A cochlear implant electrode assembly device ( 10 ) comprising an elongate electrode carrier member ( 11 ), a first stiffening element ( 15 a), and a second stiffening element ( 15 b). The carrier member ( 11 ) is made of a resiliently flexible first material and has a plurality of electrodes ( 12 ) mounted thereon. The carrier member ( 11 ) has a first configuration selected to allow it to be inserted into an implantee's cochlea ( 30 ), a second configuration wherein it is curved in shape to match a surface of the cochlea ( 30 ), and at least one intermediate configuration between the first and second configurations. Both the first and second stiffening elements ( 15 a, 15 b) are made of a material relatively stiffer than said the material and in combination bias the elongate member into the first configuration. If either the first stiffening element ( 15 a) or the second stiffening element ( 15 b) are removed, the elongate member ( 11 ) adopts the at least one intermediate configuration.
