Method and system for recording and promoting the regeneration of peripheral nerves after injury that comprise one stimulating electrode that is implanted at the proximal segment of the nerve, at least one recording electrode that is implanted at the distal segment of the nerve, an implantable electronic unit, an implantable device releasing agents for stimulating nerve regeneration, such as a micro-pump, and a computing unit that is preferably placed extracorporeally for the communication of data and transfer of power to the electronic unit. The electrical signals that are produced by the distal segment of the injured nerves after appropriate electrical excitation of the distal segment of said injured nerve are recorded at various time instances. The analysis of the recorded electric signals is used to assess the state and progress of the regenerating neuroaxons; this assessment is used for determining various control parameters. Said control parameters are used by the electronic unit so as to control the release of stimulating agents in such a way that treatment is effective while keeping the administration of stimulating agents at safe levels. |
