    摘要： A porous electrode assembly includes a wall having a surface capable of contacting tissue. The wall peripherally surrounds an interior area. The assembly also includes a lumen to convey a medium containing ions into the interior area, as well as an electrically conductive element, which couples the medium within the interior area to a source of electrical energy. At least a portion of the wall comprises a porous material, which is sized to pass ions contained in the medium, to thereby enable ionic transport of electrical energy through the porous material to tissue contacting the wall. An imaging element is located in the interior area, which is coupled to a source of visualizing energy for visualizing tissue. At least a portion of the wall is generally transparent to the visualizing energy.

    摘要： A graphical user interface (GUI) is provided for assisting medical personnel in interpreting data collected by a multiple electrode catheter deployed within the body. The GUI generates and displays an image of the multiple electrode catheter. By manipulating appropriate controls, the medical personnel are able to change the orientation of the displayed image until it matches the orientation of the actual multiple electrode catheter as seen on a fluoroscope. Afterwards, the medical personnel can determine the relative position and orientation of the catheter by reference to the GUI generated image. To aid in interpreting data recovered by the catheter, the individual electrodes and splines are highlighted and labeled. Electrodes recovering particular types of physiological waveforms can be automatically identified and highlighted. Comments and anatomic landmarks can be inserted where desired to further assist in interpreting data. Views from various, virtual fluoroangles can be obtained, and various images can be recorded, stored and printed. The position of a roving electrode can also be indicated.

    摘要翻译： 提供图形用户界面（GUI），用于帮助医务人员解释由部署在身体内的多个电极导管收集的数据。 GUI生成并显示多个电极导管的图像。 通过操纵适当的控制，医务人员能够改变所显示的图像的方向，直到其与荧光镜上所见的实际多电极导管的取向相匹配。 之后，参照GUI生成的图像，医务人员可以确定导管的相对位置和取向。 为了帮助解释由导管回收的数据，单独的电极和花键被突出显示并标记。 恢复特定类型生理波形的电极可以自动识别和突出显示。 可以在需要时插入评论和解剖标志，以进一步帮助解释数据。 可以获得来自各种虚拟荧光的视图，并且可以记录，存储和打印各种图像。 还可以指出粗纱电极的位置。
