Intended Use

This dialysis machine can be used for implementing and monitoring hemodialysis treatments for patients with acute or chronic kidney failure. The system can be used in hospital, health center and outpatient dialysis center settings when prescribed by a physician.

Device Story

The Dialog+ Hemodialysis System with Adimea option is a hemodialysis machine designed for clinical settings (hospitals, health centers, outpatient clinics). The Adimea option adds a double-beam spectrophotometer to the spent dialysate line to continuously measure UV absorption. This input data is processed by the Adimea software to calculate Kt/V, providing an online measure of dialysis treatment effectiveness. The system is operated by trained healthcare professionals. The output is displayed to the clinician to monitor treatment progress and effectiveness in real-time, allowing for potential adjustments to the dialysis procedure to optimize patient outcomes.

Clinical Evidence

Bench testing only. Verification and validation testing of the Adimea software and hardware components were performed to ensure performance specifications were met.

Technological Characteristics

System includes a double-beam spectrophotometer for UV absorption measurement in spent dialysate. Software performs Kt/V calculations. Operates as an integrated component of the Dialog+ Hemodialysis System. Connectivity and specific material standards are not detailed.

Indications for Use

Indicated for patients with acute or chronic kidney failure requiring hemodialysis (HD), including high flux and low flux hemodialysis, with or without pure ultrafiltration. For use in hospital, health center, or outpatient settings under physician prescription.

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.”

Dialog+0 Hemodialysis System with Adimea" Option DEVICE NAME:

COMMON OR USUAL NAME: High permeability hemodialysis system

DEVICE CLASSIFICATION:

Class II per 21 CFR §876.5860: Product Code KDI

PREDICATE DEVICE(S):

Dialog+0 Hemodialysis System

The Adimea option to the Dialog* Hemodialysis System DESCRIPTION: an alternate means of of provides obtaining effectiveness information on the patient's hemodialysis treatment during a double-needle procedure by continuously measuring the UV absorption in the spent dialysate line. This optional feature includes controlling software, ancillary hardware (a double-beam spectrophotometer) and electronics to operate the Adimea function. Adimea software provides the Kt/V calculation, an online measure of dialysis treatment effectiveness.

INTENDED USE: This dialysis machine can be used for implementing and monitoring hemodialysis treatments for patients with acute or chronic kidney failure. The system can be used in hospital, health center and outpatient dialysis center settings when prescribed by a physician.

## 510(k) Summary (continued)

The following types of renal replacement therapy can be carried out with the Dialog+ System:

Hemodialysis (HD) with or without phases of pure ultrafiltration -

- · High flux hemodialysis
- · Low flux hemodialysis

#### SUBSTANTIAL EQUIVALENCE:

The Dialog+ System with Adimea Option has the same intended use and utilizes the same fundamental technology as the predicate Dialog+ System. The Dialog+ System with Adimea Option is also similar to the predicate device in design and materials. The optional design feature that incorporates a spectrophotometric method of measuring the UV absorption in the spent dialysate line and the software calculation of KUV does not have a significant affect upon the fundamental technology of the Dialog+ System, since it operates as a discreet component / function of the Dialog+ System. Software requirements specifications for Adimea have been met and verification and validation testing is complete. This testing demonstrates that there are no differences between the predicate and the proposed device that raise new issues of safety or effectiveness.
