This device is indicated for single and multiple use.

Device Story

CLIRANS T-Series Hollow Fiber Dialyzer functions as component of artificial kidney system; treats renal failure or toxemic conditions. Device utilizes cellulose hollow fibers (9μ wall thickness) housed in acrylonitrile-styrene copolymer. During operation, patient blood is pumped via roller pump into arterial end; blood flows through fibers while dialysate circulates externally. Waste products diffuse across membrane into dialysate; purified blood returns to patient via venous end. Used in clinical settings by healthcare professionals. Performance metrics include urea, creatinine, phosphate, and Vitamin B12 clearance, plus UFR and priming volume. Biocompatible materials ensure safety during extracorporeal circulation.

Clinical Evidence

Bench testing only. Performance evaluated via in vitro and in vivo clearance tests for urea, creatinine, phosphates, and Vitamin B12. Additional testing included UFR, priming volume, and biocompatibility per ISO-10993. Sterilization validated to SAL 10^-6 per AAMI guidelines.

Technological Characteristics

Hollow fiber dialyzer; cellulose fibers (9μ wall); acrylonitrile-styrene copolymer housing; polypropylene blood ports; silicone rubber O-rings; polyurethane adhesive. Sterilized via ethylene oxide. Biocompatible per ISO-10993. No software or electronic components.

Indicated for patients with renal failure or toxemic conditions requiring hemodialysis treatment using an artificial kidney system.

Regulatory Classification

Identification

A hemodialysis system and accessories is a device that is used as an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and that consists of an extracorporeal blood system, a conventional dialyzer, a dialysate delivery system, and accessories. Blood from a patient flows through the tubing of the extracorporeal blood system and accessories to the blood compartment of the dialyzer, then returns through further tubing of the extracorporeal blood system to the patient. The dialyzer has two compartments that are separated by a semipermeable membrane. While the blood is in the blood compartment, undesirable substances in the blood pass through the semipermeable membrane into the dialysate in the dialysate compartment. The dialysate delivery system controls and monitors the dialysate circulating through the dialysate compartment of the dialyzer.(1) The extracorporeal blood system and accessories consists of tubing, pumps, pressure monitors, air foam or bubble detectors, and alarms to keep blood moving safely from the blood access device and accessories for hemodialysis (§ 876.5540) to the blood compartment of the dialyzer and back to the patient. (2) The conventional dialyzer allows a transfer of water and solutes between the blood and the dialysate through the semipermeable membrane. The semipermeable membrane of the conventional dialyzer has a sufficiently low permeability to water that an ultrafiltration controller is not required to prevent excessive loss of water from the patient's blood. This conventional dialyzer does not include hemodialyzers with the disposable inserts (Kiil type) (§ 876.5830) or dialyzers of high permeability (§ 876.5860). (3) The dialysate delivery system consists of mechanisms that monitor and control the temperature, conductivity, flow rate, and pressure of the dialysate and circulates dialysate through the dialysate compartment of the dialyzer. The dialysate delivery system includes the dialysate concentrate for hemodialysis (liquid or powder) and alarms to indicate abnormal dialysate conditions. This dialysate delivery system does not include the sorbent regenerated dialysate delivery system for hemodialysis (§ 876.5600), the dialysate delivery system of the peritoneal dialysis system and accessories (§ 876.5630), or the controlled dialysate delivery system of the high permeability hemodialysis system § 876.5860). (4) Remote accessories to the hemodialysis system include the unpowered dialysis chair without a scale, the powered dialysis chair without a scale, the dialyzer holder set, dialysis tie gun and ties, and hemodialysis start/stop tray.

Proprietary Device Name: CLIRANS® T-Series Hollow Fiber Dialyzer

Classification Name: Dialyzer, Capillary, Hollow Fiber

Common Name: Hollow Fiber Dialyzer

## INTENDED USE

The CLIRANS® T-Series Hollow Fiber Dialyzers are devices used as part of an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and that consists of an extracorporeal blood system, a conventional dialyzer, a dialysate delivery system, and accessories. This device is indicated for single and multiple use.

## DESCRIPTION

The CLIRANS® T-Series Hollow Fiber Dialyzers consists of cellulose hollow fibers with 9μ wall thickness. Blood is pumped via a roller pump from the artery of the patient into the arterial end of the dialyzer. The blood travels down through the dialyzer fibers where waste products pass through the membrane of the dialyzer into the dialysate, which is constantly circulating through the dialyzer on the outside of the hollow fibers. Blood then exits the venous end of the dialyzer back to the patient.

## SUBSTANTIAL EQUIVALENCE

The CLIRANS® T-Series Hollow Fiber Dialyzers submitted in this 510(k) are substantially equivalent in intended use, design, technology/principles of operation, materials and performance to the largest effective surface area dialyzer (CL*M151L) cleared in the CLIRANS® TAF Hollow Fiber Dialyzer 510(k) K854280.

## PRINCIPLE OF OPERATION/TECHNOLOGY

The CLIRANS® T-Series Hollow Fiber Dialyzers operate in the following manner. Blood is taken from the artery of a patient and pumped via a roller pump into the arterial end of the dialyzer. The blood travels down through the dialyzer fibers, and waste products then pass through the membrane of the dialyzer into the dialysate which is constantly circulating through the dialyzer on the outside of the hollow fibers. Blood then exits the venous end of the dialyzer, and back into the veins of the patient.
