Dual prophylactic and abortive electrical stimulation
First Claim
Patent Images
1. 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.

13. 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. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
