摘要:
An interface for performing a diagnostic or therapeutic procedure on heart tissue with an electrode structure includes a controller which operates to establish an operating condition for the electrode structure, a processing unit coupled to the controller, a memory storage device including process software adapted to be executed by the processing unit and a graphical user interface including a display screen coupled to the processing unit. The process software performs a first control application and a second control application, each control application prescribing procedures for carrying out a given task using the electrode structure, at least one of the control applications prescribing a clinical procedure affecting heart tissue. The process software further performs a first function to create on the display screen separate first and second display regions, a second function to show in the first display region a selection menu display comprising a first field for selecting the first control application for execution and a second field for selecting the second control application for execution, and a third function to show in the second display region a first graphical display during execution of the first control application and a second graphical display during execution of the second control application.

A sleeve assembly for use in the transition region of a catheter between a relatively stiff catheter body and a less stiff distal catheter region mediates the difference in stiffness between these two catheter regions.

Systems and methods for locating an operative element within an interior body space use a locating probe, which includes at least one transmitting element to transmit an electric waveform output within at least a portion of the space. The systems and methods also use a sensing element, which is adapted to be carried by the operative element to sense a local electric waveform within the space. A processing element coupled to the sensing element generates a processed output that locates the sensing element relative to the locating probe based, at least in part, upon a differential comparison of the waveform output and the sensed local waveform.

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 fluoro angles can be obtained, and various images can be recorded, stored and printed. The position of a roving electrode can also be indicated.
摘要:
A catheter tube carries an imaging element for visualizing tissue. The catheter tube also carries a support structure, which extends beyond the imaging element for contacting surrounding tissue away from the imaging element. The support element stabilizes the imaging element, while the imaging element visualizes tissue in the interior body region. The support structure also carries a diagnostic or therapeutic component to contact surrounding tissue.
