Abstract
An oxygenator apparatus for use in an extracorporeal circuit. The apparatus includes a housing and a membrane assembly disposed within the housing. The membrane assembly includes a first plurality of gas exchange elements disposed in a first zone and a second plurality of gas exchange elements disposed in a second zone. The second zone is arranged concentrically around the first zone. The first and second plurality of gas exchange elements are fluidly open along a body and fluidly separated along a distal end. The first zone is configured to be fluidly coupled to an oxygen source and the second zone is configured to be fluidly coupled to a negative pressure source. A blood flow path includes a generally radial flow through the first zone to add oxygen to the blood and the second zone to separate gaseous micro emboli from the blood through the plurality of gas exchange elements.
