Abstract
The method to control the ferromagnetic drugs in the patient body using magnetic force has been studied in order to improve the efficiency of the drug treatment. In the conventional method the drugs are accumulated near the surface of the body. In this study we intend to solve the problem by rotating the magnetic field. The drugs which were given to blood vessel are attracted to the inside wall of the on-axis blood vessel by the rotating magnetic force and thus the drugs are accumulated. On the other hand the accumulation is prevented in the off-axis blood vessel because the blood flow washes out the drugs. The feasibility of this technique was confirmed experimentally.
