Research Abstract

We have developed coil type ultrasonic motor for medical use especially for IVUS (Intravascular Ultrasound). IVUS is a useful medical device to observe the thrombus in blood vessels, and such a micro motor less than 1.0mm in outer diameter is desired to apply IVUS in narrow brain vessels. In our previous works, ultrasonic motor consisting of a wire coil type stator, a waveguide, a cylindrical rotor, an ultrasonic vibrator has been developed.
