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.
Claims41
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 communication scheme, and a second telemetry receiver for receiving data over a second telemetry link in accordance with a second communication scheme different from the first communication scheme.
An external device configured to communicate with an implantable stimulator, the device comprising:
- a coil configured to transmit a data signal in accordance with a first telemetry scheme or a second telemetry scheme.
A system, comprising:
- an external device, comprising
- control 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 or 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.
A method for receiving communications in an implantable medical device, comprising:
- receiving a first modulated signal from an external device, wherein the first modulated signal comprises first data modulated with pulse width modulation;
- receiving a second modulated signal from an external device, wherein the second modulated signal comprises second data modulated with frequency modulation;
- using a first telemetry receiver in the implantable medical device to demodulate the received first modulated signal to recover the first data;
- and
- using a second telemetry receiver in the implantable medical device to demodulate the received second modulated signal to recover the second data.
A method for receiving communications in an implantable medical device, comprising:
- receiving a second modulated signal from an external device at a second telemetry receiver in the implantable medical device, wherein the second modulated signal comprises a second telemetry scheme;
- when reception of the second modulated signal is disabled, using a first telemetry receiver in the implantable medical device to listen for and demodulate a received first modulated signal to recover first data, wherein the first modulated signal comprises a first telemetry scheme;
- and
- using the recovered first data to enable the reception of the previously disabled second modulated signal.
