Patent ID: 8660661

Claim:
An implantable electrode which comprises at least one electrical conductor having a proximal connecting region for a pulse generator, and a distal region; and at least one working electrode configured to be connected to the pulse generator by way of the at least one electrical conductor, wherein the at least one working electrode comprises an electrically active surface; wherein the implantable electrode includes at least one portion which contains elementary magnesium in a form of metal particles, wherein the metal particles are of a diameter between 0.1 μm and 500 μm; wherein the elementary magnesium is configured such that a first period of time of decomposition starts immediately after implantation and is maintained until at least region-wise the implantable electrode is covered with connective tissue, such that the at least region-wise comprise at least regions of the elementary magnesium-containing portion that are covered to more than 50% of area with said connective tissue; wherein the first period of time is between 1 and 90 days; and wherein the elementary magnesium-containing portion is immediately adjacent to the at least one working electrode; and, at least one magnesium-bearing portion; wherein the at least one magnesium-bearing portion covers the electrically active surface of the at least one working electrode; wherein the at least one magnesium-bearing portion comprises a thickness between 10-100 μm and is configured such that a second period of time of decomposition is maintained, and such that the at least one magnesium-bearing portion comprises more than 90% by weight decomposed; and wherein said second period of time is between 1 hour and 120 hours.
