DUAL PROPHYLACTIC AND ABORTIVE ELECTRICAL STIMULATION
First Claim
Patent Images
1. A method comprising:
- delivering prophylactic electrical stimulation to a cranial nerve based on a first range of stimulation thresholds associated with 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 based on a second range of stimulation thresholds associated with 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.

5. The method of claim 5, wherein the second range of stimulation thresholds comprises a range from a second low stimulation threshold to a second high stimulation threshold, and wherein the second low stimulation threshold comprises at least one of a second perception or a second parasthesia threshold and the second high stimulation threshold comprises at least one of a second muscle recruitment, a second discomfort, or a second pain threshold.

11. 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 based on a first range of stimulation thresholds associated with patient perception in the absence of any symptoms of a chronic condition and to deliver abortive electrical stimulation to the cranial nerve based on a second range of stimulation thresholds associated with 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 (12, 13, 14, 15, 16, 17, 18, 19, 21, 22)
