Abstract :
Multi-contact cuff electrodes were implanted in the median, ulnar, and radial nerves of an upper-limb amputee. 19 of 20 contacts produced selective, sensory response in the phantom limb from nerve stimulation. The neural interface has been stable for the duration of this ongoing chronic study, 12 months post-implant, with consistent threshold and impedance measures.
