Intended Use

The intended use of the device is for Volume controlled ultrafiltration and infusion of heparin through a blood pump for the treatment of renal failure or toxic conditions. This device may be used for High-Flux Hemodialysis.

Device Story

Dialog Dialysis Machine is an artificial kidney system for treating renal failure or toxic conditions. Device utilizes extracorporeal blood system with semipermeable membrane to separate substances in solutions. System features volume-controlled ultrafiltration and heparin infusion via blood pump; supports standard double-needle or optional single-needle dialysis procedures. Operated by clinical staff in a dialysis setting. Output consists of controlled fluid removal and anticoagulation delivery to manage patient blood chemistry. Benefits include effective waste removal and fluid balance for patients with compromised renal function.

Clinical Evidence

No clinical data. Bench testing only; finished products must meet required release specifications including physical testing and visual examination per Quality Control Test Procedures and GMP standards.

Technological Characteristics

Artificial kidney system; extracorporeal blood circuit with semipermeable membrane; volume-controlled ultrafiltration; heparin infusion pump; supports double or single needle configurations. Components do not contact patient directly.

Indications for Use

Indicated for patients with renal failure or toxic conditions requiring hemodialysis, including high-flux hemodialysis. Prescription use only.

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.”

PRODUCT NAME: Dialog Dialysis Machine

TRADE NAME: Single Patient Dialysate Delivery System

## CLASSIFICATION NAME:

Gastroenterology & Urology
Class II, 78 FKP, Single Patient Dialysate Delivery System
21 CFR 876.5820

## SUBSTANTIAL EQUIVALENCE¹ TO:

| 510 (k) Number | Applicant | Description |
| --- | --- | --- |
| K854367, K850569 Modified | Organon Teknika | HD Secura Dialysis Unit |
| K880459 | CD Medical | 480 High-Flow Ultrafiltration Control Dialysate |

## DEVICE DESCRIPTION:

In accordance with section 510(k) for the Federal Food, Drug, and Cosmetic Act, B. Braun Medical, Inc. intends to introduce into interstate commerce the Dialog Dialysis Machine. The Dialog Dialysis Machine is an artificial kidney system used for the treatment of patients with renal failure or toxic conditions. The device consists of an extracorporeal blood system for the separation of substances in solutions via a semipermeable membrane. The system allows for volume controlled ultrfiltration and/or infusion of heparin through a blood pump by utilizing a standard double needle or optional single needle dialysis procedure.

¹ The term "substantially equivalent" as use herein is intended to be a determination of substantial equivalence from an FDA -regulatory point of view under the Federal Food, Drug, and Cosmetic Act and relates to the fact that the product can be marketed without premarket approval or reclassification. These products may be considered distinct from a patent point of view. The term "substantially equivalent" is not applicable to and does not diminish any patent claims related to this product technology used to manufacture the product.

The components and materials used for the Dialog Dialysis Machine do not come into direct patient contact.

## SUBSTANTIAL EQUIVALENCE:

The Dialog Dialysis Machine is identical in materials, form, and intended use to the HD Secura Dialysis Unit currently marketed by Organon Teknika and the 480 High-Flow Ultrafiltration Control Dialysate marketed by CD Medical. There are no new issues of safety or effectiveness raised by Dialog Dialysis Machine.

## SAFETY AND EFFECTIVENESS:

All finished products are tested and must meet all required release specifications before distribution. The array of testing required for release include, but are not limited to; physical testing, visual examination (in process and finished product).

The physical testing is defined by Quality Control Test Procedure documents. These tests are established testing procedures and parameters which conform to the product design specifications.

The testing instruction records for each of the individually required procedures are approved, released, distributed and revised in accordance with document control GMP's.

Dear Mr. Alsberge:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register.
