No
The device description clearly outlines a physical system including a portable pump, thermo isolated enclosure, electronics, batteries, oxygen cylinder, rotary pump, electromotor, and a disposable perfusion set with various physical components. While it mentions user-friendly firmware, the core functionality and components are hardware-based.
Based on the provided text, the KIDNEY ASSIST-transport is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is for the preservation, transport, and eventual transplantation of kidneys. This is a process related to organ viability and preparation for surgical implantation, not for diagnosing a condition or providing information about a patient's health status based on in vitro analysis of samples.
- Device Description: The device is described as a portable pump system for perfusing organs. It involves mechanical and environmental control (temperature, oxygenation, pressure) to maintain the condition of the organ. It does not involve analyzing biological samples (blood, tissue, etc.) outside of the body to provide diagnostic information.
- Lack of IVD Characteristics: The description does not mention any components or functions typically associated with IVDs, such as reagents, assays, analytical measurements of biomarkers, or the generation of diagnostic results.
- Predicate Device: The predicate device (K111521; Waves) is also a machine perfusion system for organs, further supporting that this type of device is not classified as an IVD.
In summary, the KIDNEY ASSIST-transport is a medical device used for organ preservation and transport, which falls under a different regulatory category than In Vitro Diagnostics.

The KIDNEY ASSIST-transport device is a thermo isolated enclosure wherein the kidneys are cooled passively by ice and a separate compartment holding the electronics, batteries and a dedicated medical oxygen cylinder. The device has sufficient battery power, holds enough oxygen and ice for an application period of 24 hours of hypothermic oxygenated perfusion. Pulsatile perfusion is generated by a rotary pump driven by an electromotor and is pressure controlled. User-friendly firmware allows the user to change perfusion parameters. Settings and results of the perfusion measurements are numerically displayed on the top of the enclosure. The single-use disposable KIDNEY ASSIST-transport perfusion set contains an easy to install preassembled perfusion cartridge for use in combination with the KIDNEY ASSIST-transport device. The purpose of the KIDNEY ASSIST-transport Perfusion Set is to perfuse human organs to be transplanted with an approved pump perfusion solution. Its set contains a reservoir, kidney holder, cannula, oxygenator, pump head, pressure sensor and compatible tubing. Pulsatile perfusion is maintained by the centrifugal pump head, pulsating the perfusion solution from the reservoir through the oxygenator to the kidney holder in the reservoir. Oxygenation is performed by the hollow fiber membrane oxygenator which facilitates the gas exchange with the perfusion solution. All kidneys will be perfused with University of Wisconsin Machine Perfusion Solution (UW-MP).
KIDNEY ASSIST-transport allows transportable machine perfusion to bridge the timespan between procurement and transplantation of kidneys.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Investigator Initiated Clinical Data: The published data of an investigator-initiated clinical study supports the claimed Performance and benefit of the KIDNEY ASSIST-transport. The KIDNEY ASSIST-transport provides safe hypothermic machine perfusion of kidneys, while adding beneficial oxygen during perfusion.
In detail, the objective of the investigator-initiated clinical study was to investigate the effects of oxygenation in HMP (hypothermic machine perfusion). Following standard organ procurement, kidney pairs (donors aged 50 or older, 38 % Female and 62 % Male) were cannulated and connected to the KIDNEY ASSIST-transport and perfused with UW-MP solution. Kidney pairs were randomly assigned to oxygenated (HMPO2) or nonoxygenated (HMP) perfusion in a paired design. In total 106 recipients were present in each study arm and followed one year post transplantation. Baseline characteristics were similar in both groups (HMPO2 : Age 60 years on average, 35 % Female, 65 % Male; HMP: Age 61 years on average, 37 % Female, 63 % Male). No data on ethnicity or race were reported.
The study results show that the addition of oxygen to HMP improves the outcomes compared to standard nonoxygenated HMP on kidney function and graft survival at 1 year after transplantation. HMPO2 significantly reduces the number of severe post-operative complications (including (S)AE) and even leads to a drastic 44% fewer rejections of the kidney after transplantation.

A detailed comparison overview is presented below
Intended use
Both KIDNEY ASSIST-transport and the predicate device (K111521) are intended to be used for the pulsatile hypothermic machine perfusion of kidneys for the preservation, transport, and eventual transplantation into a recipient. Both systems oxygenate the cold perfusion that is perfused through the kidney; however, this is not included in the Intended Use statement of WAVES. For KIDNEY ASSIST-transport, the oxygenation intention is included for clarification.

