The system comprised an implant and an external transmitter integrated in an eyeglasses-frame. The implant system converts the image patterns into interpretable stimulation signals, and data and energy are transferred to the implant by a telemetric link. Nerve cells inside the eye are then stimulated according to the captured images. The intact cells are innervated by means of 3-D stimulation electrodes that rest against the retina like small studs. As long as there is no damage to the optic nerve, the vision signals can be sent to the brain just like they are with healthy eyes In this system a surgery is underwent to graft existing nerve endings from the patients shoulder onto the pectoral muscle on his chest. Those nerves grew into the muscle about a specific period of time. Electrodes on the graft can now pick up any thought-generated nerve impulses to the now-absent limb and transmit those to the mechanical prosthesis, controlling the movements of the arm. Bionic arm work by detecting movements of chest muscle that have been connected to the remains of nerves that once went to the lost limb. The impulses emitted from the transplanted nerves into the chest muscle are picked up by the harness and processed by a computer which then directs very precise movements of the artificial limb.
