Company Name: a. 14620 NW 60th Avenue Company Address: b. Miami Lakes, Florida 33014-9308 (305) 823-5240 Company Phone: C. Amaury Sanchez Contact Person: ರ. Compliance Regulatory Senior Coordinator February 24, 1999 Date Summary Prepared: e. ## DEVICE IDENTIFICATION ll. - PS 15® Hemodialyzer Trade/Proprietary Name: a. - Hemodialyzer Common Name: b. - High Permeability Hemodialyzer 21 CFR Classification Name: C. 876.5860 ## Substantially Equivalent Legally Marketed Device: III. | Company | Device | 510(k) No. | Date Cleared | |---------------------------|---------------------------------------|------------|--------------| | Althin Medical, Inc. | Altrex 170<br>Hemodialyzer | K945597 | 3/8/95 | | Fresenius Medical<br>Care | Fresenius F60<br>Polysulfone Dialyzer | K852251 | 7/25/85 | su {1}------------------------------------------------ The PS 15® Hemodialyzer is substantially equivalent to other predicate devices currently in commercial distribution in terms of their intended use. The fundamental technical characteristics are similar to those of the predicate devices. #### IV. DEVICE DESCRIPTION The PS 158 Hemodialyzer consists of approximately 13,000 polysulfone hollow fibers encapsulated in polyurethane resin with an outer housing and headers made of Polycarbonate. The device is packaged in a blister package composed of Glycol modified Polyethylene Terephtalate for the bottom web, and a foil laminater for the top web. The PS 15® Hemodialyzer has two compartments, the blood compartment and the dialysate compartment, separated by the polysulfone permeable membrane and and flows from the patient access site through the tubing of the extracorporeal. system and accessories to the blood compartment of the dialyzer. From the blood compartment, undesirable substances in the blood pass through the membrane into the dialysate compartment of the dialyzer. Circulation and monitoring of dialysate into flow through the dialysate compartment is controlled by the dialysate delivery system, while the ultrafiltration controller prevents excessive loss of yeater from the patient's blood. ## V. INTENDED USE OF THE DEVICE The disposable PS 150 Hemodialyzer is Intended for use in conjunction with commercially available blood tubing, blood access devices and relation we hemodialysis equipment. The intended use of the PS 150 Hemodialyzer and predicate Altrex 170 Hemodialyzer is identical in that the devices are intended for hemodialysis in patients with acute or chronic renal failure, when conservative therapy is judged to be inadequate. Both devices are labeled as sterite, nonpyrogenic, and for single use only. The devices are restricted to sale by or on the order of a physician. ## VI. COMPARISON OF TECHNICAL CHARACTERISTICS The design configuration of the PS 15® Hemodialyzer is similar to legally marketed devices from Althin Medical, Inc. and polysulfone membrane from Fresenius Medical Care. {2}------------------------------------------------ With the exception of polysulfone, the PS 15® Hemodialyzer and predicate Altrex 170 use identical materials, similar manufacturing processes, the same package and are gamma sterilized. The polysulfone membrane used in the PS 15® Hemodialyzer is substantially equivalent to other polysulfone membranes marketed by Fresenius Medical Care. Results from the functional, chemical and biological tests demonstrate that the PS 15® Hernodialyzer is equivalent to a legally marketed device. A comparison of the features of the PS 15® Hemodialyzer and those of the previously cleared predicate device are presented in the following table. | Feature | PS 15®<br>Hemodialyzer | Altrex 170<br>Hemodialyzer | |----------------------------------------------------|---------------------------------------------------------------------|---------------------------------------------------------------------------| | Classification Name | High Permeability<br>Hemodialyzer or<br>artificial kidney | High Permeability<br>Hemodialyzer or<br>artificial kidney | | Classification | Class III device per<br>21 CFR 876.5860(b) | Class