Patent ID: 8267920

Claim:
A system comprising: a neurotrophin release device including a neurotrophin reservoir having at least one neurotrophin, the neurotrophin release device configured for releasing the at least one neurotrophin; an inhibitor release device including an inhibitor reservoir having at least one inhibitor of degradation of the at least one neurotrophin, the inhibitor release device configured for releasing the at least one inhibitor of degradation of the at least one neurotrophin; a detector configured to sense a concentration of the at least one neurotrophin and output a sensing signal; a controller capable of regulating the release of at least one of the at least one neurotrophin from the neurotrophin release device or the at least one inhibitor of degradation from the inhibitor release device, the controller programmed to control cooperatively releasing the at least one neurotrophin from the neurotrophin release device and the at least one inhibitor of degradation of neurotrophin from the inhibitor release device in order to elevate a concentration of the at least one neurotrophin in response to receiving the sensing signal from the detector; and a connection between the controller and at least one of the neurotrophin release device or the inhibitor release device.
