Spinal cord implant systems and methods

Abstract

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Patent Application No. 60 / 881,056 filed on Jan. 17, 2007, the entirety of which is incorporated by reference herein.BACKGROUND[0002]Neural interfaces have emerged as possible interventions to reduce the burden associated with some neurological diseases, injuries, and disabilities, such as spinal cord injuries which can cause reduced sensation and mobility by damaging the nerve pathways between the brain and the rest of the body. Many neural interfaces take advantage of cortical plasticity, which is the brain's ability to reorganize its functions and their locations within the brain in response to chronic changes in the received sensory information.[0003]Researchers have considered implanting electrode devices to detect nerve signals or stimulate nerves. For example, signals detected in the brain or peripheral nervous system may be used to help control devices outside the body, such a...

AI Technical Summary

Benefits of technology

[0019]However, these stimulation therapies may not be effective for persons suffering from complete spinal cord injuries, when no motor function or sensation remains below the injury site, or for restoring more complex motor functions and skills such as standing up and walking. Therefore, a need remains for a device that enhances or restores motor function for persons suffering from spinal cord injuries, including more severe injuries such as complete spinal cord injuries.

Problems solved by technology
