Abstract
An electrode system for neuromodulation and for recording of signals indicative of nerve activity is provided. The system can include a plurality of electrodes provided on a flexible, non-conductive substrate. The substrate can be rolled into a cuff for encircling a nerve bundle of a patient. The plurality of electrodes on the cuff can be interconnected using flexible conductors provided on the substrate. In one implementation, the electrodes can be interconnected using conductors that have spring-like configuration. Flexibility of the conductors allows the cuff to expand and contract with the nerve without causing excessive stress/strain at the nerve-cuff interface.
