Abstract
An implant such as a cochlear assembly, or other similar device, includes an elongated therapeutic member arranged and constructed to perform a therapeutic function. The therapeutic member has at least two configurations: an insertion and a deployed configuration. The first configuration is selected to ease the insertion of the member into a body cavity. A stiffening member is used to urge said therapeutic member toward said first configuration. The stiffening member is made of a bioresorbable material so that after insertion, the stiffening member dissolves and allows the therapeutic member to assume the second configuration.
