System of implantable devices for monitoring and/or affecting body parameters
First Claim
1. A device suitable for implantation via injection beneath the skin of a patient'"'"'s body, said device comprising:
- a sealed elongate housing having an axial dimension of less than 60 mm and a lateral dimension of less than 6 mm, the housing comprising a first end cap forming electrode and a second end cap forming electrode, the electrodes being suitable for tissue stimulation and body parameter sensing;
power consuming circuitry comprising the electrodes, said power consuming circuitry being responsive to a remotely provided command data signal to thereby modify the operation of said device; and
a battery disposed in said housing electrically connected to said power consuming circuitry for powering said circuitry;
wherein said battery comprises;
a case;
a first conductive plate mounted in said case;
a second conductive plate mounted in said case in opposed spaced relationship relative to said first plate;
an electrolyte disposed between said first and second plates; and
wherein said plates are formed to include gaps to accordingly minimize eddy currents therein; and
wherein said battery has an energy capacity of at least 1 microwatt hour.

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.
