    摘要: A catheter assembly comprising a elongated, flexible support structure having an axis. The assembly also includes an elongated porous electrode assembly carried by the support structure along the axis for contact with tissue. The elongated porous electrode assembly comprises a wall having an exterior peripherally surrounding an interior area, a lumen to convey a medium containing ions into the interior area, and an element coupling the medium within the interior area to a source of electrical energy. At least a portion of the wall comprising a porous material is sized to allow passage of ions contained in the medium to thereby enable ionic transport of electrical energy through the porous material to the exterior of the wall to form a continuous elongated lesion pattern in tissue contacted by the wall. The support structure can have a curvilinear geometry, e.g., a loop shape, and the elongated porous electrode assembly conforms to the curvilinear geometry.

    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.
