A COCHLEAR IMPLANT ELECTRODE ARRAY

摘要

An electrode array (10) for a cochlear implant is formed with a carrier made, for example from silicone, is preshaped and is formed with a lumen. The array (10) is shaped to assume a first configuration. The array (10) can be straightened, and held in a straight configuration by inserting a stylet (44) into the lumen. The array (10) relaxes to a shape matching the curvature of the cochlea (48) when the stylet (44) is removed. The electrodes of the array (10) are disposed on one side of the array (10) to face the modiolus when that array (10) is inserted into the cochlea (48).
