Abstract

A system consisting of a multiplicity of separate modules which collectively perform a useful biomedical purpose; the modules communicating with each other without the use of interconnecting wires. All modules may be intracorporeal or body mounted extracorporeal or some modules may be intracorporeal with others being body mounted extracorporeal. Signals are sent from one module to another by electromagnetic waves, by electrical signals using the body as an electrical conductor, or by acoustic waves. Physiologic sensor measurements sent from a first module causes a second module to perform some function in a closed-loop manner. One extracorporeal module can provide electrical power to an intracorporeal module; which power operates means for transferring data from the intracorporeal module to the body mounted extracorporeal module.

Claims6

Dependent claims

A medication delivery system for delivering medication into a patient, said medication delivery system comprising:

a sensor module including,
a sensor module housing adapted to be externally mounted on a patient's skin,
a needle adapted to be buried just beneath said patient's skin;
a glucose sensor physically connected to the tip of said needle,
a telemetry means mounted in said sensor module housing and electrically connected to said glucose sensor, for transmitting a signal carrying sensed glucose level information;
and
a medication release module adapted to be implanted in said patient for dispensing medication into said patient, including,
a medication release module housing adapted to be implanted in said patient,
a receiver means mounted in said medication release module housing for receiving signals transmitted by said telemetry means and for decoding sensed glucose level information,
a delivery means mounted in said housing and connected to said receiver means for causing medication to be delivered into said patient in accordance with said sensed glucose level information.
