Methods and systems for neural maintenance and regeneration
View Patent ↗Methods and systems are described that release one or both of a neurotrophin and an inhibitor of the degradation of the neurotrophin within or in the vicinity of a highly innervated tissue. In some embodiments, the method includes regulating the release of the neurotrophin and the inhibitor of degradation over time. In some embodiments, the method includes monitoring the concentration of the neurotrophin over time. The system may include a device or multiple devices for the release of the neurotrophin and the inhibitor as well as a controller. In some embodiments the system may include a sensor device and/or an imaging device capable of detecting the concentration of the neurotrophin over time. The release of the neurotrophin and inhibitor of degradation may be part of a controlled release system and regulated over time.
1. 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.
2. The system of claim 1 , wherein the controller generates at least one control signal that is transmitted to at least one of said neurotrophin release device and said inhibitor release device via said connection.
3. The system of claim 1 , wherein said neurotrophin release device and said inhibitor release device are implantable within the body of a mammal.
4. The system of claim 1 , further comprising a sensor capable of sensing a concentration of the at least one neurotrophin.
5. The system of claim 4 , further comprising an imaging device adapted to receive information from the sensor and capable of displaying the information from the sensor.
6. The system of claim 1 , wherein the controller is programmed to control 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 regulate the concentration of the at least one neurotrophin at least one target level.
7. The system of claim 1 , wherein the controller is programmed to control 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 modulate the concentration of the at least one neurotrophin toward at least one target level.
8. 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,
wherein during operation of the system and in response to receiving the sensing signal from the detector, the controller directs 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; and
a connection between the controller and at least one of the neurotrophin release device or the inhibitor release device.
