§ 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

DESCRIPTION OF THE DEVICES:

The proposed device AK 98 Hemodialysis system, which is subject for this Traditional 510(k) premarket notification, consists of the following:

  • AK 98 dialysis machine
  • U9000 (Ultrafilter)
  • C-705 (Accessory Expansion chamber)

AK 98 Dialysis Machine

AK 98 is a standalone, software controlled hemodialysis machine intended to be used in a chronic care dialysis or hospital care environment for intermittent hemodialysis and/or isolated ultrafiltration treatments of patients with chronic or acute renal failure or fluid overload.

8

Image /page/8/Picture/1 description: The image features the word "Baxter" in a bold, italicized, sans-serif font. The text is a vibrant blue color, which contrasts with the white background. The font style gives the word a dynamic and forward-leaning appearance.

The goal of hemodialysis treatment is to remove waste products and excess fluid from the patient's bloodstream.

The AK 98 is to be used with compatible blood lines, liquid A-concentrate, sodium bicarbonate powder (BiCart) or liquid bicarbonate, Ultrafilter (U9000) and dialyzers (e.g. Revaclear, Polyflux).

The AK 98 pumps blood from the patient into the compatible bloodline, through the dialyzer (where the blood purification takes place), and then back to patient. The AK 98 handles treatment details, monitors and regulates the pressure and flow on both blood and fluid side, and continually monitors the operation of the dialysis machine.

The AK 98 dialysis machine can be divided into the following parts:

  • . Fluid unit - is used to produce the dialysis fluid (with the correct temperature, flow, and composition) from reverse osmosis water and concentrates (dry or liquid), and to transport the dialysis fluid through the dialyzer. The fluid unit offers Profiling of Ultrafiltration and/or conductivity, it also offers isolated Ultrafiltration. The fluid unit also includes "Clearance Measurement" (Diascan). The fluid unit maintains the dialysis fluid flow through the dialyzer and controls ultrafiltration. If a fault occurs, the machine enters a patient safe state, which depending on the fault, can include actions such as bypassing the dialyzer.
  • Blood unit - is designed to control and supervise the extracorporeal blood circuit. Double needle treatments are most common. Single needle treatments can also be performed with one pump (double clamp function). To prevent coagulation, anticoagulants can be administered by means of the integrated heparin pump. Disposable blood lines are used to transport the blood from the patient to the AK 98 machine and back to the patient.
  • . Power supply - The mains voltage is fed to an AC/DC converter within the AK 98, which generates different DC supplies for the machine.

Operator's panel - Both the blood unit and the fluid unit are controlled from the operator's panel. The panel contains a touch screen and a number of hard key buttons to the right of the screen. The screen allows the operator to interact with the dialysis machine by pressing various buttons. The hard-key buttons are language independent. The information in the display can be set to different languages.
