MEDICAL SYSTEM AND METHOD FOR SETTING PROGRAMMABLE HEAT LIMITS
First Claim
1. A medical system, comprising:
- an implantable medical device;
an external device configured for transcutaneously coupling energy into the implantable medical device;
a sensor configured for measuring a parameter correlated to a temperature generated by the external device during coupling of the energy into the implantable medical device;
memory configured for storing a user programmable threshold; and
a processor configured for comparing the measured parameter to the user programmable threshold, and for controlling the temperature based on the comparison.

Abstract
An external charger transmits energy to charge an implanted medical device. A sensor measures a parameter that is correlated to a temperature that is adjacent to the external charger. This parameter is indicative of the temperature or an amount of heat that is generated during the charging of the implanted medical device by the external charger. The temperature is compared to a user programmable temperature threshold and based on the comparison, the charge rate or output power of the external charger or input power of the implanted medical device is adjusted to reduce the heat generated by the charging. The user programmable temperature threshold is set to an optimum charge rate whereby the temperature that is generated during charging of the implanted medical device by the external charger feels comfortable to the user.
