Abstract
In a centrifugal flow blood pump, usable in left ventricular assist applications, blood is pumped from an inlet () to an outlet () by a primary impeller (). A portion of the blood that enters the pump follows a secondary channel () where a secondary impeller () routes the blood to lubricate a bearing between an impeller assembly () and a post formed by a component of the pump housing. The unique shape of the secondary impeller () prevents blood stagnation and provides for a well-washed fluid bearing.
