Abstract:
1. An implantable lead for a stimulation device comprising: an implantable planar array of electrodes comprising at least two columns of electrodes, at least one of the columns comprising a plurality of electrodes, each electrode having a front surface to be placed in contact with a tissue, a back surface opposite the front surface, and a sidewall extending away from the back surface and defining a cavity bounded by the sidewall and back surface; a plurality of conductors, wherein a distal portion of each of the conductors is attached to the back surface of a respective one of the electrodes; a carrier formed around the array of electrodes but not completely covering the front surface or back surface of the electrodes, wherein the carrier comprises a carrier material and maintains an arrangement of the electrodes; and a biocompatible material disposed over, and in contact with, the carrier, the distal portions of the plurality of the conductors, and the back surfaces of the electrodes, the biocompatible material filling the cavity defined by each electrode, wherein the carrier and the biocompatible material are different and the carrier and biocompatible material form a paddle containing the at least two columns of electrodes with the biocompatible material forming at least an exterior bottom surface of the paddle.
