1. A method comprising:

  • transmitting light via an optical fiber positioned proximate a sphincter within a patient;

    detecting reflected light via the optical fiber; and

    generating pressure information based on the detected light, wherein;

    the optical fiber is coupled to a flexible tube section that contains a reflective, flexible diaphragm mounted within the flexible tube section, and the flexible tube section is mounted within the sphincter; and

    the diaphragm reflects the light transmitted via the optical fiber and deflects in response to exertion of pressure against the flexible tube section by the sphincter.
