Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
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.
Claim 2
Dependent Claim
165 words
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.
Claim 3
Independent Claim
14 words
The apparatus of claims 1 wherein, said needle is replaceably connected to said housing.
Claim 4
Independent Claim
45 words
The apparatus of claims 1 wherein, said telemetry means further comprising: a processing means connected to said glucose sensor for generating binary data corresponding to sensed glucose levels; and a telemetry transmitted connected to said processing means for transmitting a signal carrying said binary data.
Claim 5
Dependent Claim
68 words
The apparatus of claim 3 wherein said medication release module further includes a means for gathering and storing operational data and a transmitting means for transmitting a signal carrying said operational data, and wherein said sensor module further includes a telemetry receiver means for receiving said signal transmitted by said transmitting means, and a storage means connected to said telemetry receiver means for storing the received operational data.
Claim 6
Dependent Claim
78 words
The apparatus of claim 3 wherein said receiver means detects said signal carrying said binary data and wherein said delivery means includes: a memory means operably connected to said receiver means for storing said binary data, and a signal processing means, operably coupled to said receiver means and said memory means, for comparing the most recently received binary data with values previously stored in memory for causing said medication release modules to correspondingly alter the medication delivery rate.
Claim 7
Dependent Claim
19 words
The apparatus of claim 1 wherein the frequency of said signal is proportional to the level of blood sugar.
