摘要： An encapsulated medical device system according to an embodiment of the present invention includes a selector between a receiving device and a plurality of receiving antennas having their respective directionalities. The system selects and disconnects any receiving antenna subjected to the effect of a magnetic field used to guide a capsule endoscope, and captures information about the inside of a body from the appropriate receiving antenna thus selected. The system prevents an overload current caused by induced voltage from being applied to the receiving device. The system includes the function of preventing the overload current, caused by induced voltage arising from a sudden movement of the capsule endoscope or sudden change in magnetic field gradient, from being applied to a transmission circuit of the capsule endoscope and a receiving device.
