Abstract
Prophylactic stimulation and abortive electrical stimulation are delivered to a cranial nerve, including, e.g. an occipital or trigeminal nerve to treat symptoms of various conditions, including, e.g. occipital neuralgia or migraines.
Claims27
A method comprising:
- delivering prophylactic electrical stimulation to a cranial nerve at a first stimulation intensity within a first range of stimulation intensity thresholds determined based on patient perception in the absence of any symptoms of a chronic condition, wherein the prophylactic stimulation is configured to inhibit onset of a symptom of the chronic condition;
- and
- delivering abortive electrical stimulation to the cranial nerve at a second stimulation intensity within a second range of stimulation intensity thresholds determined based on patient perception while a symptom of the chronic condition is occurring, wherein the abortive stimulation is configured to reduce an effect of a symptom of the chronic condition.
A system comprising:
- an implantable electrical stimulation generator;
- and
- a processor configured to control the stimulation generator to deliver prophylactic electrical stimulation to a cranial nerve at a first stimulation intensity within a first range of stimulation intensity thresholds determined based on patient perception in the absence of any symptoms of a chronic condition, and to deliver abortive electrical stimulation to the cranial nerve at a second stimulation intensity within a second range of stimulation intensity thresholds based on patient perception while a symptom of the chronic condition is occurring,
- wherein the prophylactic stimulation is configured to inhibit onset of a symptom of the chronic condition, and
- wherein the abortive stimulation is configured to reduce an effect of a symptom of the chronic condition.
2 more elements
A computer-readable storage medium comprising instructions for causing a programmable processor to:
- deliver prophylactic electrical stimulation to a cranial nerve at a first stimulation intensity within a first range of stimulation intensity thresholds determined based on patient perception in the absence of any symptoms of a chronic condition, wherein the prophylactic stimulation is configured to inhibit onset of a symptom of the chronic condition;
- and
- deliver abortive electrical stimulation to the cranial nerve at a second stimulation intensity within a second range of stimulation intensity thresholds determined based on patient perception while a symptom of the chronic condition is occurring, wherein the abortive stimulation is configured to reduce an effect of a symptom of the chronic condition.
