Presented herein are techniques that provide an external component of an implantable medical device system with the ability to use a single inductive coil assembly to both receive charging signals from an inductive charger and for bi-directional transcutaneous communication with an implantable component. In particular, an external component comprises a coil assembly comprising a first coil segment and a second coil segment. The first and second coil segments have a first electrically connected arrangement that is used to receive charging signals, and a second electrically connected arrangement that is used for the bi-directional transcutaneous communication.

Medical device component with dual-band coil assembly

Presented herein are contaminant-proof microphone assemblies for use with devices/apparatuses, such as auditory prostheses, that include one or more microphones disposed within a housing. A contaminant-proof microphone assembly in accordance with certain embodiments presented herein includes a microphone, a microphone plug, and a contaminant-proof membrane. The microphone plug has a first end coupled to the microphone and a second end that is configured to be positioned adjacent the contaminant-proof membrane. As such, the microphone plug is disposed between a sound inlet of the microphone and the contaminant-proof membrane. The microphone plug may be configured to mate with the housing or a gasket attached to the housing.

Contaminant-proof microphone assembly

Systems and apparatuses are used to transmit data between external and internal portions of auditory prostheses or other medical devices. The external portion of the auditory prosthesis includes a magnet and an implanted coil that provides stimulation to the device recipient. A shaped shield material can be placed between the external coil and the sound processing hardware to improve efficiency and effectiveness between the external coil and implanted coil. Adverse effects on tuning frequencies can be reduced by disposing the shield material away from the magnet.

Shielding device for signal transmission coil

A cochlear implant or other auditory prosthesis utilizes an external portion worn on a recipient's head and an internal portion implanted therein. Both portions include an associated coil that transmits a signal between the two portions. The external coil has a form factor substantially similar to the implantable coil. This form factor allows the external portion to be manufactured with a smaller footprint, since components that may otherwise interfere with signal transmission (e.g., batteries) may be installed closer to the external coil.
