Abstract
An implantable electrode array for providing a plurality of electrodes in communication with a target is described. A flexible, elastic support holds the electrodes in contact with the target tissue. A large number of electrodes can be provided and selectively activated/deactivated for specific functions. These functions include sensing activity of the target tissue and electrical therapy delivery. One technique to control the electrodes is conductive lines or filaments in the support with individual addressing of each electrode to activate/deactivate an individual electrode for a specific function.
