Apparatus (10) is provided for treating an intervertebral disc (20) of a subject. The apparatus (10) includes a first electrode (30), configured to be inserted into a nucleus pulposus (40) of the disc (20), and a second electrode (32), configured to be placed outside of the nucleus pulposus (40), in a vicinity of the nucleus pulposus (40). A control unit (34) is configured to drive a current between the first and second electrodes (30, 32), and to configure the current to electroosmotically drive fluid between inside and outside the nucleus pulposus (40).
