Abstract: Presented herein are low-power active bone conduction devices that comprise an actuator that is subcutaneously implanted within a recipient so as to deliver mechanical output forces to hard tissue of the recipient. The low-power active bone conduction devices include an energy recovery circuit configured to extract non-used energy from the actuator and to store the non-used energy for subsequent use by the actuator. The low-power active bone conduction devices may also include a multi-bit sigma-delta converter that operates in accordance with a scaled sigma-delta quantization threshold value to convert received signals representative of sound into actuator drive signals.

Abstract: Embodiments presented herein are generally directed to techniques for separately transferring power and data from an external device to an implantable component of a partially or fully implantable medical device. The separated power and data transfer techniques use a single external coil and a single implantable coil. The external coil is part of an external resonant circuit, while the implantable coil is part of an implantable resonant circuit. The external coil is configured to transcutaneously transfer power and data to the implantable coil using separate (different) power and data time slots. At least one of the external or internal resonant circuit is substantially more damped during the data time slot than during the power time slot.

Abstract: Embodiments presented herein are generally directed to techniques for the transfer of isochronous stimulation data over a standardized isochronous audio or data link between components of an implantable medical device system. More specifically, as described further below, a first component is configured to generate dynamic stimulation data based on one or more received sound signals. The first component is configured to obtain static configuration data and to encode the dynamic stimulation data and the static configuration data into a series of isochronous wireless packets. The first component is configured to transmit the series of wireless packets over an isochronous wireless channel to a second component of the implantable medical device system.

Abstract: A BTE prosthetic device for use in a medical system or prosthesis comprises a connector configured to mechanically attach an auxiliary device of the system to the BTE prosthetic device.

The connector operates as an electromagnetic antenna for transmitting and/or receiving signals between the BTE prosthetic and other components of the medical system.

Abstract: Certain medical devices, such as auditory prostheses, have an implantable portion and an external portion. The implantable portion and external portion each include a transmission/receiver coil that communicates signals between the two portions. The implanted coil is implanted about the ear canal while the external coil is disposed about the pinna or in the ear canal itself. The proximity of the two coils allows for signal transmission between the implantable and external portions.
