An implantable component (30) of a cochlear implant system comprising a
housing for a stimulator unit (31) that is adapted to output one or more
stimulation signals and an electrode assembly (30) adapted to apply
electrical stimulation in accordance with the output of the stimulator
unit (31). On implantation, the housing is positionable such that the
electrode assembly (20) extends from the housing at least initially in a
downward orientation toward the mastoid cavity before entering the
cochlea. An external component (50, 60 or 70) of a cochlear implant
system comprising a support for mounting to the ear of an recipient and
an external signal transmitter coil (53) wherein the signal transmitter
coil (53) is movably mounted to at least a portion of the support.
