First Claim
Patent Images
1. A medical device adapted for implantation into a patient, comprising:
- a temperature sensor for measuring a temperature within the patient'"'"'s body;
sampling circuitry and an analog-to-digital converter for sampling and digitizing temperature measurement;
a controller for collecting and storing temperature measurements and for computing an average temperature measurement;
wherein the controller is configured to calibrate the temperature sensor by adjusting sensor measurements by an amount equal to the difference between the average temperature measurement and a nominal temperature assumed to be maintained by the patient'"'"'s body.
