An implantable cochlear implant electrode array ( 30 ) that can adopt a first, preferably straight, configuration selected to allow the array to be inserted into the cochlea and at least a second, preferably, spirally curved, configuration wherein the electrode array ( 30 ) is adapted to apply tissue stimulation. The electrode array ( 30 ) comprises an elongate carrier ( 31 ) having a proximal end ( 37 ), a distal end ( 34 ), and a plurality of electrodes supported by the carrier ( 31 ) at respective spaced locations thereon, the carrier ( 31 ) is formed, preferably moulded, to preferentially adopt the second configuration or another configuration different to said first configuration. The outer layer ( 33 ) is releasably connected to the elongate carrier ( 31 ) by an adhesive layer ( 32 ) and is formed so as to bias the carrier ( 31 ) into the first configuration when connected thereto. A method of forming the electrode array ( 30 ) is also disclosed.
