Zusammenfassung:	A drive unit for intravascular circulatory support systems may include a motor, a ball nut, a ball screw, and a bellows. The motor may include a rotor and a stator. The ball nut may be affixed to the rotor. The bellows may have a first end and an second end and a bellows cavity located there between. The first end may be in fixed position and the second end may be defined by a dynamic flange having a recess carried by the bellows cavity. In turn, the recess of the dynamic flange may carry at least a portion of the motor. The second end may also receive the ball screw. Rotation of the rotor causes linear motion of the ball screw within the ball nut to actuate the bellows.
