Indications for Use

Hemodialysis is indicated for patients with acute or chronic renal failure when conservative therapy is judged to be inadequate. The multiple use device can be reused on the same patient.

Device Story

Altra Flux® 200 is a high-permeability hemodialyzer acting as an artificial kidney. Device consists of semipermeable hollow fibers dividing blood and dialysate compartments. During hemodialysis, patient blood flows through hollow fibers; water and toxic waste products cross the semipermeable membrane into the dialysate compartment. Requires use with a controlled dialysate delivery system featuring an ultrafiltration controller to prevent excessive fluid loss. Used in clinical settings for patients with renal failure. This specific submission adds validation for multiple-use (reuse) on the same patient, with reprocessing performed via Renatron® system.

Clinical Evidence

No clinical data. Bench testing performed to validate the safety and effectiveness of the device after multiple-use reprocessing cycles according to the Renatron® operator’s manual.

Technological Characteristics

High-permeability hemodialyzer with semipermeable hollow fiber membrane. Requires external dialysate delivery system with ultrafiltration control. Mechanical device; no software or electronic components.

Indications for Use

Indicated for patients with acute or chronic renal failure requiring hemodialysis when conservative therapy is inadequate. Suitable for single or multiple use on the same patient.

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.”

## 510(k) Summary of Safety and Effectiveness

(in accordance with the requirements of SMDA 1990 and 21 CFR 807.92)

The assigned 510(k) number for the Altra Flux® 200 Hemodialyzer with multiple use labeling is: K970679.

## Device Information:

Trade Name: Altra Flux® 200 Hemodialyzer
Common Name: high permeability hemodialyzer or artificial kidney
Classification Name: Dialyzer, High Permeability with or without Sealed Dialysate System (21 CFR 876.5860) Product Code - 78 KDI

## Equivalent Device:

Altra Flux® 200 Hemodialyzer (single use device) cleared for marketing via Premarket Notification 510(k) number K926373/B.

## Device Description:

The Altra Flux® 200 multiple use hemodialyzer is the Altra Flux® 200 single use device with reuse labeling. Like the Altra Flux® 200 single use device, it is used as an artificial kidney in a hemodialysis system to treat patients with acute or chronic renal failure. The blood from a patient flows through the arterial tubing of the extracorporeal blood circuit to the blood compartment of the hemodialyzer, then returns through the venous tubing of the extracorporeal blood system to the patient. The hemodialyzer has semipermeable hollow fibers which divide the device into two compartments. When the blood passes through the hollow fibers, water and toxic waste products from the blood pass through the semipermeable membrane into the dialysate compartment. The dialysate delivery system controls and monitors the dialysate circulating through the dialysate compartment of the hemodialyzer.

A high permeability hemodialyzer has a semipermeable membrane that is more permeable to water than that of the conventional dialyzer. This device must be used in conjunction with a controlled dialysate delivery system that incorporates an ultrafiltration controller to prevent excessive loss of water from the patient’s blood. This highly permeable, semipermeable membrane may also permit greater loss of high molecular weight substances from the blood, compared with the conventional hemodialyzer.

**Intended Use:**

Hemodialysis is indicated for patients with acute or chronic renal failure when conservative therapy is judged to be inadequate. The multiple use device can be reused on the same patient.

**Comparison to Predicate Device:**

The Altra Flux® 200 Hemodialyzer with multiple use (reuse) labeling is identical to the currently marketed Altra Flux® 200 single use device. The product drawings, material list, chemical structure, production process flow for the membrane or dialyzer, and physical characteristics of the Altra Flux® 200 reusable hemodialyzer is identical to the currently marketed Altra Flux® 200 single use hemodialyzer which received marketing clearance via the original 510(k) Premarket Notification K926373/B, dated February 13, 1995.

The only difference between the two products is that the multiple use device has been validated for multiple uses. Reprocessing between uses was performed according to the Renatron® operator’s manual. Testing performed on reprocessed devices demonstrate that the Altra Nova® 200 multiple use hemodialyzer is as safe and effective as the currently marketed Altra Nova® 200 single use hemodialyzer.
