1. A device for monitoring one or more body analytes within the body of a patient, the device comprising:
- at least one source configured to be positioned external to the body for emitting electromagnetic radiation;
at least one detector configured to be positioned external to the body for receiving electromagnetic radiation;
a plurality of subcutaneously insertable probes comprising a first probe and a second probe, each having a proximal portion configured to be positioned external to the body after insertion of the probe, and a distal portion configured for placement within a subcutaneous tissue of the patient upon insertion of the probe;
wherein the first probe is configured to;
transmit electromagnetic radiation from the at least one source to the subcutaneous tissue and toward the second probe to enable the electromagnetic radiation to interact with the one or more analytes being monitored, andtransmit the electromagnetic radiation that has interacted with the one or more body analytes from the subcutaneous tissue to the at least one detector.

19. A method for monitoring one or more body analytes concentration levels, the method comprising:
-
providing at least one source for emitting electromagnetic radiation, at least one detector for detecting electromagnetic radiation, and a plurality of subcutaneously insertable probes comprising a first probe and a second probe, each having a proximal portion and a distal portion, wherein the at least one source, the at least one detector, and the proximal portions of the probes are configured to be positioned external to the body, and the distal portions are configured for placement within subcutaneous tissue of a patient; emitting electromagnetic radiation from the at least one source, via the first probe, into the subcutaneous tissue and toward the second probe to allow the electromagnetic radiation to interact with the one or more body analytes being monitored; collecting the electromagnetic radiation that has interacted with the one or more body analytes; transmitting the collected electromagnetic radiation, via the first probe to the at least one detector; and determining a concentration level of the one or more body analytes based on the collected electromagnetic radiation. - View Dependent Claims (20, 21, 22, 23)
