Abstract
A percutaneous circulatory support device includes a housing having an inlet and an outlet. A shaft is rotatably fixed relative to the housing. An impeller is disposed within the housing and is rotatably supported by the shaft. The impeller is configured to rotate relative to the shaft and the housing to cause blood to flow into the inlet, through the housing, and out of the outlet. A keeper is coupled to the shaft distally relative to the impeller, and the keeper inhibits axial motion of the impeller relative to the shaft.
