The summary describes a software-controlled electromechanical device for peritoneal dialysis with programmed treatment settings and data logging. There is no mention of AI, ML, or any features that would suggest the use of such technologies for decision-making, pattern recognition, or adaptive control beyond pre-programmed parameters.
Yes
The device is explicitly indicated for the "treatment of end-stage renal disease (ESRD)" and performs automated peritoneal dialysis, which is a therapeutic intervention.
No
The device is described as a Cycler for peritoneal dialysis, which is a treatment for end-stage renal disease, not a diagnostic device. It delivers and manages the dialysis solution, and monitors drained fluid, but does not provide a diagnosis.
No
The device description explicitly states it is a "software-controlled electromechanical device" and details various hardware components like a Control Panel, Pump Module, Cassette Compartment, and disposable sets.
Based on the provided information, the Liberty PDx™ Cycler is not an In Vitro Diagnostic (IVD) 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 involves physically exchanging fluids in the peritoneal cavity to remove waste products, not analyzing samples of bodily fluids or tissues in vitro (outside the body).
- Device Description: The device description details an electromechanical system that pumps and manages fluids for dialysis. It does not describe any components or functions related to analyzing biological samples.
- Anatomical Site: The anatomical site is the peritoneal cavity, which is where the dialysis treatment takes place in vivo (within the body).
- Performance Studies: The performance studies mentioned focus on electrical safety, EMC, biocompatibility, and usability, which are typical for medical devices used for treatment, not for IVD devices which would focus on analytical performance.
IVD devices are specifically designed to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The Liberty PDx™ Cycler's function is to perform a therapeutic procedure (dialysis) directly on the patient.

Device Description
The Liberty PDx Cycler is a software-controlled electromechanical device designed for use in Automated Peritoneal Dialysis (APD) therapy for the treatment of end-stage renal disease (ESRD). The Liberty PDx Cycler is designed as a table-top unit for use with single-use, dedicated disposable set (referred to as Liberty PDx Cycler sets). The Liberty PDx Cycler may be prescribed for either clinical or home treatment settings, as the predicate Liberty Cycler. Treatment settings, such as the amount of solution to be infused and the length of time the solution remains in the peritoneal cavity, are programmed into the cycler. During treatment, the Liberty PDx Cycler heats the peritoneal dialysis solution prior to patient infusion, measures and delivers a predetermined amount of fluid to the patient, and monitors the drained volume.
The Liberty PDx Cycler system consists of a Control Panel (user interface), Pump Module, Cassette Compartment, a disposable Cycler set (single-use), IOdrive, and an optional peripheral cellular modem. The control panel consists of a touchscreen display and front panel keys which provide a user interface. The pump module consists of mushroom-head piston(s) that are linearly displaced to alternately draw the dialysate solution to and from the patient's peritoneal cavity. The cassette compartment provides the interface for the disposable cycler set with the pump module's mushroom-head pistons. The cycler set is connected to a number of tubes which, in turn, connect to the dialysate solution bags, the patient, or a drain and provide a flow path between the cycler and the patient. At the end of each treatment, data generated by the Liberty PDx Cycler and stored in battery-backed memory are read and written to a treatment data set on the IQdrive (USB memory stick). Additionally, an optional peripheral cellular modem can also be used with the Liberty PDx Cycler to transmit treatment data files to an FTP server at the end of each treatment.
The Liberty PDx Cycler set is loaded into the cassette compartment of the Liberty PDx Cycler at the initiation of treatment. The cassette is composed of a ridged molded plastic (polypropylene) body covered with a flexible film/membrane. The cassette contains molded features, such as fluid channels, flexible valve domes and two (2) pumping chambers that are acted upon by the cycler to direct the flow of the peritoneal dialysate to and from the patient's peritoneal cavity.
There are seven (7) fluid lines connected to the cassette:
- . One (1) drain line
- . One (1) patient connection line (with one (1) or two (2) stay safe® patient connectors depending on the model)
- . Five (5) Dialysate Solution Lines (with Safe-Lock® connector):
- One (1) heater bag
- One (1) last dialysate bag/'last bag option'
- Three (3) additional solution bags -
The three Liberty PDx Cycler sets designed for use with the Liberty PDx Cycler are constructed from identical materials. The sets differ only in the length of lines or in the number of patient connectors, as described in Table 1.

§ 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.
