Intended Use

The Phoenix® Hemodialysis delivery system is intended to be used to provide high flux and low flux hemodialysis, hemofiltration and ultrafiltration on patients weighing 15 Kilograms or more. The Phoenix system is to be used with either high or low permeability dialyzers. The device is intended to be used by trained operators when prescribed by a physician, in a chronic care dialysis facility or acute care unit.

Device Story

Phoenix® is a self-contained, microprocessor-controlled hemodialysis delivery system; provides hemodialysis, hemofiltration, and ultrafiltration. System integrates blood tubing set, dialyzer, heparin syringe pump, and dialysate concentrates (including BiCart® sodium bicarbonate). Operated by trained clinicians in acute or chronic care facilities. Device monitors and controls blood flow, fluid removal (ultrafiltration), dialysate flow, temperature, and conductivity. Microprocessor manages therapy parameters; provides real-time monitoring of arterial/venous pressures and transmembrane pressure. Output enables clinicians to deliver prescribed dialysis therapy; enhances treatment efficiency through modular design and automated control of fluid/solute exchange. Benefits include precise management of patient fluid balance and solute clearance during renal replacement therapy.

Clinical Evidence

Bench testing only. No clinical data presented. Evidence includes component-level hardware testing, software unit/regression testing, code inspections, and human factors evaluations to verify performance against specifications and international standards.

Technological Characteristics

Microprocessor-controlled hemodialysis delivery system. Modular structure. Features heparin syringe pump, dialysate preparation system (bicarbonate powder), and blood/fluid monitoring sensors. Connectivity: Standalone. Software: Embedded firmware (v3.35). Sterilization: Not applicable (device is a capital equipment system).

Indications for Use

Indicated for patients weighing ≥15 kg requiring high/low flux hemodialysis, hemofiltration, or ultrafiltration. Used in chronic care or acute care settings by trained operators 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.”
