PROBLEM TO BE SOLVED: To provide a neurostimulation electrode where blood clotting, thrombus formation, and the like are hard to occur due to its suspension.SOLUTION: A neurostimulation electrode 20 which is suspended in vivo and gives electric stimuli to the nerve includes: stimulating electrodes 33A, 33B for applying electric stimuli to the nerve: a suspension part 30 which has three or more energizing parts 31 that are elastically deformable, and holds the stimulating electrodes in the state that they are positioned and a lead part 21 for connecting a stimulus generator for generating electric stimuli and the suspension part. The energizing part is extended forward while being separated from an axis line of the lead part, and distal end parts of the respective energizing parts are placed at intervals from one another.COPYRIGHT: (C)2014,JPO&INPIT【課題】留置に伴う血液凝固や血栓形成等を生じにくい神経刺激電極を提供する。【解決手段】生体内に留置されて神経に電気刺激を行う神経刺激電極20は、神経に電気刺激を印加する刺激電極33A、33Bと、弾性変形可能な3つ以上の付勢部31を有し、刺激電極を位置決めされた状態で生体内に保持する留置部30と、電気刺激を発生する刺激発生装置と留置部とを接続するリード部21とを備え、付勢部は、リード部の軸線から離間しつつ前方に向かって延びており、それぞれの付勢部の先端部が互いに間隔をあけて配置されていることを特徴とする。【選択図】図2
