Active Telemetry Response for Hearing Implants [20160310735]

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.


Use of defined ferromagnetic materials for optimized implant coil coupling [9300161]

Abstract: A coil arrangement is described for an implantable medical system. A coil winding has a planar ring shape winding that encloses a coil interior area. The coil winding is adapted for placement parallel to a corresponding partner coil for communication of an implant link signal having an associated magnetic field component characterized by a coupling factor k representing fractional amount of magnetic field coupling between the coils. A coil coupling lens of magnetic conductive material has multiple lens surfaces and is adapted to shape the magnetic field component to increase the coupling factor and minimize self-heating of adjacent tissues due to the magnetic field component. The lens surfaces include: i. an inner lens surface lying substantially parallel to the plane of the ring shape winding and having an inner lens surface perimeter enclosed within the coil interior area, ii.


Pulse Width Adaptation for Inductive Links [20090043361]

Abstract: A signal processor is described for communication with an implanted medical device. An external processor transmits to the implanted medical device an implant data signal having a sequence of HI and LOW logic states at a fixed data bit rate. The pulse width durations of the HI and LOW logic states is adjustable in response to feedback telemetry data from the implantable medical device.
