Active telemetry response for hearing implants
First Claim
1. An implantable processor arrangement for an active implantable medical device (AIMD) system implanted under the skin of a patient, the arrangement comprising:
- an implantable communications coil arrangement configured for transdermal transfer of an implant communications signal; and
an implantable processor coupled to and controlling the implantable communications coil arrangement so as to operate in two different communications modes;
i. a normal operation mode wherein the processor configures the communications coil arrangement for peridermal communication with an external communications coil placed on the skin of the patient immediately over the implantable communications coil arrangement using load modulation of the communications coil arrangement, andii. a long range telemetry mode wherein the processor configures the communications coil arrangement for extradermal communication with an external telemetry coil located distant from the skin of the patient immediately over the implantable communications coil arrangement without using load modulation of the communications coil arrangement.

Abstract
An implantable processor arrangement is described for an active implantable medical device (AIMD) system implanted under the skin of a patient. An implantable communications coil arrangement is configured for transdermal transfer of an implant communications signal. An implantable processor is coupled to and controls the implantable communications coil arrangement so as to operate in two different communications modes. In a normal operation mode, the processor configures the communications coil arrangement for peridermal communication with an external communications coil placed on the skin of the patient immediately over the implantable communications coil arrangement. In a long range telemetry mode, the processor configures the communications coil arrangement for extradermal communication with an external telemetry coil located distant from the skin of the patient immediately over the implantable communications coil arrangement.

7. A fitting system for an active implantable medical device (AIMD) system, the fitting system comprising:
-
an external fitting module configured to perform a patient fitting process that adjusts an implanted AIMD processor to reflect patient-specific performance characteristics, wherein the AIMD processor has; i. a normal operation mode that configures an implanted communications coil arrangement for peridermal communication of an implant communications signal with an external communications coil placed on the skin of the implanted patient immediately over the implanted communications coil arrangement using load modulation of the communications coil arrangement for normal operation of the AIMD system, and ii. a long range telemetry mode that configures the implanted communications coil arrangement for extradermal communication with an external telemetry coil located distant from the skin of the implanted patient immediately over the implantable communications coil arrangement without using load modulation of the communications coil arrangement; and wherein the patient fitting process includes interaction of the external fitting module via the external telemetry coil with the AIMD processor in the long range telemetry mode to adjust the operation of the AIMD processor in the normal operation mode based on the patient-specific performance characteristics. - View Dependent Claims (8, 9, 10, 11, 12)
