Abstract
A cochlear electrode device having the properties of axial stiffness and lateral flexibility and comprising a plurality of substantially incompressible, flat elements, with the elements being assembled adjacent and in contact with one another along a common axis to form a stack and with the elements being resiliently atached together so that the stack of elements is stiff in compression along the common axis and is flexible in tension when the elements are forced to deviate from the common axis by the application of an external force. A plurality of electrodes and connecting wires are supported by the stack at spaced apart locations along its length.
