System of implantable devices for monitoring and/or affecting body parameters
First Claim
1. 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 to modify 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 and sending addressable command data signals to said data signal transmitter in response thereto to selectively control or monitor the operation of one or more of said selectively addressed controllable devices in a closed loop manner in accordance with one or more controllable operating parameters 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.

Abstract
A system for monitoring and/or affecting parameters of a patient'"'"'s body and more particularly to such a system comprised of a system control unit (SCU) and one or more other devices, preferably battery-powered, implanted in the patient'"'"'s body, i.e., within the envelope defined by the patient'"'"'s skin. Each such implanted device is configured to be monitored and/or controlled by the SCU via a wireless communication channel. In accordance with the invention, the SCU comprises a programmable unit capable of (1) transmitting commands to at least some of a plurality of implanted devices and (2) receiving data signal from at least some of those implanted devices. In accordance with a preferred embodiment, the system operates in closed loop fashion whereby the commands transmitted by the SCU are dependent, in part, on the content of the data signals received by the SCU.
