Summary:To provide a medical catheter.SOLUTION: A medical catheter has an inflatable balloon assembly on its distal portion and a plurality of ablation electrodes disposed on the surface of the balloon assembly. Conductors extending through a shaft supply the ablation electrodes with electrical power when connected to a power source. A plurality of thermistors on the balloon assembly are connected to the conductors to form a resistive network, and a plurality of access points on the conductors are provided for obtaining electrical measurements and analyzing the measurements to determine respective resistances of the thermistors.SELECTED DRAWING: Figure 1 【課題】 医療用カテーテルを提供すること。【解決手段】 医療用カテーテルは、その遠位部分の膨張可能なバルーンアセンブリと、バルーンアセンブリの表面に配置された複数のアブレーション電極と、を有する。シャフトを通って延びる導体は、電源に接続される際にアブレーション電極に電力を供給する。バルーンアセンブリ上の複数のサーミスタが導体に接続されて抵抗ネットワークを形成し、導体上の複数のアクセスポイントが、電気的測定値を得て、測定値を解析して、サーミスタのそれぞれの抵抗を決定するために提供される。【選択図】 図１
