It is well known that the cost of artificial heart is more expensive than other cardiovascular devices and its cost still tends to increase. The cost is one of the important factors to be chosen by the doctors, patients and their families. Therefore, vacuum forming technique has been adopted to fabricate the spiral vortex pump to achieve lower fabrication cost. First of all, optimal conditions of vacuum forming were investigated and it became possible to fabricate well quality components of the spiral vortex pump. Next, a polymer Jellyfish valve and Medtronic-Hall valve were incorporated into the spiral vortex pump to compare their hydrodynamic performance. At last, throughout the blood compatibility test, MPC coating exhibited a favorable effect to eliminate thrombus inside the pump. From the result of all, it was possible to fabricate a pulsatile blood pump at lower price and new method of closed circuit of blood compatibility method was useable in developing process of artificial heart.
