| Outline of Final Research Achievements |
The purpose of this study is drive of a stent motor. A general stent is inserted in the stenosis part of a blood vessel and is the medical device used for expansion of a blood vessel. However, there is a problem of restenosis that a plaque accumulates around the stent. So the stent motor is used for removal of the plaque.
And a design and a resonance experiment of the stent motor were carried out. The stent motor consists of two cylindrical receivers and one coil shaped stator. A drive source of the stent motor is vibration of the stator. When the ultrasonic is irradiated to the receiver, vibration of the stator occurs. First, the receiver which resonates was designed by numerical analysis. The receivers different in the size based on the analysis result were made. And the size which resonates certainly by the resonance experiment was specified. Next, the stent motor was designed. The stent motors were made and the size which resonates by the resonance experiment was specified.
