Driver circuitry switchable between energy transfer and telemetry for an implantable medical device
First Claim
1. An external device for an implantable medical device having therapeutic componentry, a secondary coil operatively coupled to said therapeutic componentry and an internal telemetry coil, comprising:
- a primary coil capable of inductively energizing said secondary coil when externally placed in proximity of said secondary coil;
an external telemetry coil capable of communicating with said internal telemetry coil; and
driver circuitry selectively operatively coupled to said primary coil and to said external telemetry coil;
said driver circuitry being switchable between (1) driving said primary coil for inductively energizing said secondary coil and (2) driving said external telemetry coil for communicating with said internal telemetry coil.

Abstract
An external device, charge, system and method for an implantable medical device having therapeutic componentry, a secondary coil operatively coupled to the therapeutic componentry and an internal telemetry coil. A primary coil is capable of inductively energizing the secondary coil when externally placed in proximity of the secondary coil. An external telemetry coil is capable of communicating with the internal telemetry coil. Driver circuitry is selectively operatively coupled to the primary coil and to the external telemetry coil. The driver circuitry is switchable between (1) driving the primary coil for inductively energizing the secondary coil and (2) driving the external telemetry coil for communicating with the internal telemetry coil.
