Indications for Use

The Fresenius Liberty Select Cycler is indicated for acute and chronic peritoneal dialysis.

Device Story

Liberty Select Cycler is a table-top electromechanical device for Automated Peritoneal Dialysis (APD) therapy; treats end-stage renal disease (ESRD). Device uses cassette and tubing sets to manage fluid flow, heating, and drainage; operates via physician-prescribed settings. Used in professional and home settings; operated by patients or clinicians. Software controls fluid delivery, heating, and alarm monitoring. Updated software (v2.8.8) implements a full stroke test for the Patient Line Check (PLC) feature to detect slow-flow or no-flow conditions during the drain phase; triggers immediate soft alarms upon detection. Benefits include improved monitoring of dialysis fluid flow, ensuring therapy efficacy and patient safety during automated treatment cycles.

Clinical Evidence

No clinical data. Evidence consists of software verification and validation testing, including unit, regression, and system-level testing performed in compliance with ANSI/AAMI/IEC 62304:2006 to confirm the functionality of the modified Patient Line Check feature.

Technological Characteristics

Electromechanical table-top cycler. Materials: plastic housing, aluminum heater tray, aluminum cassette housing. Connectivity: optional peripheral wireless modem (3G/4G LTE). Software-controlled fluid flow (45–316 mL/min inflow, 30–286 mL/min outflow) and heating (37°C ± 1°C). Volume accuracy: ± 2% fill, ± 3% drain. Software developed per ANSI/AAMI/IEC 62304:2006.

Indications for Use

Indicated for patients requiring acute or chronic peritoneal dialysis for the treatment of end-stage renal disease (ESRD).

Regulatory Classification

Identification

(1) A peritoneal dialysis 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 a peritoneal access device, an administration set for peritoneal dialysis, a source of dialysate, and, in some cases, a water purification mechanism. After the dialysate is instilled into the patient's peritoneal cavity, it is allowed to dwell there so that undesirable substances from the patient's blood pass through the lining membrane of the peritoneal cavity into this dialysate. These substances are then removed when the dialysate is drained from the patient. The peritoneal dialysis system may regulate and monitor the dialysate temperature, volume, and delivery rate together with the time course of each cycle of filling, dwell time, and draining of the peritoneal cavity or manual controls may be used. This generic device includes the semiautomatic and the automatic peritoneal delivery system.(2) The peritoneal access device is a flexible tube that is implanted through the abdominal wall into the peritoneal cavity and that may have attached cuffs to provide anchoring and a skin seal. The device is either a single use peritioneal catheter, intended to remain in the peritoneal cavity for less than 30 days, or a long term peritoneal catheter. Accessories include stylets and trocars to aid in the insertion of the catheter and an obturator to maintain the patency of the surgical fistula in the abdominal wall between treatments. (3) The disposable administration set for peritoneal dialysis consists of tubing, an optional reservoir bag, and appropriate connectors. It may include a peritoneal dialysate filter to trap and remove contaminating particles. (4) The source of dialysate may be sterile prepackaged dialysate (for semiautomatic peritoneal dialysate delivery systems or “cycler systems”) or dialysate prepared from dialysate concentrate and sterile purified water (for automatic peritoneal dialysate delivery systems or “reverse osmosis” systems). Prepackaged dialysate intended for use with either of the peritoneal dialysate delivery systems is regulated by FDA as a drug.

Special Controls

*Classification.* Class II (special controls). The following accessories are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9: A catheter finger grip that is non-patient contacting and intended for single use with a peritoneal catheter; a continuous ambulatory peritoneal dialysis (CAPD) belt; and a catheter stand that does not include weigh scales.
