Abstract

A display is located on an interventional device insertible into a body. More specifically, the display is located on a distal end of the device and is coupled to a sensing system. The sensing system senses a bodily condition. The display receives the sensed bodily condition and displays a signal indicative of the bodily condition within a pre-existing field of view.
