Abstract
Apparatus is provided that includes a first electrode, configured to be implanted at a first anatomical site in a nucleus pulposus of an intervertebral disc of a subject, and a second electrode, configured to be implanted at a second anatomical site outside the nucleus pulposus of the disc. A control unit is configured to detect a pressure difference between the first and the second anatomical sites by detecting a streaming voltage between the first and the second electrodes, and, in response to the detected pressure difference, drive fluid between the nucleus pulposus and outside the nucleus pulposus by applying a treatment voltage between the first and the second electrodes. Other embodiments are also described.
