External charger usable with an implantable medical device having a programmable or time-varying temperature set point
First Claim
1. An external charger for producing energy to power or charge an implantable medical device during a charging session, comprising:
- temperature sensing circuitry configured to determine a temperature of the external charger during the charging session;
a user interface configured to provide a plurality of options selectable by a user, wherein each user selection provides at least one temperature set point; and
control circuitry configured to control the energy produced to power or charge the implantable medical device in accordance with the provided at least one temperature set point and the determined temperature.

Abstract
An improved external charger for charging the battery within or providing power to an implantable medical device is disclosed. The improved external charger includes circuitry for detecting the temperature of the external charger and for controlling charging to prevent exceeding a maximum temperature. The external charger in some embodiments includes a user interface for allowing a patient to set the external charger'"'"'s maximum temperature. The user interface can be used to select either constant maximum temperatures, or can allow the user to choose from a number of stored charging programs, which programs can control the maximum temperature to vary over time. Alternatively, a charging program in the external charger can vary the maximum temperature set point automatically. By controlling the maximum temperature of the external charger during charging in these manners, the time needed to charge can be minimized while still ensuring a temperature that is comfortable for that patient.
