Abstract:
(EN) Provided is a biopotential measurement device capable of accurately measuring the potential at an ablated site formed by ablating the surroundings of the interior wall surface of organs in ablation therapy or the like. Specifically, this biopotential measurement device is inserted into a body organ, and measures the potential at a predetermined site on the interior wall surface of the organ. The biopotential measurement device is provided with an insulating member and an electrode disposed in the insulating member. The outer peripheral surface of the insulating member is contacted with the interior wall surface of the organ, and the potential at the site in contact therewith is measured with the electrode.
(FR) L'invention concerne un dispositif de mesure de biopotentiel capable de mesurer avec précision le potentiel au niveau d'un site d'ablation formé par l'ablation de l'entourage de la surface de la paroi intérieure d'organes dans une thérapie d'ablation ou similaire. Spécifiquement, ce dispositif de mesure de biopotentiel est inséré dans un organe corporel, et mesure le potentiel au niveau d'un site prédéterminé sur la surface de la paroi intérieure de l'organe. Le dispositif de mesure de biopotentiel est pourvu d'un élément isolant et d'une électrode disposée dans l'élément isolant. La surface périphérique externe de l'élément isolant est mise en contact avec la surface de la paroi intérieure de l'organe, et le potentiel au niveau du site en contact avec celle-ci est mesuré avec l'électrode.
(JA) アブレーション治療等で、器官の内壁面の周囲を焼灼した際の焼灼部位の電位を、正確に計測することができる生体内電位計測器を提供する。具体的には、本発明の生体内電位計測器は、生体の器官内に挿入して、器官の内壁面における所定部位の電位を計測する生体内電位計測器であって、絶縁性部材と、絶縁性部材の中に配置された電極とを備え、絶縁性部材の外周面を、器官の内壁面に接触させた状態で、接触した部位の電位を、電極で計測する。
