Abstract
The apparatus is intended to monitor operation of an artificial internal organ, such as an auxiliary heart, which is to be attached to the patient's body on the outer side. An optical fiber for image pick-up and another optical fiber for illumination are mounted to the artificial internal organ, and a video camera, light source for illumination, control switches, monitor television unit, etc. are disposed in a position remote from the artificial internal organ. For the purpose of enlarging the monitoring range and providing illumination of high efficiency, a mirror is mounted in the artificial internal organ. An optical axis of the optical fiber for image pick-up is arranged to be opposite or perpendicular to that of the optical fiber for illumination.
