The description details a spectroscopy system using near-infrared light and spatial resolution for measurement, with no mention of AI or ML algorithms for data analysis or interpretation.
No
The device is described as an "adjunct monitor" and explicitly states it "should not be used as the sole basis for diagnosis or therapy," indicating it provides information for diagnosis and therapy but does not perform therapeutic actions itself.
No
The "Intended Use / Indications for Use" section explicitly states, "The INVOS System should not be used as the sole basis for diagnosis or therapy." This indicates it is an adjunct monitor, not a primary diagnostic device.
No
The device description clearly outlines hardware components including a light source, photodiodes, and an adhesive sensor, indicating it is a hardware-based system, not software-only.
Based on the provided information, the INVOS 5100C is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the body (in vitro - "in glass"). This typically involves blood, urine, tissue biopsies, etc.
- The INVOS 5100C is a noninvasive device that measures oxygen saturation within the body (in vivo - "in the living"). It uses near-infrared light applied to the skin to analyze the tissue beneath.
The description clearly states it's a "noninvasive" system and that the sensor is "applied to the skin over the tissue of interest." This confirms it's an in vivo measurement, not an in vitro one.

Intended Use / Indications for Use
The noninvasive INVOS 5100C is intended for use as an adjunct monitor of regional hemoglobin oxygen saturation of blood in the brain or in other tissue beneath the sensor. It is intended for use in individuals greater than 2.5 kg at risk for reduced-flow or no-flow ischemic states. It is also intended for use as an adjunct trend monitor of regional hemoglobin oxygen saturation of blood in the brain or in other tissue beneath the sensor in any individual. The clinical value of trend data has not been demonstrated in disease states. The INVOS System should not be used as the sole basis for diagnosis or therapy.

Device Description
The INVOS 5100C is a 2 wavelength, diffuse reflectance spectroscopy system employing near infrared light to estimate the percentage of hemoglobin saturated with oxygen in tissue underneath the sensor. An adhesive sensor containing a light source and 2 photodiodes is applied to the skin over the tissue of interest and the returning light is analyzed for oxyhemoglobin and deoxyhemoglobin light absorption. Absorption signals from the photodiode closer to the light source are subtracted from those from the farther photodiode where the returning photons penetrate more deeply in the tissue. This suppresses absorption events originating in the outer layers of tissue that are common to both photodiodes, including the effects of skin pigmentation and subcutaneous tissues. This method of “spatial resolution” also allows estimation of scattering to improve measurement accuracy.
