1. A fiberoptic monitoring system, comprising:
- at least one optical fiber or fiber braid having a predetermined length; and
at least one diffraction grating integrated into a desired portion of the at least one optical fiber or fiber braid, the at least one optical fiber or fiber braid and the at least one diffraction grating configured together such that an effective refractive index of the at least one diffraction grating changes in tandem with at least one predetermined external stimulus.

Abstract
A patient monitoring system includes a plurality of diffraction gratings integrated along the length of an optical fiber, wherein the optical fiber and each grating are together configured to alter either the effective refractive index or grating periodicity of the respective grating at its corresponding location along the fiber in response to at least one desired external stimulus.

39. A method of monitoring a patient physiological parameter, the method comprising:
-
providing at least one fiberoptic sensor configured to reflect light at one or more desired wavelengths in response to at least one external stimulus received by the at least one fiberoptic sensor; configuring the at least one fiberoptic sensor to make physical contact with a patient body; transmitting a light to the at least one fiberoptic sensor; measuring a reflected light power level generated by the at least one fiberoptic sensor at each desired wavelength in response to the at least one external stimulus; and determining a change in at least one predetermined patient physiological parameter based on the reflected light power level at each desired wavelength. - View Dependent Claims (40, 41, 42, 43, 44)
