Abstract: An optical measurement device includes a light source, a first detector, and a second detector. The light source emits light to a measurement site of a patient and one or more detectors detect the light from the light source. At least a portion of a detector is translucent and the light passes through the translucent portion prior to reaching the measurement site. A detector receives the light after attenuation and/or reflection or refraction by the measurement site. A processor determines a light intensity of the light source, a light intensity through a tissue site, or a light intensity of reflected or refracted light based on light detected by the one or more detectors. The processor can estimate a concentration of an analyte at the measurement site or an absorption or reflection at the measurement site.

The method includes determining a second subset of simulated reflectance curves for a fine grid based on the closest fitting one of the simulated reflectance curves; determining a peak of absorption and reflection coefficients from the fine grid; and determining an absorption and a reflectance coefficient for the reflectance data points by performing a weighted average of the absorption coefficients and reflection coefficients from the peak.

Abstract: An implantable device with in vivo functionality, where the functionality of the device is negatively affected by ROS typically associated with inflammation reaction as well as chronic foreign body response as a result of tissue injury, is at least partially surrounded by a protective material, structure, and/or a coating that prevents damage to the device from any inflammation reactions. The protective material, structure, and/or coating is a biocompatible metal, preferably silver, platinum, palladium, gold, manganese, or alloys or oxides thereof that decomposes reactive oxygen species (ROS), such as hydrogen peroxide, and prevents ROS from oxidizing molecules on the surface of or within the device. The protective material, structure, and/or coating thereby prevents ROS from degrading the in vivo functionality of the implantable device.
