The summary describes a light source accessory for surgical microscopes used for fluorescent visualization. There is no mention of any computational analysis, image processing, or algorithms that would suggest the use of AI or ML. The performance studies focus on the physical and optical characteristics of the light source and a usability study comparing fluorescence levels.
No.
The device functions as an accessory that provides excitation light for visualizing gliomas, not for treating them.
No
The device is an accessory light source used to provide supplemental excitation light for fluorescent visualization during neurosurgery. Its function is to illuminate the surgical field with specific light wavelengths (white light and 405 nm light) to enable visualization of fluorescently-labeled suspected gliomas. It does not perform any diagnostic analysis, interpretation, or detection of disease itself, but rather aids in the visualization of structures already identified as suspicious using a fluorophore.
No
The device is a light source, which is a hardware component, and the summary describes hardware performance testing.
Based on the provided information, the Myriad SPECTRA Light Source 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.
- Myriad SPECTRA Light Source Function: The description clearly states that the Myriad SPECTRA Light Source is a light source used during neurosurgery to provide supplemental excitation light for fluorescent visualization of suspected gliomas. It is an accessory to a surgical microscope and works with a fluorophore.
- No Sample Analysis: The device does not analyze any samples taken from the patient's body. It is used directly on the surgical field to enhance visualization during a surgical procedure.
Therefore, the Myriad SPECTRA Light Source falls under the category of a surgical accessory or medical device used in vivo (within the living body) rather than in vitro (in glass/outside the body).

Conclusion
The subject device and the predicate device are equivalent in terms of intended use and technological considerations. Risk assessments and performance testing have demonstrated that the design differences between the subject and the predicate device do not raise different questions of safety or effectiveness. Therefore, the Myriad SPECTRA Light Source is substantially equivalent to the legally marketed predicate device Leica FL400.
