This paper is concerned with the development of an artificial urethral valve for treating urinary incontinence, which is driven by the shape memory alloy actuator. A non-contact, compact induction heating system using the power transmission coils is introduced, which is consisting of the oscillation, regular voltage, amplifier and transmission circuits. It transmits the electric power to the artificial valve inside the body transcutaneously. The transformer is designed so that it is driven by the battery considering that it be used outside the buildings. From the experimental results, it is shown that the proposed transformer system driven by the battery supplies enough power to the urethral valve to open the choked urethra.
