Abstract
A three-dimensional annular electrode array (AEA) device is disclosed for use as a cybernetic neural interface for the neural control and sensory feedback of a bionic prosthetic device. The AEA, designed for implantation into a nerve, is comprised of a body (6) that can be coupled to a sleeve(s) (9, 10) or a sleeve(s) with a compartmentalized inner core (12) for connection to the proximal and distal ends of a transected nerve, respectively. Regenerating nerve axons capture and sequester laterally projecting electrode terminals (4) arranged in radiating clusters (5) of a plurality of electrode sub-array nodes (2) that make up the array; connected by a primary electrode lead (7) to a connector contact array (3) in a plurality of connectors (1) for connection to wired or wireless electromechanical systems.
