Abstract
A nerve cuff electrode device comprising a cuff body having a smart memory polymer layer with a rigid configuration at room temperature and a softened configuration at about 37 C. The smart memory polymer layer has a trained curved region with a radius of curvature of about 3000 microns or less. A plurality of thin film electrodes located on the smart memory polymer layer. The thin film electrodes include discrete titanium nitride electrode sites that are located in the trained curved region. An exposed surface of each of the discrete titanium nitride electrode sites has a charge injection capacity of about 0.1 mC/cm2 or greater. Methods or manufacturing and using the device are also disclosed.
