1. A blood glucose monitoring system comprising:

  • at least one fiber optic cable;

    a biocompatible sheath enclosing at least part of the at least one fiber optic cable;

    sensor material supported at one end of the sheath in optical communication with one end of the at least one fiber optic cable, the sensor material operative for diffracting electromagnetic waves received from the at least one fiber optic cable, the sensor material responsive to changes in an amount of glucose in contact therewith for changing a diffraction of the electromagnetic waves as a function thereof; and

    a biocompatible membrane covering the one end of the sheath, the biocompatible membrane in contact with the sensor material and operative for passing to the sensor material glucose from blood in contact with the side of the membrane opposite the sensor material while avoiding the passage of one or more blood proteins to the sensor material.