III device per 21<br>CFR 876.5860(b) | | Panel | Gastroenterology and<br>Urology | Gastroenterology and<br>Urology | | Product Code | 78KDI | 78KDI | | Indications for Use | Same | Same | | Product Specifications | Similar | Similar | | Component configuration | Same | Same | | Component functions | Same | Same | | Compatible Hemodialysis Equipment | Same | Same | | Labeling | Similar content | Similar content | | Intended use | Same | Same | | Labeled sterile, non-pyrogenic for single use only | Yes | Yes | | Restricted to sale by or on Order of a Physician | Yes | Yes | | Materials | Polysulfone<br>Polycarbonate<br>Polyurethane<br>ABS<br>Polyethylene | Cellulose Acetate<br>Polycarbonate<br>Polyurethane<br>ABS<br>Polyethylene | | Design | Similar | Similar | | Hemolysis | < 3% of Control | < 3% of Control | | Pyrogenicity | Non-pyrogenic | Non-pyrogenic | | Acute Toxicity | Meets USP | Meets USP | | Sterility | Sterile | Sterile | | Leakage | No Leaks | No Leaks | | Sterilization Method | Gamma | Gamma | | Packaging | Foil/PETG tray | Foil/PETG tray | {3}------------------------------------------------ ### VII. FUNCTIONAL TESTING Functional testing has been conducted to evaluate the performance of the PS 15® Hemodialyzer. The results of the functional testing attest that the PS 150 Hemodialyzer conforms to its specifications and has demonstrated the suitability of the PS 15® Hemodialyzer for its intended use. | | PS 150® Hemodialyzer | **Altrex 170 | **Fresenius F60 | |-----------------------------------------|----------------------|--------------|-----------------| | Total Blood Volume<br>Measured (ml) | 79 | 91 | 83 | | Effective Membrane Surface<br>Area (m²) | 1.5 | 1.61 | 1.25 | | Wall Thickness (μ) | 20 | 30 | 40 | | Maximum TMP | 500 | 500 | 650 | | Clearance (ml/min)* | | | | | Urea | 171 | 178 | 185 | | Creatinine | 155 | 163 | 172 | | Phosphate | 141 | 155 | 170 | | B12 | 73 | 106 | 118 | *Q, 200, Q 500 in vitro Qr 10 ml/min UFR **In Vitro Q; 0.0 ml/min The Althin Medical, Inc., PS 15® Hemodialyzer is similar in design, construction, indication for use, and performance characteristics to other commercially available hemodialyzers. The results from nonclinical tests demonstrate that the PS 15® Hemodialyzer is substantially equivalent to predicate devices. ### BIOCOMPATIBILITY TESTING VIII. All appropriate biocompatibility tests have been performed. The following tests were performed: | Test Name | Results | |-----------------------------------------------------------------|---------| | Cytotoxicity Study (USP Elution Method) | Pass | | ISO Sensitization Study in the Guinea Pig (Maximization Method) | Pass | | Subchronic Intravenous Toxicity Study in the Rat | Pass | | Acute Intracutaneous Reactivity Study in the Rabbit | Pass | | Acute Systemic Toxicity Study in the Mouse | Pass | | ISO Muscle Implantation Study in the Rabbit | Pass | | Genotoxicity: Salmonella typhimurium Reverse Mutation Study | Pass | | Genotoxicity: Sister Chromatid Exchange Study | Pass | | Genotoxicity: Chromosomal Aberration Study in Mammalian Cells | Pass | | Rabbit Pyrogen Study | Pass | | Hemolysis Study In Vitro Procedure | Pass | | Microtoxicity and Hemolysis Test | Pass |  {4}------------------------------------------------ The results of the biocompatibility testing demonstrate that the PS 150 Hemodialyzer conforms to the specifications set forth. The subject and legally marketed devices conform to similar specifications see ### IX. Conclusions The information included in this notification demonstrate that the PS 15® Hemodialyzer and predicate device are similar in design, materials, manufacturing processes, performance, safety, effectiveness, intended uses, indications, labeling and institions for use. Therefore, based on the information provided in this premarket notification, the PS 15® Hemodialyzer is considered substantially equivalent to the predicate devices equivalent to the predicate devices. {5}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/5/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
