More Information
Summary:A system for use with a catheter having a distal structure including a plurality of electrodes includes a display and a processor. The processor is configured to ascertain a number of the electrodes contacting an ostium of a pulmonary vein, and in response to the number equaling or exceeding a predefined lower threshold, carry out an iterative process. The process includes, during each iteration of the process, in response to the number being less than a predefined higher threshold, computing an adjustment to a current pose of the distal structure, and displaying, on the display, a target-pose icon, which represents the distal structure, offset, per the adjustment, from a current-pose icon representing the distal structure at the current pose. Other examples are also described.
