    • A catheter device for creating linear lesions in endocardial tissue or other body tissue is described. The catheter includes an inner shaft telescopically received within an outer shaft. The inner shaft has one or more spaced apart electrodes along its distal section. The outer shaft member includes a fluid permeable window positionable to selectively overlay some or all of the electrodes when the relative positioning of the inner and outer shaft members is adjusted. During use, the window is positioned adjacent to the body tissue which is to be ablated and at least a portion of the electrodes are exposed through the window. RF energy is delivered to the electrodes while saline or other conductive fluid is simultaneously delivered through the infusion tube. The conductive fluid passes into contact with the electrodes, and through the window into contact with the body tissue, thereby improving the coupling of the RF energy from the electrodes to the tissue and improving the efficiency of the ablation of the tissue.
    • 描述了用于在心内膜组织或其他身体组织中产生线性损伤的导管装置。 导管包括可伸缩地容纳在外轴内的内轴。 内轴沿其远端部分具有一个或多个间隔开的电极。 外轴构件包括可流体渗透的窗口,其可调节内和外轴构件的相对定位时可选择地覆盖部分或全部电极。 在使用期间,窗口被定位成邻近待烧蚀的身体组织,并且至少一部分电极通过窗户暴露。 RF能量被传送到电极,而盐水或其它导电流体同时通过输液管输送。 导电流体与电极接触并且通过窗口与身体组织接触,从而改善从电极到组织的RF能量的耦合并提高组织消融的效率。

    • An endocardial mapping catheter for introduction into a chamber of a heart formed by a wall. The flexible elongate tubular member has proximal and distal extremities and extends along a longitudinal axis. A plurality of longitudinally-extending spaced-apart members are carried by the distal extremity of the flexible elongate tubular member and have proximal extremities and interconnected distal extremities. Certain of the plurality of longitudinally-extending members are arms of a basket-like assembly and are movable between contracted positions and expanded positions in which the arms bow outwardly from the longitudinal axis. A plurality of longitudinally spaced-apart electrodes are carried by each of the arms. Electrical conductors extend through the flexible elongate tubular member and are connected to the electrodes for performing electrical functions with respect to the electrodes. At least one additional electrode is slidably mounted on one of the longitudinally-extending members.
    • 用于引入由壁形成的心脏室的心内膜定位导管。 柔性细长管状构件具有近端和远端,并且沿着纵向轴线延伸。 多个纵向延伸的间隔开的构件由柔性细长管状构件的远端承载并且具有近端和相互连接的远端。 多个纵向延伸的构件中的某些是篮状组件的臂,并且可以在收缩位置和扩展位置之间移动,在该位置中臂从纵向轴线向外伸出。 多个纵向间隔开的电极由每个臂承载。 电导体延伸穿过柔性细长管状构件并且连接到电极以相对于电极执行电功能。 至少一个附加电极可滑动地安装在一个纵向延伸部件上。
