Abstract
A catheter pump includes a cannula and an impeller system. The cannula has an inlet zone with a first maximum outer diameter, an outlet zone with a second maximum outer diameter and a blood flow channel extending between the inlet zone and the outlet zone. The first maximum outer diameter is greater than the second maximum outer diameter, and the impeller system has a rotatable impeller body operable to convey blood from the inlet zone to the outlet zone. The impeller body may be axially spaced from the cannula in a separated position.
