Development of Stent Motor

Shigeki Toyama and Uichi Nishizawa
Abstract—The purpose of this study is to develop a stent motor applicable for medical blood vessel treatment. The stent motor is a movable stent and it has functions of removing plaque and expanding blood vessels. It consists of two parts; ultrasonic receivers and vibration transmitting coil (stator). In this study, the authors have focused in the vibration analysis of the receiver. In the design stage, the authors have evaluated resonant phenomenon using finite element method. When applying it in water, the resonant frequency in the air is shifted due to mass effect of water around the receiver. Frequency response analysis of the receiver shows that extremely high precision of dimensions is required because the resonant frequency in water depends not only size but also the amplitude of the vibration. It is very difficult to design an optimal receivers resonating in water. In order to solve this problem, the authors have tried a new receiver with wide plate receiving ultrasound effectively and requiring no resonant. The authors have succeeded in driving this type of motor in water.

Index Terms—cUltrasonic motor, piezoelectric actuator, waterproof actuator and stent.
