Abstract

Methods of detecting an error associated with an implantable device include powering up the implantable device with an external device, disabling a back-telemetry transmitter within the implanted device after the implanted device is powered up, detecting an error with the implanted device, generating a fault signal corresponding to the error with the implanted device, turning on the back-telemetry transmitter after the fault signal has been generated, and transmitting the fault signal to the external device with the back-telemetry transmitter.

Claims

1. A method, comprising:

powering up a device implanted within a patient with an external device;

transmitting a fault signal with a back-telemetry signal within said implanted device to said external device in response to being powered up by said external device, wherein the fault signal is for the external device to verify a successful power up of the implanted device;

disabling said back-telemetry transmitter within said implanted device after said implanted device is powered up;

detecting an error with said implanted device;

generating an additional fault signal corresponding to said error with said implanted device;

turning on said back-telemetry transmitter after said fault signal has been generated; and

transmitting said additional fault signal to said external device with said back-telemetry transmitter.

2. The method of claim 1, further comprising using said additional fault signal to remedy said error.

3. The method of claim 1, wherein said error comprises at least one or more of an error in one or more voltage levels, an error in data transmitted from the external device, a power reset of said implantable device, and a malfunction of one or more components within said implantable device.

4. A method comprising:

powering up a device implanted within a patient with an external device;

transmitting, by the implanted device, a fault signal with a back-telemetry transmitter to the external device in response to being powered up by the external device, wherein the fault signal is for the external device to verify a successful power up of the implanted device;

verifying, by the external device, a functionality of the implanted device by detecting the fault signal;

disabling, by the external device, the back-telemetry transmitter of the implanted device after the functionality of the implanted device is verified;

detecting, by the implanted device, an error associated with the implanted device while the back-telemetry transmitter is disabled;

generating, by the implanted device, another fault signal when the error is detected;

enabling, by the implanted device, the disabled back-telemetry transmitter when the error is detected; and

transmitting, by the implanted device, the another fault signal with the enabled back-telemetry transmitter to the external device; and

disabling, by the implanted device, the back-telemetry transmitter after the another fault signal is received by the external device.

5. The method of claim 4, further comprising:

detecting, by the external device, one or more fault codes contained within the another fault signal; and

using, by the external device, the one or more fault codes to remedy the error.

6. The method of claim 5, further comprising remedying, by the external device, the error by rebooting the implanted device.

7. The method of claim 4, further comprising periodically turning on, by the external device, a receiver of the external device to detect a presence of the another fault signal.

8. The method of claim 4, wherein the error comprises at least one or more of an error in one or more voltage levels, an error in data transmitted from the external device, a power reset of the implanted device, and a malfunction of one or more components within the implanted device.

9. The method of claim 4, wherein the implanted device comprises an implantable stimulator.

10. The method of claim 9, further comprising automatically ceasing, by the implantable stimulator, stimulation when the error is detected.

11. The method of claim 4, wherein the implanted device comprises an implantable cochlear stimulator and wherein the external device comprises a speech processor.

12. A method comprising:

transmitting, by a back-telemetry transmitter included in a device implanted within a patient, a fault signal to an external device via a back-telemetry link, wherein the fault signal is transmitted when the external device powers up the implanted device and is for the external device to verify a successful power up of the implanted device;

disabling, by a status generator included in the implanted device, the back-telemetry transmitter after the fault signal is transmitted to the external device;

detecting, by the status generator, an error associated with the implanted device while the back-telemetry transmitter is disabled;

generating, by the status generator, another fault signal when the error is detected;

enabling, by the status generator, the disabled back-telemetry transmitter when the error is detected;

causing, by the status generator, the enabled back-telemetry transmitter to transmit the another fault signal to the external device; and

disabling, by the status generator, the back-telemetry transmitter after the another fault signal is received by the external device.

13. The method of claim 12, further comprising receiving, by a forward-telemetry receiver included in the implanted device, one or more signals configured to remedy the error from the external device.

14. The method of claim 13, wherein the one or more signals are configured to remedy the error by rebooting the implanted device.

15. The method of claim 12, wherein the error comprises at least one or more of an error in one or more voltage levels, an error in data transmitted from the external device, a power reset of the implanted device, and a malfunction of one or more components within the implanted device.
