The device is intended for use in patients who have chronic renal failure or acute renal failure, for only single use.

The symbols on the left side are less clear, but they seem to be some kind of handwritten characters. The text is written in black ink on a white background. # K613418 {1}------------------------------------------------ Page 2/4 KO13418 The membrane fibers are made of modified cellulose (i.e., alkyl ether polymer grafted cellulose), derived from cuprammonium rayon. The cuprammonium rayon is manufactured to have a thin layer of modified cellulose exposed to blood contact surfaces. The modification to the cellulose vields the fiber more compatible to the patient's blood, manifested through lower complement activation (C3g and C52) when compared to regular cellulose membrane dialyzers. The membranes are housed within a plastic casing of styrene butadiene block polymer. Non-removable casing end caps are also made of styrene butadiene block polymer. The potting material (sealant) is polyurethane and the port caps (stoppers) are made of hydrogenated styrene butadiene block polymer. Like the AM-BIO Series Dialyzers, the AM-BIO Extended Range Series Dialyzers will be offered for sale in both a "wet" model and a "dry" model. The wet and dry dialyzers are identical to each other except that the wet models are filled at the factory with a fluid to facilitate priming by the user and the dry models are not filled. The use of a wet or dry dialyzer is a matter of user preference. The fluid in wet dialyzers is made of water containing 600 ppm sodium pyrosulfite and 300 ppm sodium carbonate. Asahi AM-BIO Extended Range Series Dialyzers are sterilized by gamma radiation before shipment. ## INTENDED USE The indications for use for the Asahi AM-BIO Extended Range Series Dialyzer is as follows: - Asahi AM-BIO Extended Range (AM-BIO-HX series) Dialyzers are a. intended for use for hemodialysis treatment of patients who have chronic renal failure or acute renal failure. - Asahi AM-BIO Extended Range (AM-BIO-HX series) Dialyzers must be b. used in accordance with the instructions of a physician familiar with hemodialysis and familiar with the conditions of the patient. {2}------------------------------------------------ - Asahi AM-BIO Extended Range (AM-BIO-HX series) Dialyzers are c. intended for single use only. - đ. Asahi AM-BIO Extended Range (AM-BIO-HX series) Dialyzers are designed only to be used only on dialysis systems equipped with volumetric ultrafiltration controllers. - e. The expiration date of ASAHI AM-BIO Extended Range (AM-BIO-HX series) Dialyzers is 3 years from the sterilization date. The user must use the dialyzers before the expiration date. ## Comparison of Device Characteristics to Predicates The indications for use, design, and manufacturing of the Asahi AM-BIO Extended Range Series Dialyzers are the same as a predicate device, the AM-BIO Series Dialyzers. The AM-BIO Extended Range Series Dialyzers have the same materials and construction as the AM-BIO Series Dialyzers, but with extended range of performance specifications to accommodate a more diverse patient population. The intended changes in performance specifications are achieved by changing the pore size of the dialyzer fibers. Note, the AM-BIO Extended Range Series Dialyzers are labeled for only single use. ## Non-clinical Testing In-vitro testing of the AM-BIO Extended Range Series Dialyzers includes the following: - Permeability saline . - ◆ Permeability - bovine plasma - Urea clearance rate ● - Creatinine clearance rate ● - . Phosphate clearance rate {3}------------------------------------------------ Additionally, the following testing supports the biocompatibility of the AM-BIO Extended Range Series Dialyzers: - Cytotoxicity ● - Sensitization . - Irritation or Intracutaneous Reactivity . - Systemic Toxicity (Acute) ● - Genotoxicity: ● - Hemocompatibility . - Pyrogenicity ◆ ## CONCLUSIONS The indications for use (other than regarding single use), design, and manufacturing of the Asahi AM-BIO Extended Range Series Dialyzers (AM-BIO-HX series) are the same as, and therefore substantially equivalent to, the predicate Asahi AM-BIO Series Dialyzers. {4}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/4/Picture/1 description: The image shows the logo for the Department of Health & Human Services - USA.
