PROBLEM TO BE SOLVED: To downsize an external feeder for supplying power to an electrostimulator.SOLUTION: The electrostimulator has a body block including: a stimulation circuit block having a stimulation electrode for stimulating nerves or the like, and an electronic circuit for applying stimulation signals to the stimulation electrode and a support for holding an implantation position inside the living body of the stimulation electrode. Then, the electrostimulator has a fixture which includes a coil part for performing power supply and/or communication to/with the electronic circuit correspondingly to electromagnetic waves oscillated from an external device and is provided to the proximal end part of the body block. The electronic circuit and the coil part are connected by a conductor, and at least a part of the conductor is formed into a spiral shape so as to be expanded and contracted.COPYRIGHT: (C)2011,JPO&INPIT【課題】電気刺激装置に給電を行うための外部の給電装置を小型化する。【解決手段】神経等を刺激する刺激電極と、刺激電極に刺激信号を印加する電子回路とを有する刺激回路ブロックと、刺激電極の生体内の植え込み位置を保持する支持体とを含む本体ブロックを備える。そして、外部装置から発振された電磁波に応じて給電および/または通信を電子回路に行うコイル部を含み、本体ブロックの基端部に設けられた固定具を備える。電子回路とコイル部が導線で接続されており、該導線の少なくとも一部が伸縮可能にらせん状に形成されている。【選択図】図1
