Abstract
An electrode coupling output system provides indication to the physician, via electrode guidance instrumentation, concerning the electrical coupling of an electrode, such as an ablative or mapping electrode, with a patient. The output can be provided to the physician via an output device incorporated into the handle set of the electrode catheter. For example, a visual, audio or mechanical output can be provided via the handle set. Additionally or alternatively, the output can be provided to the physician via a navigation system. The indication may be provided by changing the color or other display characteristics of the electrode on the navigation system display or by way of providing a waveform indicating the electrode coupling. In this manner, electrode coupling information is provided to a physician in a manner that minimizes physician distraction.
