摘要

A catheter pump assembly is provided that includes an elongate body, an elongate flexible shaft disposed in the elongate body, and an impeller coupled with the distal end of the elongate flexible shaft. The drive system includes a drive component, a motor and a tension member. The tension member is coupled with the motor and the drive component and to cause the drive component to rotate, and thereby to cause the impeller to rotate.
