Claim Text:
1. An electrode designed for implantation into the central nervous system (CNS) of a mammal, said electrode comprising: (i) a sole electrical lead coated with an insulator forming a passivation layer, or multiple electrical leads each being either coated with an insulator forming a passivation layer or imprinted on a carrier and coated with an insulator forming a passivation layer; (ii) an adhesive layer consisting of an upper adhesive layer and optionally a lower adhesive layer; and (iii) interleukin-1 receptor antagonist (IL-1ra), wherein said lower adhesive layer, when present, is covalently linked to the surface of said passivation layer; said upper adhesive layer is covalently linked to said lower adhesive layer, when present, or to the surface of said passivation layer; and the IL-1ra is covalently linked to said upper adhesive layer and actively inhibits scarring on or around the surface of said electrode when implanted into the CNS.
