The invention discloses a ventricular assist device and a manufacturing method of the ventricular assist device, and the ventricular assist device comprises an axial flow pump body and a pigtail tube body arranged at the far end of the axial flow pump body; the pigtail tube body comprises a bending part located at the far end and a supporting part located at the near end; at least partial section of the far end of the bent part is a bent pipe in a natural state, and the bent part can be roughly straightened under the action of external force; at least partial section of the far end of the bending part is a reducing section; the material of the bending part has first hardness; the supporting part is of a straight pipe structure in the natural state, and the material of the supporting part has the second hardness larger than the first hardness. The pigtail tube is divided into the supporting part and the bending part, the hardness of the supporting part is larger than that of the bending part, so that the pigta
