    • A catheter is designed with a virtual electrode structure for creating a linear lesion. The catheter includes a sensor array that measures temperatures of adjacent tissue along the length of the virtual electrode section. The sensors in the sensor array include a conductive material that is substantially coated with an electrically and thermally insulating material. An aperture is formed in the insulating coating to expose an area of the conductive material. Leads are coupled with each sensor and are connected at their opposite, proximal ends with a discrimination circuit. The circuit processes the signals induced in the sensors to output a single temperature measurement, for example, the highest temperature, the lowest temperature, or the average temperature. The sensors also measure cardiac electrical activity and the leads are further connected to an electrocardiograph monitor to determine the efficacy of treatment.
    • 导管设计有用于产生线性损伤的虚拟电极结构。 导管包括传感器阵列,其测量沿着虚拟电极部分的长度的相邻组织的温度。 传感器阵列中的传感器包括基本上涂覆有电绝热材料的导电材料。 在绝缘涂层中形成孔以暴露导电材料的区域。 引线与每个传感器耦合,并且在其相对的近端处与鉴别电路连接。 电路处理在传感器中感应的信号,以输出单个温度测量,例如最高温度,最低温度或平均温度。 传感器还测量心脏电活动,并且引线进一步连接到心电图仪监测器以确定治疗的功效。
