PROBLEM TO BE SOLVED: To provide a multi-channel electrode which can be anchored without causing damage to the tissue.SOLUTION: This electrode bundle for implantation in a soft tissue comprises two or more electrodes aligned in parallel. Each electrode comprises an electrode member 3, an anchoring member 5 joined to the electrode member at a portion intermediate between a front end part 4 and a rear end part thereof and a means 7 for bundling the electrodes disposed between the anchoring member and the rear end part of the electrode. The anchoring member forms an angle α ranging from 0° to 60° together with the electrode member and extends in the direction of the rear end part thereof. There are also provided a stack of electrode bundles, methods for inserting the electrode bundle and the stack into the soft tissue, and their use.COPYRIGHT: (C)2013,JPO&INPIT【課題】組織に損傷を引き起こすこと無く、固定することができる多重チャンネル電極を提供する【解決手段】軟組織への埋め込み用の電極束は平行に配列された二つ以上の電極を含む。各電極は電極部材3、その前端部4及び後端部の中間の部分で電極部材に結合されている固定部材5、及び固定部材と電極の後端部との間に配置された電極を束ねる手段7を含む。固定部材は電極部材と共に0°から60°のα角度を形成し、その後端部方向に延びている。他に、電極束の積み重ね物、電極束及び積み重ね物の軟組織への挿入方法、及びそれらの使用も開示される。【選択図】図5
