Active Telemetry Response for Hearing Implants

摘要

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.

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, 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.
