ABSTRACT:
A body-insertable apparatus which can make the volume smaller by simplifying a mechanism taking in or throwing out predetermined fluid is realized. The body-insertable apparatus has a configuration having, in a housing, a balloon member, a communication adjusting mechanism, a control circuit, and a power source part and forms a storage chamber by the balloon member and an outer circumferential member (sheet holding substrate and part of the housing) covering the outer surface of the balloon member. In the body-insertable apparatus, a first communication pipe communicated with the inner space of the balloon member and a second communication pipe communicated with the outer space are formed. The communication adjusting mechanism communicates the first communication pipe with the second communication pipe based on an electric current output from the control circuit. The inner space of the balloon member is communicated with the outside of the body-insertable apparatus. The outside fluid is flowed into the storage chamber via an inlet with the contracting operation of the balloon member.
