The Intra‐Aortic Balloon Pump (IABP) is an effective device in assisting circulation. However, a small‐sized IABP is required in related fields. This paper proposes a new small‐sized IABP which is driven by a Linear Pulse Motor (LPM) rather than an air‐driven motor. In general, the LPM has advantages of high thrust/input power and good controllability. The developed LPM for the IABP drive has high thrust/input power of 19.9 newtons/W. It also has kinetic thrust of 270 newtons at the range of speed from 100 to 140 mm/s. The IABP using the LPM has an extremely simple construction. As the result of mock testing, the IABP using an LPM not only gives the same performance as the ordinary air‐driven IABP, but the mass of the IABP will be reduced to half the size of the ordinary one.
