The theme of the invention is to provide catheter localization using fiber optic shape sensing combined with current location. An apparatus includes a shaft, a flexible distal-end assembly, two or more sensing-electrodes, and a fiber-optic shape sensor. The shaft is configured for insertion into a body of a patient. The flexible distal-end assembly is fitted at a distal end of the shaft. The two or more sensing-electrodes are disposed over the distal-end assembly and are configured to generate signals indicative of positions of the sensing-electrodes in the body. The fiber-optic shape sensor is coupled to a portion of the distal-end assembly, wherein the two or more sensing electrodes have a-priori known distances from a known location over the fiber-optic shape sensor, and wherein the fiber-optic shape sensor is configured to provide an indication of a spatial deformation of the flexible distal end assembly. 本发明题为"使用光纤形状感测结合当前位置的导管定位"。本发明提供了一种设备，该设备包括轴、柔性远端组件、两个或多个感测电极和光纤形状传感器。轴被配置为用于插入患者的身体中。柔性远端组件装配在轴的远端处。
