Abstract
This disclosure relates to implantable neuro stimulation devices with a feedback loop to control an amount of energy delivered into a neural tissue based on a measured evoked neural response. Stimulation electrodes deliver stimulation energy to neural tissue. A microprocessor performs closed-loop control of the stimulation energy based on a feedback signal that is indicative of an evoked neural response. A supervisor is connected to the feedback signal and detects malfunction of the stimulator based on the feedback signal. The supervisor is also connected to the stimulator to provide a status signal to the stimulator and changes the status signal to indicate malfunction upon detecting malfunction based on the feedback signal. The microprocessor adjusts the control of the stimulation energy in response to the status signal from the supervisor indicating malfunction.
