The document describes a modular system for measuring micro-vascular perfusion and pressure using established technologies like Laser Doppler and pressure cuffs. There is no mention of AI, ML, or any related concepts in the intended use, device description, or performance studies.
No.
The device is intended for measuring, monitoring, and evaluating physiological parameters for diagnosis, and not for treating or providing therapy.
Yes
The device is explicitly stated to be "intended for Pulse Volume Recording (PVR) on human limbs and digits for diagnosis and evaluation of vascular disease in adults" and is described as offering "several tests for diagnosis and evaluation of vascular disease."
No
The device description clearly states it is a "modular multichannel system" consisting of a "Main Unit (PF 6001)" and various "function units" (PF 6010, PF 6050, PF 6040). It also describes the use of "optical fibre" and a "laser" for the Laser Doppler technology, indicating significant hardware components.
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.
- Device Function: The PeriFlux 6000 system, with its various units, measures physiological parameters directly on or within the body (in vivo).
- PF 6010 measures micro-vascular perfusion in skin, muscle, and animal tissues using Laser Doppler technology applied to the tissue.
- PF 6050 measures pressure cuffs and performs Pulse Volume Recording (PVR) on limbs and digits.
- PF 6040 monitors transcutaneous partial pressures of oxygen and carbon dioxide through the skin.
- Lack of Sample Analysis: The device does not analyze samples taken from the body. It interacts directly with the body to obtain measurements.
Therefore, the PeriFlux 6000 system falls under the category of in vivo diagnostic devices rather than in vitro diagnostic devices.

Intended Use / Indications for Use
PeriFlux 6000 equipped with PF 6010 is intended for measuring micro-vascular perfusion in skin and muscle in humans. It is also intended for measuring micro-vascular perfusion in all tissues in animals for research purposes. The PF 6010 is also intended for evaluating tissue response in skin to local heating and providing temperature stabilization of skin at blood perfusion measurement.
PeriFlux 6000 equipped with PF 6050 is intended for measuring the pressure cuffs, to simplify simultaneous measurements of perfusion and pressure when used in conjunction with a laser Doppler perfusion monitor. PeriFlux 6000 equipped with PF 6050 is also intended for Pulse Volume Recording (PVR) on human limbs and digits for diagnosis and evaluation of vascular disease in adults. It is not intended for use on neonates and pregnant women.
PeriFlux 6000 equipped with PF 6040 is intended for continuous non-invasive transcutaneous monitoring of the partial pressures of oxygen and/or carbon dioxide. It is intended for use on neonates, pediatrics, and adults not under gas anesthesia.

Device Description
The PeriFlux 6000 is a modular multichannel system that offers several tests for diagnosis and evaluation of vascular disease in one instrument. It consists of a Main Unit (PF 6001), which accommodates up to eight different function units of the same type or of different types enabling simultaneous measurements of several parameters. Currently, one type of unit –PF 6040 tcpO2/pCO2 Unit– is available for the US market. Two more units have been developed:
- PF 6010 LDPM/Temp Unit
- PF 6050 Pressure Unit
The PeriFlux 6000 equipped with PF 6010 function units measures microcirculatory blood flow using Laser Doppler technology. In combination with the PF 6050 function unit to inflate blood pressure cuffs and to register the cuff pressure, it enables a range of different tests, including ankle pressure, toe pressure, skin perfusion pressure (SPP), pulse volume recording (PVR), segmental pressures, heat provocations and post-occlusive reactive hyperemia (PORH).
In Laser Doppler Perfusion Monitoring, an optical fibre leads light generated by a laser to the LDPM probe tip, which rests against the tissue. The beam of light will enter the tissue and become scattered. Blood cells moving within the volume illuminated by the beam will cause the light to change frequency. This change in frequency is called a Doppler shift and it is used to calculate the blood flow in the illuminated tissue.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance Testing - Bench: Laser Doppler Perfusion Monitoring is an intricate measurement, involving more electronics and calculations than measurements of the other parameters. Also, the PF 6010 measures over a higher frequency bandwidth than the PF 5010. We have therefore tested how the clinically relevant parameter, blood perfusion, correlates between these two systems. The tests show that the signals correlate very well between the two systems and that they can be regarded as equivalent.
Performance Testing - Animal: No performance tests on animals are submitted.
Performance Testing - Clinical: No clinical performance tests are submitted.

Device Description
The PeriFlux 6000 is a modular multichannel system that offers several tests for diagnosis and evaluation of vascular disease in one instrument. It consists of a Main Unit (PF 6001), which accommodates up to eight different function units of the same type or of different types enabling simultaneous measurements of several parameters. Currently, one type of unit –PF 6040 tcpO2/pCO2 Unit– is available for the US market. Two more units have been developed:

Environment of use
The PeriFlux 6000 instrument is intended for professional use in a hospital environment, laboratory environment and in a hospital intensive care unit environment.
Comparison of technological characteristics with the predicate devices
There are no technological differences between the instrument approved in K131253 and the current Periflux 6000 when equipped with PF 6040 besides the ability to host the other function units. Predicate device No 2 is listed for completeness and will not be discussed further. The Periflux 6000 and the primary predicate device have Laser Doppler Perfusion Monitoring as a technological principle. It is based on measuring the Doppler shift of laser light scattered in the tissue as a measure of micro-vascular blood flow.
At high level, the Periflux 6000 and the primary predicate device are based on the following same technological elements:
- An infrared laser with laser class 1 (IEC 60825-1:2007, 21 CFR 1040.10 and ● 1040.11)
- Measurement through optical fibre probes. ●
- Temperature measurement and control in the probe possible ●
- Measurement and control of pressure in blood pressure cuffs ●
- Possibility to combine different function units in one device o
The following technological differences exist between the PeriFlux 6000 and the primary predicate device:
- Use of an SVGA display with touch screen operation ●
- Up to 8 function units in one device (compared to 4 in primary predicate) ●
- Laser Doppler Perfusion Monitoring and probe heating combined in one function ● unit
- o Perfusion calculated from a larger frequency bandwidth.
- o 6 individually controlled cuff connectors and a built-in pump.

PeriFlux 6000 - 510(k) Summary
6010 measures over a higher frequency bandwidth than the PF 5010. We have therefore tested how the clinically relevant parameter, blood perfusion, correlates between these two systems. The tests show that the signals correlate very well between the two systems and that they can be regarded as equivalent.
Performance Testing - Animal
No performance tests on animals are submitted.
Performance Testing - Clinical
No clinical performance tests are submitted.
Conclusion
The discussion of similarities and differences between the new device and the predicate device shows that the new device is similar to the predicate device in most of the relevant properties. The intended use of the devices is the same. A few differences in technological characteristics have been found and the discussion concludes that these differences do not raise different questions of safety and effectiveness, nor do they adversely affect safety and effectiveness. The PeriFlux 6000 simply follows the state of the art in standards and available technology to create a safe, effective and convenient device. Temperature and pressure are measured using the same technology and use the same type of sensors in PeriFlux 6000 as in PeriFlux System 5000 and comparative testing shows that Laser Doppler Perfusion measurements on these two systems can also be regarded as equivalent.
The conclusion is that the new device PeriFlux 6000 is substantially equivalent to the predicate device PeriFlux System 5000.
