PROBLEM TO BE SOLVED: To provide an electrode system capable of being securely and easily attached to linear tissue of a living body.SOLUTION: The electrode system 1 includes an electrode part 2 at least part of which can change the shape from a curved shape curved to be wound around prescribed linear tissue N or flat shape to the other shape, and a treatment instrument 3 for changing the shape of the at least part of the electrode part from the curved shape or flat shape to the other shape. The electrode part includes a sheet-shaped insulation member 9 made of an elastic material, and an electrode 10 disposed on one surface 9a on the inner side of a curve when the insulation member 9 is in the curved shape for applying prescribed voltage.COPYRIGHT: (C)2011,JPO&INPIT【課題】生体の線状組織に確実かつ容易に取り付け可能な電極システムを提供する。【解決手段】電極システム1は、所定の線状組織Nに巻きつくように湾曲した湾曲形状および平坦な平坦形状のいずれか一方から他方に少なくとも一部が形状を切り替え可能な電極部2と、電極部の少なくとも一部の形状を湾曲形状および平坦形状のいずれか一方から他方に切り替える処置具3とを備え、電極部は、弾性材料でシート状に形成された絶縁部材9と、絶縁部材が湾曲形状であるときに湾曲の内側の面となる一方の面9aに設けられ所定の電圧を印加可能な電極10とを有する。【選択図】図11