Principle of Operation
Principle of operation is equivalent. Both KIDNEY ASSIST-transport and the predicate device (K111521) consist of a pump unit and a single-use disposable perfusion set/cassette. UW-MP solution is pumped through the kidney while being cooled passively by ice and oxygenated through an oxygenator. Perfusion parameters (pressure, flow, resistance and temperature) are continuously monitored, displayed and stored, safeguarded by an alarm system. The systems incorporate embedded software for user interface and safety and control mechanisms.
Confiquration characteristics
Both KIDNEY ASSIST-transport and the predicate device (K111521) are comprised of reusable control/pump unit in combination with a single-use sterile perfusion set/cassette.
Perfusion Characteristics
Both KIDNEY ASSIST-transport and the predicate device (K111521) provide pressure-controlled pulsatile perfusion to the kidney. Perfusion characteristics on pressure are similar. The predicate device (K111521) WAVES allows a higher user-set pressure than the KIDNEY ASSIST-transport (100 mmHg vs 50 mmHg). In most clinical trials a mean pressure of 25 mmHg is used and demonstrated safety and efficacy of the technology. Therefore, the 50-mmHg limit in the KIDNEY ASSIST-transport does not induce new safety and effectiveness questions.
In addition, the predicate device (K111521) uses a displacement pump, where the KIDNEY ASSIST-transport incorporates a centrifugal pump to provide perfusion to the kidney. Since the perfusion parameters (pulsatile pressure and flow) are similar, this has no influence on the perfusion reaching the kidney. In principle, the centrifugal pump is considered a safer alternative for the displacement pump with respect to pressure build as it is an open pump system. Application period of both devices is 24 hours.
Cooling characteristics
Both KIDNEY ASSIST-transport and the predicate device (K111521) provides cooling by melting ice that is added to the insulated device.
Power source characteristics
Power source is identical in both systems: 4 Li-ion batteries, or auxiliary power supply can be used. The WAVES batteries are automatically charged while the device is on auxiliary power.
For the KIDNEY ASSIST-transport, the batteries must be charged using an external charger. As this means that less electrical power is needed inside the device, this situation is considered safer.
Oxygenation characteristics
Both KIDNEY ASSIST-transport and the predicate device (K111521) incorporate oxygenation of the cold perfusion solution that is pumped through the kidney. Both systems actively oxygenated the solution by means of an oxygenator that is part of the sterile single-use perfusion set/cassette. The oxygenator is part of the preassembled single-use sterile perfusion set.
Both systems use oxygen to oxygenate, where the WAVES also allows other gas mixtures.
Performance Data
Electrical safety and electromagnetic compatibility (EMC)
Electrical safety and EMC testing were conducted on KIDNEY ASSIST-transport. The system complies with the IEC 60601-1:2012 Edition 3.1, ANSI/AAMI ES60601-1:2005/(R)2012 standards for safety and the IEC 60601-1-2:2007 + AC:2010 standard for EMC.
Software
The KIDNEY ASSIST-transport contains software that shows compliance with IEC 62304:2006. The software for this device is classified as IEC 62304 Class B software and is considered as a "major" level of concern in the US.

Investigator Initiated Clinical Data
The published data of an investigator-initiated clinical study supports the claimed Performance and benefit of the KIDNEY ASSIST-transport. The KIDNEY ASSIST-transport provides safe hypothermic machine perfusion of kidneys, while adding beneficial oxygen during perfusion.
In detail, the objective of the investigator-initiated clinical study was to investigate the effects of oxygenation in HMP (hypothermic machine perfusion). Following standard organ procurement, kidney pairs (donors aged 50 or older, 38 % Female and 62 % Male) were cannulated and connected to the KIDNEY ASSIST-transport and perfused with UW-MP solution. Kidney pairs were randomly assigned to oxygenated (HMPQ2) or nonoxygenated (HMP) perfusion in a paired design. In total 106 recipients were present in each study arm and followed one year post transplantation. Baseline characteristics were similar in both groups (HMPO) : Age 60 years on average, 35 % Female, 65 % Male; HMP: Age 61 years on average, 37 % Female, 63 % Male). No data on ethnicity or race were reported.
The study results show that the addition of oxygen to HMP improves the outcomes compared to standard nonoxygenated HMP on kidney function and graft survival at 1 year after transplantation. HMPO2 significantly reduces the number of severe post-operative complications (including (S)AE) and even leads to a drastic 44% fewer rejections of the kidney after transplantation.
Conclusion
Based on the intended use, indications for use, principle of operall technological characteristics the KIDNEY ASSIST-transport has been shown to be substantially equivalent to the predicate device (K111521). Results of validation (including performance data) did not raise any questions on safety and effectiveness. It is concluded that the KIDNEY ASSIST-transport has been shown to be substantially equivalent to the legally marketed predicate device (K111521).
