1. A method for making a body implantable optical sensor, the method comprising the steps of:

  • forming a D-shaped, optically clear, tubular shell;

    mounting the sensor onto the flat inner surface of the D-shaped shell;

    forming two end caps dimensioned to seal the open ends of the shell, each end cap being formed to pass a sensor terminal;

    forming a sealing ring about one end of each of the end caps;

    heating the two end caps until the sealing ring reflows to form a hermetic seal; and

    heating the two end caps until the sensor terminals are hermetically sealed to the end caps.
