GLYCEMIC CONTROL MONITORING USING IMPLANTABLE MEDICAL DEVICE
First Claim
1. An apparatus for monitoring a patient'"'"'s blood glucose level, the apparatus comprising:
- (i) an implantable medical device having a controller;
(ii) an implantable heart sounds sensor configured to transmit signals to the controller of the implantable medical device; and
(iii) wherein the controller is configured to determine if a patient is hypoglycemic or hyperglycemic based on the signals from the heart sounds sensor.

Abstract
An apparatus for monitoring a patient'"'"'s blood glucose level. The apparatus includes an implantable medical device having a controller and an implantable heart sounds sensor configured to transmit signals to the controller of the implantable medical device. The controller is configured to determine if a patient is hypoglycemic or hyperglycemic based on the signals from the heart sounds sensor. A method is also disclosed that includes sensing the patient'"'"'s heart sounds, determining the amplitude of the S2 heart sound, determining the length of the interval from the S1 heart sound to the S2max heart sound, determining the length of the interval from the S1 heart sound to the S2end heart sound, and determining the patient'"'"'s blood glucose status based on the patient'"'"'s heart sounds.
