An endoscope (1) supports an expansible stent (2) towards its patient end (12) between two video chips (13B and 14B) directed towards one another at a small angle. The video chips (13 and 14) are arranged to view both the inside of the trachea (40) or other body passage and opposite ends of the stent (2). A cables (15, 18) extends from the video chips (13B and 14B) to a monitor display (3), signals from the chips being supplied via the cable to provide representations of the field of view of both chips on the monitor. When the display images indicate that the (endoscope 1) is in the correct position, the stent (2) is expanded off and the display images are checked to ensure that the stent extends over the desired region of the passage (40). |
