Laminated electrode for a cochlear implant

A method of forming an implantable electrode array that can adopt a first substantially straight configuration selected to allow the array to be inserted into an implantee's body and a preferential second spirally curved configuration wherein said electrode array is adapted to apply tissue stimulation, the method comprising the steps of:

• moulding an elongate carrier in a curved configuration in a first mould from a resiliently flexible material about an array of electrodes such that at least one of the electrodes has a surface that is at least adjacent an inner surface of the carrier;
• separately moulding a non-bioresorbable outer layer of the array in a second mould from a resiliently flexible material, the outer layer being moulded in a substantially straight or straight configuration;
• removing the elongate carrier and the outer layer from the respective first and second moulds;
• and
• straightening the carrier member and removably adhering it to the outer layer along a majority of the length of the outer layer using a bioresorbable adhesive.
