Intra-gastric balloons have been and effective and non-invasive method for morbid obesity treating since it is proposed. However, traditional balloons lead to complications such as nausea and sickness caused by insertion and removal endoscopes. Despite free of endoscope-guide insertion and removal process, wireless controlled balloons still have to face the problem of energy shortage. This paper proposes a novel wireless controlled and powered endoscope capsule of edible size. The performance of wireless control and powering are tested respectively. In addition, in-vivo and in-vitro experiments are conducted for further evaluation and shows feasibility for treating morbid obesity. This study may contribute to the development of endoscopic devices and surgery as well.
