump housing at one of the pump housing inlet and the pump housing outlet.
