Patent ID: 8391972

Claim:
A neural stimulation system, comprising: a stimulation output circuit including at least one stimulation channel configured to deliver neural stimulation pulses; a stimulation controller coupled to the stimulation output circuit, the stimulation controller configured to control the delivery of the neural stimulation pulses using a plurality of stimulation parameters; and a safety controller coupled to the stimulation controller, the safety controller including: a safety-control event detection module including an unintended effect detection module and an energy detection module, the unintended effect detection module configured to detect an unintended effect associated with the delivery of the neural stimulation pulses, the energy detection module configured to detect a stimulation energy being an energy of one or more of the neural stimulation pulses, the safety-control event detection module configured to indicate a detection of a safety-control event in response to a detection of the unintended effect and in response to the stimulation energy exceeding a predetermined threshold energy; and a safety response module configured to adjust one or more parameters of the plurality of stimulation parameters in response to the detection of the safety-control event being indicated.
