Abstract

An exemplary includes acquiring an electroneurogram of the right carotid sinus nerve or the left carotid sinus nerve, analyzing the electroneurogram for at least one of chemosensory information and barosensory information and calling for one or more therapeutic actions based at least in part on the analyzing. Therapeutic actions may aim to treat conditions such as sleep apnea, an increase in metabolic demand, hypoglycemia, hypertension, renal failure, and corgestive heart failure. Other exemplary methods, devices, systems, etc., are also disclosed.

Claims

1. A method comprising:

administering insulin to a patient to lower blood glucose concentration;

acquiring an electroneurogram of carotid sinus nerve activity;

based at least in part on the administering and the acquiring, determining a relationship between blood glucose and carotid sinus nerve activity; and

sensing carotid sinus nerve activity and using the relationship to control delivery of a therapy wherein the therapy comprises increasing sympathetic activity responsive to sensing carotid sinus nerve activity indicative of a decrease in blood glucose.

2. The method of claim 1 wherein the therapy comprises a therapy to treat diabetes.

3. The method of claim 1 wherein the determining comprises filtering the electroneurogram to determine chemosensory information.

4. The method of claim 3 wherein the chemosensory information comprises blood glucose information.

5. The method of claim 1 wherein the determining comprises filtering the electroneurogram to determine barosensory information.

6. One or more computer-readable media comprising processor executable instructions for performing the acquiring, the determining, and the sensing and the using of the method of claim 1.

7. The method of claim 1 wherein the increasing sympathetic activity comprises cardiac pacing to increase heart rate.

8. The method of claim 1 further comprising acquiring patient activity information and using the information to, at least in part, control delivery of the therapy.

9. The method of claim 8 wherein the acquiring comprises acquiring information from an accelerometer.

10. The method of claim 1 further comprising assessing a glucometer reading based on the sensing carotid sinus nerve activity indicative of a decrease in blood glucose.

11. The method of claim 1 wherein the increasing sympathetic activity acts to hasten blood glucose release.

12. The method of claim 1 wherein the increasing sympathetic activity acts to hinder insulin release.

13. The method of claim 1 further comprising instructing an insulin pump to alter release of insulin.

14. The method of claim 1 further comprising activating or blocking one or more autonomic nerves related to pancreatic activity.
