The invention relates to a device (1) for neurostimulation comprising an electrode structure (100) for delivering stimulation pulses to a nerve (106) as well as for processing and extracting evoked compound action potentials (601), wherein the electrode structure (100) comprises at least a first anode (105.1), at least a second anode (105.2) opposing the first anode (105.1) and a plurality of cathodes (104.1, 104.2, 104.3) arranged between said anodes (105.1, 105.2), wherein said cathodes (104.1, 104.2, 104.3) are asymmetrically arranged with respect to said at least first and second anode (105.1, 105.2) to permit evoked compound action potential sensing (601) via the anode electrodes (105.1, 105.2) simultaneously with stimulation.
