- 6. The system control unit of claim 1 wherein said transmitter transmits a command data signal in the form of a modulated magnetic field.
- 7. The system control unit of claim 1 wherein said transmitter transmits a command data signal in the form of a modulated ultrasonic signal.
- 8. The system control unit of claim 1 wherein said program storage is modified in response to signals received by said data signal receiver.
- 9. The system control unit of claim 1 additionally including:at least one electrode; sensor circuitry; and wherein said sensor circuitry is configurable to generate a data signal representative of an electrical signal conducted by said electrode.
- 10. The system control unit of claim 1 additionally including:at least one electrode; stimulator circuitry; and wherein said stimulator circuitry is configurable to supply a sequence of drives pulses to said at least one electrode.
- 11. The system control unit of claim 10 wherein said supplied sequence of drive pulses is altered in response to a status signal received from at least one of said implantable addressable controllable devices.
- 12. The system control unit of claim 1 wherein at least one of said implantable addressable controllable devices operates as a stimulator and includes at least one electrode and stimulator circuitry for delivering a sequence of drive pulses to said at least one electrode and said system control unit periodically transmits a command signal to said stimulator in response to a status signal received from another one of said implantable addressable controllable devices.
- 13. The system control unit of claim 1 additionally comprising a rechargeable battery for powering said system control unit.
- 14. The system control unit of claim 13 wherein said battery has a capacity of at least one watt hour.
- 15. The system control unit of claim 1 wherein each of said implantable addressable controllable devices includes a rechargeable battery for powering each said implantable addressable controllable device.
- 16. The system control unit of claim 15 wherein said battery for each of said implantable addressable devices has a capacity of at least one microwatt-hour.
- 17. The system control unit of claim 1 wherein said system control unit is configured for implantation in the patient's body.
- 18. A system control unit configured for controlling and monitoring the operation of one or more other implantable addressable controllable devices wherein each of said controllable devices is contained within a sealed elongate housing having an axial dimension of less than 60 mm and a lateral dimension of less than 6 mm suitable for injection into a patient's body and wherein at least one of said devices is configurable as a stimulator to modify at least one parameter of the patient's body and at least one of said devices is configurable as a sensor to sense at least one parameter of the patient's body, said system control unit comprising:a control unit housing; a data signal transmitter for wireless transmission of command data signals to selectively addressed controllable devices; a data signal receiver for wireless reception of status data signals from selectively addressed controllable devices; a controller capable of accepting status data signals from said data signal receiver from one or more of said selectively addressed controllable devices operating as sensors and sending addressable command data signals to said data signal transmitter in response thereto to selectively control the operation of one or more of said selectively addressed controllable devices operating as stimulators to thereby operate in a closed loop manner for modifying at least one parameter of the patient's body; program storage for specifying the operation of said controller; and wherein said data signal transmitter, data signal receiver, said controller, and said program storage are disposed within said control unit housing.
- 19. The system control unit of claim 18 wherein said system control unit is configured for implantation in the patient's body.
- 20. The system control unit of claim 18 wherein said system control unit is configured for use outside of the patient's body.
