| Research Abstract |
Palliative biliary drainage using a metallic stent is performed for biliary obstruction by unresectable biliary carcinoma. The most important problem of biliary stenting therapy is re-obstruction due to tumor ingrowth. In this study, we used a detached temperature sensor with a magnetic-wave device. A titanium alloy stent was able to generate enough temperature when it was excited by 900kHz magnetic-wave device, however, the experiment could not reach to the stage to test connected sensor and magnetic-wave device in vivo.
