No
The summary describes a laser Doppler flowmeter system and analysis software, but there is no mention of AI, ML, or related concepts in the device description, intended use, or other sections. The analysis software is mentioned, but its function is described as "analysed," which is a general term and doesn't specifically indicate AI/ML.
No
The device is used for measuring and monitoring microvascular perfusion, which is a diagnostic function, not a therapeutic one.
Yes
The device is indicated for use in measuring microvascular perfusion, which is a physiological parameter used to assess the health or disease state of tissues, fitting the definition of a diagnostic device.
No
The device description explicitly mentions hardware components like the "PF 5001 Main Unit," "Function Units," "Blank Panel," and "Probes," indicating it is not solely software.
Based on the provided information, the PeriFlux System 5000 is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use describes measuring microvascular perfusion in vivo (in living humans and animals). IVDs are used to examine specimens in vitro (outside the body), such as blood, urine, or tissue samples.
- Device Description: The device uses probes attached to the body to collect information, which is consistent with in vivo measurement, not in vitro analysis of samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any other typical components of an IVD.
Therefore, the PeriFlux System 5000 is a device used for physiological measurement in vivo, not an IVD.

Device Description
The PeriFlux System 5000 Modular Laser Doppler Flowmeter System 5000 consists of a PF 5001 Main Unit, which can accommodate up to four Function Units. The first available Function Unit is the PF 5010 LDPM (Laser Doppler Perfusion Monitor) Unit. A PF 5990 Blank Panel takes the place of a Function Unit if less than four Units are required. Probes are attached to collect the information, which is analysed, using the PeriSoft analysis program.

Intended Use:
The PeriFlux System 5000 is indicated for use in measuring microvascular perfusion, in skin and muscle, in humans. It is also indicated for use in measuring microvascular perfusion in all tissues in animals.
Summary of the technological characteristics of the PeriFlux System 5000 compared with the PeriFlux System 4000:
The PeriFlux System 5000 Modular Laser Doppler Flowmeter is developed directly from the PeriFlux System 4000. The technology is the same but the design has been modified to simplify use of the instrument and allow customers to more easily choose the number of channels they need. Whereas the PeriFlux System 4000 presented the parameters Perfusion, CMBC (Concentration of Moving Blood Cells), Velocity and TB (Total Backscatter) to the user the PeriFlux System 5000 presents only Perfusion and TB (CMBC and Velocity are measured by the instrument to calculate Perfusion). The probes which are used with the PF 5010 LDPM Unit are identical in every way with those used for the PeriFlux System 4000 laser Doppler Flowmeter - they are interchangeable between the two systems.
