Abstract
Disclosed is a skin adherable device for monitoring analytes in interstitial fluid. The device includes an electromagnetic radiation emitting source and a transmitter for transmitting the electromagnetic radiation between the electromagnetic radiation emitting source and the interstitial fluid. The device further includes a detector, operating electronics and a power supply. The device may include a reusable part and a disposable part.

25. A device for monitoring one or more body analytes within the body of a patient, the device comprising:
-
at least one source external to the body for emitting electromagnetic radiation; at least one detector external to the body for receiving electromagnetic radiation; and at least one subcutaneously insertable probe having a proximal portion and a distal portion, the proximal portion being positioned external to the body after insertion of the probe, and the distal portion configured for placement within subcutaneous tissue of the patient upon insertion of the probe; wherein the at least one subcutaneously insertable probe enables; transmission of electromagnetic radiation in a first direction from the at least one source to the subcutaneous tissue, and transmission of electromagnetic radiation that interacts with the one or more body analytes in a second direction opposite to the first direction from the subcutaneous tissue to the at least one detector. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. 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 at least one subcutaneously insertable probe having a proximal portion and a distal portion, wherein the at least one source, the at least one detector, and the proximal portion of the probe being external to the body, and the distal portion being configured for placement within subcutaneous tissue of a patient; emitting electromagnetic radiation from the at least one source, via the at least one subcutaneously insertable probe, into the subcutaneous tissue; collecting the electromagnetic radiation that interacts with the one or more body analytes; transmitting the collected electromagnetic radiation, via the at least one subcutaneously insertable 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 (48, 49, 50, 51, 52)
