Regulatory Classification

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).

Special Controls

*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.”

#### DESCRIPTION OF THE DEVICE

The line of Asahi AM-BIO Extended Range Series Dialyzers (AM-BIO-HX series) is a family of hemodialysis membranes, or hollow fiber dialyzers, developed to provide safe and effective hemodialysis over ranges of dialyzer patient treatment requirements. The device is intended for use in patients who have chronic renal failure or acute renal failure, for only single use.

The membrane fibers are made of modified cellulose (i.e., alkyl ether polymer grafted cellulose), derived from cuprammonium rayon. The cuprammonium rayon is manufactured to have a thin layer of modified cellulose exposed to blood contact surfaces. The modification to the cellulose vields the fiber more compatible to the patient's blood, manifested through lower complement activation (C3g and C52) when compared to regular cellulose membrane dialyzers.

The membranes are housed within a plastic casing of styrene butadiene block polymer. Non-removable casing end caps are also made of styrene butadiene block polymer. The potting material (sealant) is polyurethane and the port caps (stoppers) are made of hydrogenated styrene butadiene block polymer. Like the AM-BIO Series Dialyzers, the AM-BIO Extended Range Series Dialyzers will be offered for sale in both a "wet" model and a "dry" model. The wet and dry dialyzers are identical to each other except that the wet models are filled at the factory with a fluid to facilitate priming by the user and the dry models are not filled. The use of a wet or dry dialyzer is a matter of user preference. The fluid in wet dialyzers is made of water containing 600 ppm sodium pyrosulfite and 300 ppm sodium carbonate. Asahi AM-BIO Extended Range Series Dialyzers are sterilized by gamma radiation before shipment.

## Comparison of Device Characteristics to Predicates

The indications for use, design, and manufacturing of the Asahi AM-BIO Extended Range Series Dialyzers are the same as a predicate device, the AM-BIO Series Dialyzers. The AM-BIO Extended Range Series Dialyzers have the same materials and construction as the AM-BIO Series Dialyzers, but with extended range of performance specifications to accommodate a more diverse patient population. The intended changes in performance specifications are achieved by changing the pore size of the dialyzer fibers. Note, the AM-BIO Extended Range Series Dialyzers are labeled for only single use.

## Non-clinical Testing

In-vitro testing of the AM-BIO Extended Range Series Dialyzers includes the following:

- Permeability saline .
- ◆ Permeability - bovine plasma
- Urea clearance rate ●
- Creatinine clearance rate ●
- . Phosphate clearance rate

{3}------------------------------------------------

Additionally, the following testing supports the biocompatibility of the AM-BIO Extended Range Series Dialyzers:

- Cytotoxicity ●
- Sensitization .
- Irritation or Intracutaneous Reactivity .
- Systemic Toxicity (Acute) ●
- Genotoxicity: ●
- Hemocompatibility .
