Systems and methods for communicating with an implantable stimulator

摘要

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.

1. An implantable medical device, comprising:
a coil; and telemetry circuitry coupled to the coil for allowing data-containing signals to be received from at least one external device, the telemetry circuitry comprising a first telemetry receiver for receiving data over a first telemetry link in accordance with a first frequency modulation telemetry scheme, and a second telemetry receiver for receiving data over a second telemetry link in accordance with a second On-Off-Keying telemetry scheme, wherein at least the second telemetry receiver is configured to receive calibration data used to synchronize a reference clock signal with a frequency used to transmit or receive data using the first frequency modulated telemetry scheme.
