<p><P>PROBLEM TO BE SOLVED: To provide a vision regeneration assisting apparatus which continues operation of an intracorporeal device in case of failure. <P>SOLUTION: The vision regeneration assisting apparatus is equipped with an extracorporeal device having a transmitting mean of stimulation data and electric power and the intracorporeal device having a receiving means of the stimulation data and the electric power and outputting stimulation pulses from an electrode based on the stimulation data and the electric power. The intracorporeal device includes a first unit for converting the stimulation data and the electric power to a predetermined signal, a second control unit which extracts the stimulation data from the signal and outputs stimulation pulses from the electrode, and conductors for connecting the first and second units. The first unit is equipped with a conductor selecting means for simultaneously using one line of the conductors as a monitor line for detecting the failure and two lines out of the other conductors as power supply lines and a conductor failure determining means for determining whether three selected conductors are simultaneously used as the monitor line and the power supply lines, and the second unit connects the conductors in parallel through a rectifying device. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
