Systems for the detection and delivery of neurochemical and electrical signals for functional restoration

A system comprising:

• a first implantable device comprising (i) a first control unit configured to provide wireless communication capabilities for said first implantable device and (ii) a first probe configured to detect, within a first region of a brain of a mammal, at least one of electrical signals within said first region of said brain or neurochemical signals that indicate concentrations of one or more neurotransmitters within said first region of said brain;
• a second implantable device comprising (i) a second control unit configured to provide wireless communication capabilities for said second implantable device, (ii) a first electrode configured to deliver electrical stimulation to targeted nerve tissue that is located outside of said brain and downstream of damaged or severed nerve tissue of said mammal and (iii) a second probe configured to detect neurochemical signals that indicate concentrations of one or more neurotransmitters within a region proximal to said targeted nerve tissue;
• and
• a third implantable device comprising (i) a third control unit configured to provide wireless communication capabilities for said third implantable device and (ii) a second electrode configured to deliver electrical signals to a second region of said brain that is different from said first region of said brain or a microfluidic delivery component configured to administer a neurochemical to said second region of said brain;
• wherein said first implantable device is configured to use said first control unit to wirelessly telemeter first information about said electrical signals or said neurochemical signals detected by said first probe of said first implantable device within said first region of said brain,
• wherein said second implantable device is configured to receive with said second control unit said first information that was wirelessly telemetered from said first implantable device, or to receive information derived from said first information, and to deliver electrical stimulation to said targeted nerve tissue outside of said brain based on said first information, or based on said information derived from said first information,
• wherein said second implantable device is configured to use said second control unit to wirelessly telemeter second information about said neurochemical signals detected by said second implantable device within said region proximal to said targeted nerve tissue outside of said brain, and
• wherein said third implantable device is configured to receive with said third control unit said second information that was wirelessly telemetered from said second implantable device, or to receive information derived from said second information, and to deliver electrical stimulation or administer neurochemicals to said second region of said brain based on said second information, or based on said information derived from said second information, about said neurochemical signals detected by said second implantable device within said region proximal to said targeted nerve tissue outside of said brain.
