Intended Use
The noninvasive FORE-SIGHT Elite Absolute Tissue Oximeter is intended for use as an adjunct monitor of absolute regional hemoglobin oxygen saturation of blood under the sensors in individuals at risk for reduced flow or no-flow ischemic states and is indicated for use as follows: When used with large sensors, the FORE-SIGHT Oximeter is indicated for use on the brain of adults and transitional adolescents ≥ 40 kg.
Device Description
The FORE-SIGHT Elite Absolute Tissue Oximeter measures hemoglobin under the Sensor, allowing the clinician to continuously and accurately determine absolute levels of blood oxygenation saturation in the tissue (StO2). The Oximeter consists of a monitor unit, preamplifier assembly, and sensor uses multiple wavelengths of light in the range of 660 to 900 nm to precisely measure light absorption in tissue. Sensors are sized to provide targeted penetration depths appropriate for the tissue and patient populations of interest. The monitor unit controls the measurement sequence, regulating sensor light output and processing the detected light signals after amplification by the dual-channel preamplifier assembly. The FORE-SIGHT algorithm determines the StO2 values for the tissue under the sensor from the light absorption values and measured patient characteristics. The monitor unit provides simultaneous measurements on up to four sensors with both numeric and real-time graphical display formats. The monitor unit is a mains-powered device with a field-replaceable battery backup module. A touchscreen user interface allows configuration of the Oximeter including audible, on-screen, and dedicated visual alarm indicators. The monitor display can be replicated for simultaneous remote viewing through an auxiliary VGA video output. Measurement data can be exported through various interfaces such as USB and RS-232.
More Information

Not Found

No
The description mentions a "FORE-SIGHT algorithm" but provides no details suggesting it uses AI or ML techniques. The focus is on light absorption measurements and standard signal processing.

No
The device is used for monitoring purposes (diagnostics) and does not provide any treatment or therapy.

Yes

The device is intended to monitor absolute regional hemoglobin oxygen saturation of blood, which provides information about the patient's physiological state to identify potential medical conditions (reduced flow or no-flow ischemic states), thus serving a diagnostic purpose.

No

The device description explicitly details hardware components including a monitor unit, preamplifier assembly, and sensor, and mentions hardware verification and validation studies.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Description: The FORE-SIGHT Elite Absolute Tissue Oximeter is described as a noninvasive device that measures hemoglobin oxygen saturation under the sensors placed on the body (specifically the brain in this case). It uses light absorption to determine this measurement.
  • Lack of Sample Analysis: The device does not analyze samples taken from the body. It directly measures a physiological parameter within the body using external sensors.

Therefore, the FORE-SIGHT Elite Absolute Tissue Oximeter falls under the category of a noninvasive medical device rather than an In Vitro Diagnostic.

When used with Large sensors, the FORE-SIGHT Oximeter is indicated for use on the brain of adults and transitional adolescents ≥ 40 Kg.

FORE-SIGHT Monitor Technology Compared to Predicate Devices

The FORE-SIGHT Elite Absolute Tissue Oximeter compares substantially to the cited predicate devices in that they use fundamentally the same optical operating principle, called multi-distance diffuse reflectance spectroscopy. All cited monitors use light to examine a cross-section tissue microvasculature (a mixed bed of arterioles, capillaries and venules). The FORE-SIGHT Elite Monitor and predicate devices analyze the light that is returned after having passed through tissues. The spectroscopic analysis determines concentrations of hemoglobin in its oxygenated and deoxygenated states. All cited monitors calculate oxygen saturation which reflects the percentage of oxygenated hemoglobin in the sampled tissue.
