摘要： A catheter pump includes a cannula having an inlet, an outlet, and a blood flow channel extending between the inlet and the outlet along a longitudinal axis. At least one impeller blade is operable to convey blood through the blood flow channel between the inlet to the outlet, wherein the at least one impeller blade is axially movable relative the cannula in a first direction toward the inlet and in a second direction away from the inlet.

摘要： 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.

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.
