Intended Use
Revaclear™ 300 and 400 dialyzers are indicated for treatment of chronic and acute renal failure by hemodialysis.
Device Description
This device is intended for the treatment of chronic and acute renal failure by hemodialysis. The intended population of this device is identical to those of the Polyflux HD-C4 (BIG), cleared for marketing in the United States under 510(k) notification K060195 and Polyflux HD-C4 (Small), cleared for marketing in the United States under 510(k) notification K072232. The membrane used in this device is a blend of polyarylethersulfone (PAES) and polyvinylpyrrolidone (PVP), which is equivalent to the membrane utilized in the Gambro Polyflux HD-C4 (BIG) and Polyflux HD-C4 (Small) single use hemodialyzers cleared for marketing in the United States under 510(k) Notifications (K060195 and K072232). Blood enters a blood inlet port where it is distributed to the hollow fibers. The patient's blood traverses the inside of the hollow fibers and exits the device via a blood exit port. By means of a hydrostatic pressure or transmembrane pressure which is created by a combination of positive and negative pressures across the membrane, plasma water along with certain lower and middle molecular weight solutes pass through the membrane and into the dialysate or filtrate compartment of the device. Uremic toxins and waste products are removed from the patient's blood in this device by means of both diffusion and convection through the membrane and into the countercurrent flowing dialysis solution during hemodialysis. The dialysate exits the devices via a dialysate outlet port.
More Information

No
The description focuses on the physical components and function of a hemodialyzer, with no mention of AI or ML. Performance studies are based on in vitro testing of physical characteristics.

Yes
The device is used to treat chronic and acute renal failure by hemodialysis, which directly addresses a disease state.

No

This device is a dialyzer, which is a therapeutic device used for the treatment of renal failure by hemodialysis, not for diagnosing conditions. It removes waste products from the blood.

No

The device description clearly describes a physical hemodialyzer with hollow fibers, blood and dialysate ports, and a membrane for filtering blood. This is a hardware device, not software.

Based on the provided text, the Revaclear™ 300 and 400 dialyzers are not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use is "treatment of chronic and acute renal failure by hemodialysis." This describes a therapeutic intervention performed directly on the patient's blood, not a test performed on a sample outside the body to diagnose or monitor a condition.
  • Device Description: The description details how the device physically interacts with the patient's blood to remove waste products. It describes a process of filtration and diffusion across a membrane, which is a core function of a therapeutic device, not a diagnostic one.
  • Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing a sample (blood, urine, etc.) to detect or measure specific substances.
    • Providing information for diagnosis, monitoring, or screening.
    • Using reagents or assays.

The device is clearly described as a hemodialyzer, which is a therapeutic device used in the treatment of kidney failure.

Summary of Performance Studies

In vitro testing was conducted to compare the performance of the proposed device configurations to the predicate configurations.

The performance characteristics of the submitted Revaclear 300 and 400 were determined according to requirements of ISO 8637" Cardiovascular implants and extracorporeal systems - Haemodialysers, haemodiafilters, haemofilters and haemoconcentrators".
The following characteristics were determined:

  • . Clearances of urea, creatinine and vitamin B12
  • Flow resistance of blood and dialysate compartments .
  • . Ultrafiltration coefficient

Biocompatibility of the submitted devices Revaclear 300 and 400 was evaluated according to current ISO 10993-1 and FDA Memorandum G-95-1 the device is classified as external communicating device, body contact with circulating blood and prolonged (>24h to ≤ 30 days) contact duration.

Revaclear 400 was chosen as a master product for testing as it is the biggest product in the product family.

The biological end-points studied for the device were cytotoxicity, sensitization/ intracutaneous reactivity, systemic toxicity (acute), systemic toxicity (subacute), genotoxicity and hemocompatibility. These endpoints are recommended to be evaluated by the ISO 10993-1 and FDA Memorandum G-95-1.

In addition, chemical analyses were performed to characterize the materials and to identify and quantify potential leachables as recommended by ISO 10993-1 and ISO 10993-18. According to the results of the biological in vivo testing and of the chemical analyses performed in these studies, Revaclear 300 and 400 dialyzers did not induce any adverse biological effects.

Mechanically induced hemolysis was tested in three experiments. In each experiment three filters were tested in parallel, whereas Revaclear 300 and Revaclear 300 filters with alternative materials were compared to Revaclear predicate devices.

Samples were taken every 15 minutes starting at the beginning of recirculation and free hemoglobin (fHb) levels were detected in duplicate according to 405 nm method.

Using the above described conditions for the test set-up no systemic increase in free hemoglobin as marker for hemolysis could be detected for the Revaclear 300 filters compared to the predicate device. These results indicate that the filters are comparable regarding hemolysis.

§ 876.5860 High permeability hemodialysis system.

(a)
Identification. A high permeability hemodialysis system is a device intended for use as an artificial kidney system for the treatment of patients with renal failure, fluid overload, or toxemic conditions by performing such therapies as hemodialysis, hemofiltration, hemoconcentration, and hemodiafiltration. Using a hemodialyzer with a semipermeable membrane that is more permeable to water than the semipermeable membrane of the conventional hemodialysis system (§ 876.5820), the high permeability hemodialysis system removes toxins or excess fluid from the patient's blood using the principles of convection (via a high ultrafiltration rate) and/or diffusion (via a concentration gradient in dialysate). During treatment, blood is circulated from the patient through the hemodialyzer's blood compartment, while the dialysate solution flows countercurrent through the dialysate compartment. In this process, toxins and/or fluid are transferred across the membrane from the blood to the dialysate compartment. The hemodialysis delivery machine controls and monitors the parameters related to this processing, including the rate at which blood and dialysate are pumped through the system, and the rate at which fluid is removed from the patient. The high permeability hemodialysis system consists of the following devices:(1) The hemodialyzer consists of a semipermeable membrane with an in vitro ultrafiltration coefficient (K
uf ) greater than 8 milliliters per hour per conventional millimeter of mercury, as measured with bovine or expired human blood, and is used with either an automated ultrafiltration controller or anther method of ultrafiltration control to prevent fluid imbalance.(2) The hemodialysis delivery machine is similar to the extracorporeal blood system and dialysate delivery system of the hemodialysis system and accessories (§ 876.5820), with the addition of an ultrafiltration controller and mechanisms that monitor and/or control such parameters as fluid balance, dialysate composition, and patient treatment parameters (e.g., blood pressure, hematocrit, urea, etc.).
(3) The high permeability hemodialysis system accessories include, but are not limited to, tubing lines and various treatment related monitors (e.g., dialysate pH, blood pressure, hematocrit, and blood recirculation monitors).
(b)
Classification. Class II. The special controls for this device are FDA's:(1) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Device—Part I: Evaluation and Testing,’ ”
(2) “Guidance for the Content of 510(k)s for Conventional and High Permeability Hemodialyzers,”
(3) “Guidance for Industry and CDRH Reviewers on the Content of Premarket Notifications for Hemodialysis Delivery Systems,”
(4) “Guidance for the Content of Premarket Notifications for Water Purification Components and Systems for Hemodialysis,” and
(5) “Guidance for Hemodialyzer Reuse Labeling.”
