1. A system, comprising:
a headrest structure comprising an orientation feature configured to at least partially receive a head of a recipient of an implantable component of an implantable medical device;
a power unit, including:
an external coil disposed in the headrest structure, wherein the external coil is relatively more adjacent to the orientation feature of the headrest structure than to a backside of the headrest structure opposite the orientation feature,
at least one power supply, and
at least one processor configured to determine that the implantable component is in a proximity to the external coil and cause the external coil to transfer operational power from the at least one power supply to the implantable component; and
a data device, including:
a transceiver, and
one or more processors configured to determine that the implantable component is in a proximity to the external coil and cause the transceiver to transfer data signals to the implantable component by a wireless-communication protocol, wherein the one or more processors are separate from the headrest structure.
