US Patent 7447551 Flexible implantable electrical stimulator array

A flexible implantable electrical stimulator array is provided, which is associated with a flexible circuit board, biocompatible materials, a cathode electrode array and an anode electrode array. By using the flexible circuit board, the implanting position and implanting way of the present electrical stimulator are more flexible. Hence, the present electrical stimulator is more humanized and more widely used. Besides, by a design of electrode arrays, electrical treatment area is enlarged and electrical treatment efficiency is improved.
