Patent Images
1. A medical device adapted for implantation into a patient, comprising:
- an implantable housing;
sensing circuitry for sensing cardiac activity;
pulse generation circuitry for delivering pacing pulses to the patient'"'"'s heart;
a temperature sensor for measuring a temperature within the patient'"'"'s body and generating temperature signals in accordance therewith;
sampling circuitry and an analog-to-digital converter for producing digitized samples of a signal received from the temperature sensor;
a controller interfaced to the pulse generation and sensing circuitry and configured for processing and storing temperature data derived from the temperature signals;
wherein the sensing circuitry, pulse generation circuitry, temperature sensor, sampling circuitry, and controller are contained within the implantable housing; and
,wherein the controller is programmed to monitor temperatures before implantation of the device and to set an alarm flag for temperature limits.
