A system for transferring spinal cord signals comprises a superior electrode and an inferior electrode. The superior electrode interfaces with a first portion of a spinal cord of a human body； and the inferior electrode interfaces with a second portion of the spinal cord. The superior electrode has at least one superior contact for receiving signals from the first portion of the spinal cord to transmit to the inferior electrode； and the inferior electrode has at least one inferior contact for transmitting signals received from the superior electrode to the second portion of the spinal cord.
