1. A system, comprising:
- an external device, comprisingcontrol circuitry for producing from first data a first signal modulated with pulse width modulation, and for producing from second data a second signal modulated with frequency modulation; and
a first antenna configured to wirelessly transmit the first modulated signal and the second modulated signal to the implantable medical device; and
an implantable medical device, comprising;
a first telemetry receiver in the implantable medical device for demodulating the first modulated signal to recover the first data; and
a second telemetry receiver in the implantable medical device for demodulating the second modulated signal to recover the second data.

Abstract
An exemplary system for communicating with an implantable stimulator includes a coil configured to transmit a signal modulated with either on-off keying (OOK) modulation or Frequency Shift Keying (FSK) modulation. The system further includes a first telemetry receiver in the implantable stimulator configured to receive the signal in accordance with the OOK modulation and a second telemetry receiver in the implantable stimulator configured to receive the signal in accordance with the FSK modulation.

12. A system, comprising:
-
an external device comprising a first coil coupled to control circuitry configured to transmit data in accordance with a first telemetry scheme and a second telemetry scheme; and an implantable medical device, comprising; a second coil, and telemetry circuitry coupled to the second coil for listening for and recovering the transmitted data whether transmitted in accordance with the first telemetry scheme or the second telemetry scheme, wherein the telemetry circuitry discontinues listening for the data transmitted in accordance with the first telemetry scheme when the implantable medical device while in a low power state, and wherein the telemetry circuitry continues listening for the data transmitted in accordance with the second telemetry scheme when the implantable medical device is in the power state. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
