The document describes image processing and data capture but does not mention AI, ML, or related terms like deep learning. The performance studies focus on visualization and measurement accuracy, not algorithmic performance metrics typically associated with AI/ML.
No.
The device is explicitly stated to "not diagnose or treat skin wounds," indicating it is not a therapeutic device but rather an imaging and measurement tool for clinicians.
No
Explanation: The "Intended Use / Indications for Use" section explicitly states, "The MSI does not diagnose or treat skin wounds." Instead, it is described as a tool to "allow clinicians diagnosing and treating skin wounds to View and digitally record images... Measure and digitally record the size..." and record other imaging data. This indicates it is an imaging and measurement tool for clinicians to use, not a diagnostic device itself.
No
The device description explicitly states the MSI Kit includes hardware components such as the MSI handheld imaging tool itself, a USB-C cable, a wall adapter, and a carrying case. The MSI device also contains imaging modalities (white light, autofluorescence, thermal), LEDs, sensors, and a battery, all of which are hardware.
Based on the provided information, 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. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The MSI is described as a "handheld imaging tool" that allows clinicians to view, record, and measure skin wounds using different imaging modalities (white light, autofluorescence, thermal). It explicitly states, "The MSI does not diagnose or treat skin wounds."
- Lack of Sample Analysis: The device operates by imaging the wound directly on the patient's skin. It does not analyze samples taken from the body.
- Focus on Visualization and Measurement: The primary functions are visualization, digital recording, and measurement of the wound's characteristics (size, fluorescence, temperature). These are observational and quantitative tools, not diagnostic tests performed on biological samples.
While the device provides information that can be used by a clinician in the diagnostic and treatment process, the device itself is not performing an in vitro diagnostic test. It's a tool for visualizing and documenting the wound in situ.

Comparison of the Technological Characteristics between the MSI Kit and the Predicate Devices
Both the MSI and the MolecuLight i:X share key core fluorescence functionality and technological characteristics (see Table 3). Both devices use overlapping excitation wavelengths to excite naturally occurring fluorophores in the wound and surrounding tissue, which in response emit light that is filtered and measured by a CMOS camera to produce an image. There is substantial overlap between the spectral profiles of the MSI and MolecuLight i:X's excitation LEDs. Specifically, the MSI uses a 395 nm light emitted from LEDs as the fluorescent excitation light whereas the predicate MolecuLight i:X uses a 405 nm light emitted from LEDs. MSI captures emission wavelengths > 450 nm whereas the predicate captures emission wavelengths from 500-545 nm and 600-665 nm. In both devices image processing occurs to produce fluorescence images. White light images are also collected. Any differences in technological characteristics do not raise different questions of safety or effectiveness compared to the predicate device.
For thermal imaging, the MSI and the WoundVision Scout predicate share very similar functionality and technological characteristics (see Table 4). Both devices use an infrared sensor to capture a thermal image of the wound. Both devices calculate a central tendency of temperature and use a color-coded display to produce a thermal image. Specifically, the MSI calculates the median temperature, and then uses a color coded scale to display the relative thermal image with a score of -4 to +4 °C from the median. WoundVision Scout calculates the mean temperature (rather than median) and uses a color-coded scale to display the relative thermal image. Both devices also provide white light images, and wound area measurements. Any differences in technological characteristics do not raise different questions of safety or effectiveness compared to the predicate device.
