A ventricular assist device, comprising a motor (600), a catheter (100), a driving shaft (400) rotatably passing through the catheter (100), a pump head (200), and a protection tip (300). The pump head (200) comprises a pump housing (210) connected to the distal end of the catheter (100), and an impeller (220) received in the pump housing (210) and connected to the distal end of the driving shaft (400). The protection tip (300) is provided at the distal end of the pump housing (210) and comprises a proximal section (310) connected to the distal end of the pump housing (210), a distal section (320) distant from the pump housing (210), and a middle section (330) connecting the proximal section (310) and the distal section (320). The outer diameter of the proximal section (310) is greater than that of the distal section (320), and the outer diameter of the middle section (330) is gradually reduced in the near-to-far direction.
