Interactive systems and methods for controlling the use of diagnostic or therapeutic instruments in interior body regions

A system comprising:

• an electrode structure which, in use, is deployed in contact with heart tissue;
• a controller coupled to the electrode structure operating to establish an operating condition to perform a diagnostic or therapeutic procedure, and
• an interface comprising
• a display screen, and
• an interface manager coupled to controller and the display screen, wherein the interface manager performs a first function to generate a first display comprising an image of the electrode structure at least partially while performing the procedure, a second function to generate a second display comprising one or more data fields reflecting the operating condition of the controller, and a third function to enable selection of the first display or the second display for viewing on the display screen.

A method for examining myocardial tissue comprising the steps of

• deploying an electrode structure in contact with myocardial tissue,
• generating a first display comprising an image of the electrode structure,
• generating a second display comprising one or more data fields reflecting an operating condition of the electrode structure, and
• causing the electrode structure to either pace myocardial tissue, or record electric events in myocardial tissue, or both, while selecting the first display or the second display for viewing on a display screen.
