Abstract
An artificial intervertebral disc (IVD) is provided for replacement of a degenerated intervertebral disc. The artificial IVD includes two endplates having oppositely-facing outward surfaces configured to engage respective intervertebral surfaces of the spinal column, and a chamber, which is disposed between oppositely-facing inner surfaces of the two endplates, and which includes a lateral wall including an electroosmotic membrane. A plurality of exposed electrode surface includes (i) one or more intra-chamber exposed electrode surfaces, which are located within the chamber; and (ii) one or more extra-chamber exposed electrode surfaces, which are located outside the chamber, in a vicinity of the chamber. Control circuitry is configured to drive at least one of the one or more intra-chamber exposed electrode surfaces and at least one of the one or more extra-chamber exposed electrode surfaces to electroosmotically drive liquid from outside the chamber to inside the chamber. Other embodiments are also described.
