Abstract
An implantable neural tissue electrode assembly includes a cylindrical electrode lead with at least one electrode contact on the outer surface of the electrode lead. An active distal end fixation anchor is located at the distal end of the electrode lead and is adapted to fasten to adjacent tissue by rotation in a fastening direction. A passive rear fixation anchor is located on the outer surface of the electrode lead offset a longitudinal distance back from the distal end and has at least one curved blade with a blade tip directed away from rotation in the fastening direction. The rear fixation anchor is adapted to permanently fasten to adjacent tissue by rotation opposite to the fastening direction so that the blade tip cuts into the adjacent tissue, and the electrode assembly is adapted such that physiological induced strains are distributed along the electrode lead.
