Abstract
Implantable stimulation devices are provided. Aspects of the devices include a multiplexed multi-electrode component configured for neural stimulation. The multiplexed multi-electrode component includes two or more individually addressable satellite electrode structures electrically coupled to a common conductor. The satellite structures include a hermetically sealed integrated control circuit operatively coupled to one or more electrodes. Also provided are methods of manufacturing wherein the application of laser welding is avoided in forming the satellite electrode structures and an integrated control circuit thereof is thereby shielded from mechanical stress during satellite manufacture. Additionally provided are systems that include the devices of the invention, as well as methods of using the systems and devices in a variety of different applications.
