The document describes a software-controlled electromechanical device for peritoneal dialysis with no mention of AI or ML capabilities. The software controls basic functions like fluid flow, heating, and alarms based on physician prescriptions.
Yes.
The device is used to perform peritoneal dialysis therapy for the treatment of end-stage renal disease (ESRD), which qualifies it as a therapeutic device.
No
The device is indicated for treatment (peritoneal dialysis), not for diagnosing a condition.
No
The device description explicitly states it is an "electro-mechanical medical device" and a "software-controlled electromechanical medical device," indicating it includes hardware components beyond just software.
Based on the provided information, the Fresenius Liberty Select Cycler is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is for "acute and chronic peritoneal dialysis," which is a treatment for end-stage renal disease. This is a therapeutic procedure performed on the patient's body, not a diagnostic test performed on a sample taken from the body.
- Device Description: The description details an "electro-mechanical medical device" that controls fluid flow, heating, and alarms during peritoneal dialysis. This aligns with a therapeutic device, not a device used to analyze biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (like blood, urine, or tissue), detecting specific analytes, or providing diagnostic information based on in vitro testing.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The Fresenius Liberty Select Cycler's function is to perform a therapeutic treatment directly on the patient.

Device Description
The Liberty Select Cycler is an electro-mechanical medical device. Software controls the functions of the machine during peritoneal dialysis treatment, including fluid flow, heating, and alarms.
Like the predicate device, the modified Liberty Select Cycler is a software-controlled electromechanical medical device designed as a table-top unit to deliver Automated Peritoneal Dialysis (APD) therapy for the treatment of end-stage renal disease (ESRD). The Liberty Select Cycler is used to perform continuous and intermittent peritoneal dialysis therapies. Treatment settings are programmed based on a physician's prescription.
Also like the predicate device. the modified Liberty Select Cycler is compatible with three (3) accessories:
- Cassette and tubing set
- IQdrive
- Optional peripheral wireless modem (AT&T and Verizon 3G/4G LTE networks)
The software has been updated from version 2.8.8 to modify the Patient Line Check (PLC) feature to use a full stroke test to check for a slow-flow or no-flow condition in the patient line during the drain phase. The software changes also modified the soft alarm feature to sound the alarm as soon as a slow-flow or no-flow condition is detected.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing requirements were determined through the application of a risk management process, applicable FDA guidance documents, and performance standards (21 CFR §876.5630). Performance testing to support the determination of substantial equivalence included testing in compliance with ANSI/AAMI/IEC 62304:2006.
Unit, software, regression (system verification), exploratory, and validation testing were performed to demonstrate the effectiveness of the software modifications and to confirm operation of the machine.
No mechanical or acoustic tests were performed.
The software modifications from version 2.8.7 to version 2.8.8 did not introduce any new userelated risks or create any changes in the user interface or operation of the Liberty Select Cycler. Labeling modifications involve minor administrative changes with no impact to risk. Therefore, no human factors testing was performed.

§ 876.5630 Peritoneal dialysis system and accessories.
(a)
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.
(b)
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.
