1. An implantable neuro-stimulation device comprising:
a stimulator configured to control delivery of stimulation energy to neural tissue, the stimulator further configured to perform closed-loop control of the stimulation energy based on a feedback signal that is indicative of an evoked neural response;
a supervisor
connected to the feedback signal,
configured to detect malfunction of the stimulator based on the feedback signal;
connected to the stimulator to provide a status signal to the stimulator; and
configured to compare the feedback signal to a desired feedback value and to change the status signal based on the comparison to indicate malfunction upon detecting malfunction based on the feedback signal;
wherein the stimulator is configured to adjust the control of the stimulation energy by reducing the desired feedback value in response to the status signal from the supervisor indicating malfunction.
