Abstract

The present invention relates to a sieve electrode for connection to a nerve stump, which is composed of a thin flexible substrate (1) with a plurality of ports (2) for nerve filaments and several electrodes (3) that are disposed on at least some of said ports (2) on said substrate (1) and adapted for being electrically contacted via conductors (5) on said substrate (1), as well as of at least one counter-electrode (4). The substrate (1) presents tabs (6) protruding from the edge for fixing the substrate (1) on a face of the nerve stump, which serve, at the same time, as carrier of the counter electrode (4).With this sieve electrode a neuro-technological interface is provided that permits a low-lesion contact with the nerve stump at a maximum of useable surface for the ports.
