Intravascular Stent Motor

Abstract:

We have developed a movable stent motor in the blood vessel by applying the technique of the ultrasonic motor. We have also designed a stent motor which consists of two parts; a stator part and receiver part. The receiver unit obtains the ultrasonic wave from outside and the stator generates a driving force. The stator is the coil shape and it can move smoothly in intravascular. Adding that, we have designed the horn to provide ultrasonic energy to it from outside of human body. We have made experiments by the horn and the stent motor and we have succeeded in driving the stent motor in the water back and forth.
