External controller/charger system for an implantable medical device capable of automatically providing data telemetry through a charging coil during a charging session
First Claim
1. An external system for communicating with an implantable medical device, comprising:
- a data telemetry coil for communicating data to the implantable medical device;
a charging coil for providing power to charge a battery in the implantable medical device during a charging session, wherein the charging coil additionally communicates data to the implantable medical device during the charging session; and
data telemetry circuitry, wherein the data telemetry circuitry is coupled to the data telemetry coil not during the charging session to communicate the data to the implantable medical device, and is coupled to the charging coil during the charging session to communicate the data to the implantable medical device.

Abstract
An external controller/charger system for an implantable medical device is disclosed, in which the external controller/charger system provides automatic switching between telemetry and charging without any manual intervention by the patient. The external controller/charger system includes an external controller which houses a telemetry coil and an external charging coil coupled to the external controller. Normally, a charging session is carried out using the external charging coil, and a telemetry session is carried out using the telemetry coil. However, when a patient requests to carry out telemetry during a charging session, the external charging coil is used instead of the internal telemetry coil.
