No
The description focuses on optical measurement and signal processing, with no mention of AI or ML algorithms for data analysis or interpretation.
No
The device is a monitoring system that measures tissue oxygen saturation. It is not designed to treat a condition but rather to provide diagnostic information.
Yes
The device is described as a "non-invasive monitoring system that measures an approximated value of percent hemoglobin oxygen saturation in tissue (StO2)" and is "indicated for use in monitoring patients during circulatory or perfusion examinations of skeletal muscle or when there is a suspicion of compromised circulation." These functions involve assessing a patient's physiological state to identify medical conditions, which falls under the definition of a diagnostic device.
No
The device description explicitly lists multiple hardware components, including a spectrometer, optical cable, calibrator, shield, and optical converter, in addition to the software.
Based on the provided text, the Hutchinson Technology Incorporated's InSpectra™ Tissue Spectrometer System, Model 325, is not an In Vitro Diagnostic (IVD).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
- InSpectra™ Function: The InSpectra™ system is described as a non-invasive monitoring system that measures an approximated value of percent hemoglobin oxygen saturation in tissue (StO2) directly on the patient's body. It uses light to interact with the tissue and measure the oxygen saturation.
- No Specimen Collection: The description explicitly states it is "non-invasive" and measures "in the upper extremity, shoulder, or lower extremity." There is no mention of collecting any biological specimens from the patient for analysis.
Therefore, because the InSpectra™ system operates directly on the patient's body without requiring the collection and analysis of biological specimens, it falls outside the definition of an In Vitro Diagnostic.

Device Description
This premarket notification (510(K) Notification) is submitted to obtain marketing clearance for the Hutchinson Technology Inc. BioMeasurement Division "InSpectraTM Tissue Spectrometer System, Model 325" (hereinafter referred to as InSpectraTM).
The InSpectraTM is designed to estimate the percent oxygen saturation of hemoglobin in a volume of tissue (StO2). This value is a reflection of localized perfusion of that tissue. The InSpectraTM is the same version of the previously cleared Hutchinson Technology Inc. (HTI) InSpectraTM Tissue Spectrometer System, Model 325, and represents changes to the indications for use statement.
The InSpectra™ is composed of the following components.
InSpectra™ tissue spectrometer system shown is comprised of the following components:
InSpectra™ Tissue Spectrometer: A spectrometer that contains light detection circuitry, a microprocessor, and a display screen.
InSpectra™ Optical Cable: A fiber optic light integration cable that contains one set of optical fibers to integrate wavelengths of light and transmit to the tissue, and a second set of optical fibers that receives light from the tissue and returns it to a photosensitive detector. Light emitting diodes in the optical cable connector are the light source. Optical cable distal tips are available in 12, 15, 20, 25, and 35mm spacing, and are differentiated by color. The 12-25mm cable tips are gray; the 35mm cable tip is blue. The optical cable is supplied with a storage case.
InSpectra™ Calibrator: A disposable module used to normalize the tissue spectrometer and calibrate during startup of the InSpectra tissue spectrometer system. The calibrator is available in two sizes: 12-25mm (labeled in black) and 35mm (labeled in blue).
InSpectra™ Shield: A disposable interface that attaches to the distal tip of the optical cable. The shield protects the measurement from ambient light interference, protects the optical fibers, and has an adhesive surface to attach to the patient for continuous monitoring and a liner to use for intermittent measurements. The shields are available in two sizes to fit the optical cables and are differentiated by color: 12-25mm (gray) and 35mm (blue). The shield is packaged in the calibrator. To ensure accurate Sto2 measurements, use a new InSpectra shield for each patient. Do not reuse.
InSpectra™ System Check: A method to check system measurements.
InSpectra™ OptoLink™ RS232 Optical Converter: A device used to export StO2, date, and time data from the spectrometer.
InSpectra™ Software: Software, which displays data from the tissue spectrometer on a computer during a live session or from an encrypted data file

Technological Characteristics:
The fundamental changes from the predicate device include:
- . A reworded indication-for-use statement (note: the fundamental intended use is retained)
Substantial Equivalence Rationale:
Essentially, the device and its predicate are identical with the exception of a reworded indication for use statement (the fundamental intended use remains unchanged). The devices share the intended use of measuring an approximated value of percent oxygen saturation of hemoglobin in a volume of tissue. In addition, they share the same design principles that incorporate a light source, fiber optic cables (which direct the light to and from the target tissue), optical detectors, analysis of specific wavelengths, and a software algorithm that provides the estimate of hemoglobin oxygen saturation.
Changes to the device necessitating this submission include only a change to the indications for use statement. The basic operating principles and measurement algorithm remain the same.
Test Reports:
Published clinical studies are presented showing that StO2 measurements provide valuable medical information in various disease states.
Conclusion:
Hutchinson Technology Inc. concludes that the InSpectra™ with changes to the indications for use is substantially equivalent the predicate device. InSpectra™ Tissue Spectrometer System, Model 325.
