摘要：
Disclosed herein is a catheter pump that includes an expandable cannula and an impeller system. The expandable cannula defines a blood flow channel and includes an impeller blade zone, an inlet zone, and an outlet zone. The catheter pump further includes an impeller system including an impeller body, the impeller system movable relative to the expandable cannula along a longitudinal axis of the catheter pump. The catheter pump is selectively transitionable between a separated configuration in which the impeller body is axially spaced from the expandable cannula along the longitudinal axis, and an operational configuration in which the impeller body is positioned within the impeller blade zone of the expandable cannula.
