NERVE INTERFACE ELECTRODE WITH FIBERS COMPRISING A POLYMER THAT IS RIGID OUTSIDE A NERVE AND FLEXIBLE INSIDE A NERVE AND A METHOD FOR PROVIDING SUCH FIBERS

摘要

A nerve interface (100) electrode has a plurality of fibers (104). Each fiber has a nonconductive sheath (108) surrounding a conducting wire (106). A conducting region (105) of each wire is exposed. The fibers are configured for insertion between fascicles of a nerve. Each sheath is formed by a layer of polymer material configured to switch from a high strength/tensile modulus state to a low strength/tensile modulus state upon introduction into a nerve.
