Abstract
A catheter pump is disclosed herein. The catheter pump can include a catheter assembly that comprises a drive shaft and an impeller coupled to a distal end of the drive shaft. A driven assembly can be coupled to a proximal end of the drive shaft within a driven assembly housing. The catheter pump can also include a drive system that comprises a motor and a drive magnet coupled to an output shaft of the motor. The drive system can include a drive assembly housing having at least one magnet therein. Further, a securement device can be configured to prevent disengagement of the driven assembly housing from the drive assembly housing during operation of the pump.

1-20. (canceled)
A heart pump for a medical patient, the heart pump comprising:
- a catheter body;
- a percutaneously insertable impeller disposed at a distal portion of the catheter body and positionable through a vasculature of the medical patient to a desired location;
- a motor operably coupled to the percutaneously insertable impeller through a flexible drive cable, wherein the motor includes a damping component configured to reduce at least one of vibration and noise associated with operation of the motor as it rotates the percutaneously insertable impeller to pump blood and therefore assists a blood pumping function of the heart.
